Executive Summary
Deliverable 4.2 (Interim report on metadata creation) is a first overview of all the aspects
concerning the creation of the metadata of the 3D objects that will be supplied to
Europeana by the partners. The report concerns the progress of the metadata creation, the
problems encountered and the actions undertaken within the framework of the task 4.2.
supervised by CISA with the collaboration of MAP. The task, started at the month 12 of the
project, is related to all semantic improvements defined in the WP6 and to the analysis of
the preexisting legacy data already created by the partners in other research, but not
compliant with the standard adopted by the project. Finally, the task aims to identify
guidelines for the definition of the relationships between the quality control, established in
task 2.2, and new elements introduced in the new CARARE 2.0 schema.
After the approval of the new CARARE 2.0 schema (Deliverable 6.1), some case studies
have been chosen and tested. Starting from the analysis of the results obtained and from
the activities carried out by the partners, two workshops have been organized in 2013 with
the scope to identify a set of common approaches aiming to harmonize the elaboration of a
pipeline for the metadata and of a strategy for the definition of paradata and provenance
information.
This interim report begins with the progress on metadata creation with a particular focus
on the problems encountered and actions undertaken (see Section 1). Section 2 introduces
a simplistic approach on creating metadata provided by CETI with the contributions of
CISA and MDR, while section 3 deals with a metadata editor tool designed and developed to
facilitate the metadata creation by each partner and by the new or future associate
partners. The metadata enrichment is provided in the section 4. The mapping and the final
publication procedures are discussed in the section 5 with the related tools (MINT2 and
MORE2). In the conclusions some proposals are outlined for the further steps of this
activity and the definition of a well-consolidated pipeline from the 3D model to the
metadata ingested into Europeana. In Appendix A, an XML file is provided as a practical
example of a real record encoded according to the CARARE 2.0 schema.
After the annual Technical Review, held in Brussels on 1st April 2014, the 5.1 paragraph
and the Conclusions have been partially re-written on the basis of the reviewers’
recommendations. The paragraphs give an overview on the methodology for the metadata
creation, in order to mitigate potential risks with respect to metadata-delivering to
Europeana; and shows some tables allowing the monitoring of the publication process.
Furthermore, issues concerning statistic and rights are also shown. Two checkpoints, in
months 30 and 33, have been introduced in order to undertake an in-depth review and
needed remedial actions to reduce possible further delays.

1. Metadata creation activities: problems encountered and
actions undertaken
In March 2013, CISA, with support from MDR, delivered the new metadata schema
(CARARE 2.0) for 3D models (Deliverable 6.1). The original CARARE schema was improved
in light of experience gained from ingestion of metadata to Europeana in the CARARE
project and mapping to the EDM along with an extension which included provenance and
technical data (London Charter paradata). CETI also participated in the evolution of the
CARARE schema to CARARE 2.0 and focused on a number of issues related with the
collection of 3D digitization metadata and how these will be organized in the extended
version of the initial CARARE schema.
After the approval of the deliverable, which occurred at the end of June, CETI dealt with the
creation of the XSD schema on the basis of the approved deliverable. Later CETI, in
collaboration with CISA and MDR, started some technical tests in order to implement an
XML file sample according to the schema and compliant with its cardinalities and
compulsoriness. An outline of the mapping on EDM has been also implemented.
The metadata creation activity has not yet started due to various reasons. Firstly, the
deliverable on the new metadata schema was submitted in March and approved at the end
of June; so tests on the schema started after this. Furthermore, an important issue emerged
during period 3; that is when the project began, the overall metadata status of each partner
was not clear. Only three partners had participated in CARARE (CAAI, CETI and STARC) and
were already experienced with metadata, existing schemas and tools (although some
updates must be carried out for 3D-ICONS), while the majority of the other partners were
not familiar with creating metadata from scratch or their schemas wasn’t compatible with
the new CARARE 2.0 without extensive transformations. While the previous CARARE
project adopted a schema able to capture automatically, by means of a targeted mapping
carried out by the tool MINT, the information included in National or local repositories and
archives to CARARE 1.0 and finally to the Europeana model, 3D-ICONS updated the
CARARE 1.0 schema mainly for data that wasn’t present in pre-existing databases or
national standard.
A short summary of the diverse situations of some partners and the existing different
issues in terms of metadata, mapping and final publication follows:
CYI-STARC has already started with the creation of the metadata files according to its
CARARE-compliant schema. CYI-STARC has an estimate of hundreds of deliverable
products associated with the corresponding metadata files. However, some of the new

3
fields introduced into the CARARE 2.0 schema do not map to the existing CYI-STARC
schema, an issue which is currently being worked on.
UJA-CAAI is revising their metadata to comply with the new CARARE 2.0 schema (they
used the original CARARE schema).
POLIMI has most of their metadata recorded on the base of a regional standard (SIRBEC)
only partially compliant with the CARARE Schema. As their schema does not contain all of
the required elements (e.g. there is no information on the acquisition and creation of the
3D model) more metadata will be added. They probably will be able to complete and start
mapping their metadata in MINT2 soon.
DISC has produced an in-house spreadsheet for the creation of metadata to enable
migration as csv file to the Discovery Programme’s DSpace repository. Fields within the
spreadsheet conform to Dublin Core and associated CARARE mappings as detailed in
CARARE V1.0 documentation. Consequently, some additional data will be added to be
compliant with CARARE 2.
MAP developed, within the framework of other projects and research, its own schema for
the 3D data that is incompatible with the CARARE 2.0 schema. MAP will try to map its
schema on CARARE 2.0 and add the required new information in relation to provenance
and paradata.
CETI has completed the post-processing of the Kioutouklou Baba Tekke monument 3D
model and the post processing of 3D data from two other monuments (Panagia Kalamou
and Kosmosotira) is currently in progress. A CARARE 2.0 schema-based metadata example
for the Kioutouklou Baba Tekke monument has been created. The current example carries
information about the actual heritage asset but also depicts in detail the relations between
the different data collection phases and post-processing phases that were performed in
order to create the monument’s 3D digital replica.
The remaining content provider partners will start from scratch their activity of metadata
creation.
To provide training and overcome the above mentioned difficulties, two workshops were
organized. The first was organized by CETI along with NTUA and held in Xanthi, Greece, 27-
29 June 2013, the latter in Marseilles on the 30th and 31st October 2013, organized by MDR
and MAP in the framework of the International Congress DigitalHeritage2003. The training
covered the new CARARE metadata schema and the use and functionality of the MINT2 and
MoRE2 tools. Furthermore, a metadata creation tool approved in the meeting held in

4
Naples at the beginning of September and later developed by CETI has been discussed,
revisited and tested. After the Marseilles workshop, some partners started creating
metadata for import into MINT2 on a test basis, others are testing the metadata editor tool
which is not yet completely operational (some final improvements and bug fixes are being
implemented).
Consequently, 3DICONS has had to widen its remit to help partners who have little or no
metadata experience by defining a process and providing tools to enable metadata to be
created from scratch as efficiently and easily as possible.
2. A simplistic approach on creating metadata
At the end of October, after a long revision process, an internal report was provided by
CETI in collaboration with CISA and MDR. The report, entitled “Providing XML Metadata in
the CARARE 2.0 schema. A simplistic approach on creating metadata for the 3D-ICONS
project”, contains some guidelines to assist the partners to generate their metadata files.
The report provides a simple procedure for creating metadata complying with the CARARE
2.0 schema.
All 3D digital models provided by the 3D-ICONS project to Europeana are associated with
metadata registered according to the CARARE 2.0 schema. Each 3D digital replica is defined
as an entity or a detail and it is assigned as a heritage asset according to the CARARE 2.0
schema and thus must be followed by its own metadata (including provenance and
paradata).
The simplistic pipeline of metadata creation and provision can be divided into three steps:
1. Creating a blank XML file template utf-8 file preparation and metadata input
2. Upload to MINT 2.0 tool and XML validity check
3. Publication to MORE 2.0 tool
The pipeline can be considered as a solution by a partner that doesn’t have legacy metadata
(e.g. Database with metadata following a different schema). It is based on the scenario that
the content provider wants to create their metadata from scratch. The proposed process is
divided into two main phases, the first one is the preparation and the second one is the
creation of a template xml file.
The first phase of the process aims at creating a blank XML file. Starting from the XSD file of
the CARARE 2.0 schema, a blank file containing a list of all elements can be generated by an

5
XML software. The generated file corresponds to the schema following its cardinality
definitions. The above mentioned report identifies a list of software to facilitate the work of
the partners with no (or low) experience in the field of the metadata creation.
Then each partner can reuse this XML file following the procedures in order to create a
template (Fig. 1):
1. Opening a generated blank CARARE 2.0 XML file in a text editor and identifying the
schema elements that are frequently repeated. The values that are expected to be
common for each partner are for example organisation name and address, contact
persons, IPR rights, digitisation team members, equipment, methodologies or even
digitisation activities. Some other elements could be in common among the
partners, e.g. methods, list of terms (for event_type). Once these elements are
identified, the partner can save the file using a different filename. This file can now
be considered as the primary XML template file that has been adapted to the partner
needs in terms of elements and common content. In the Appendix A it is possible to
evaluate the common elements found in the Kioutouklou Baba Teke and how these
have been managed.
Finally the template can be opened in an editor and completed. It must be noted that all
mandatory elements should be kept in order for the XML file to pass the validation check in
MINT 2.0.

The report also deals with the relation between the different themes of the schema. Fig. 2
shows a practical view of how to link correctly the digital replica (Heritage Asset) to
specific Activities (Digitization, Post-processing, decimation, etc.) by means of the relation.
The name of each relation indicates the type of relationship and the content of these
elements, usually Ids or URI, according to the following schema:
HeritageAssetIdentification
<hasRepresentation> </hasRepresentation>
<wasPresentAt></wasPresentAt> 
<hasPart></hasPart> 
<isPartOf></isPartOf> 
<isReplicaOf></isReplicaOf> 
<wasDigitizedBy> </wasDigitizedBy>

<isPartOf> </isPartOf> 
<hasCreated> </hasCreated>

3. Metadata Editor Tool
The approach described in the previous section is an easy way to create metadata
compliant with the schema adopted by those partners with no particular or low
competence in the metadata field. Nevertheless, this procedure, based in substance on the
copy of the preceding record, could easily lead to some mistakes being made, mainly by
those partners having a large quantity of 3D models to be provided to Europeana.
For these reasons, an on-line metadata editor tool (http://3dicons.dcu.gr/metadata-
editor/), has been designed and implemented to support and facilitate partners in the
metadata creation. The results and the experience gained in the test phase during the
development of the approach shown previously have been relevant for the design of the
tool. Another important consideration in developing a specific tool lies in the possible
further utilization of the schema by data providers associated or not associated to 3D-
ICONS project dealing with creation and publication of 3D models with a need to create the
metadata.
The tool is basically set up on the declarations of blocks or groups of information that are
repeated for each record and that the partners can choose from a drop-down list. These
are: Organization, Collection, Actor, Activity, Spatial data, Temporal data and Digital
Resources (Fig. 3).

8
Figure 3 - The setting up of the basic information
The tool is accessible with a password dedicated for each partner. In order to avoid
mistakes and confusion, each partner can reuse only the block of information that it filled.
In addition to the menu for Home, Classes, the main page includes a Publication Console
aimed at giving an important function to control the correctness of the filled data.
After compiling the initial blocks of information, the metadata author can proceed to the
adding of a record starting from Heritage Asset. In a few simple steps, it is possible to
complete a record. In the first two steps the author can recall (Fig. 4) the information
already loaded (Organization, Collection) from an existing list. Before creating a Heritage
Asset it is also possible to add information for Digital Resource and this information will be
recalled in the specific tabs under the Heritage Asset form (Fig. 5).
If the author wants to create a Digital Resources and Activity independently from the
Heritage Asset section, they can use the corresponding forms (Figs 6-8). Later this
information will be present in the Heritage Asset form (Fig. 9). At the end of the form filling,
the author can visualize the object in a list and browse or export the corresponding XML
file (Fig. 10).

4. Metadata enrichments
In the section 6 of deliverable D6.1 same recommendations on the metadata enrichments
and LOD are provided to help partners to create resources by using persistent identifiers or
by identifying standardized references (URI). As the standardization will facilitate
implementing Linked Open Data, the section 5 of the deliverable gives a list of Thesaurii
and Authority Lists (The ICCD/CulturaItalia, The Getty Research Institute, English Heritage,
The European Heritage Network (HEREIN), Mérimée, Royal Museum of Art and History of
Bruxelles). The use of widely accepted lists and standard will contribute to the
development and promoting the use of semantic tools enabling interoperability, integration
and reuse of 3D models via Europeana for professional, research and commercial purposes.
During the internal reviews and discussions, some relevant conclusions have been achieved.
They represent a common approach about how the partners have to consider the objects
and the associated metadata. This approach is also based on an Europeana attempt to
enrich data by adding standard and multilingual terms and references to answer who,
where and when questions. The following two recommendations, set up to standardized
the metadata creation, concerns the element of CARARE that will be mapped on the main
classes of Europeana1. The use of URI assists the conversion of EDM records in EDM
records compliant with the standard LOD.
1) Managing the relation between the physical object and one or multiple digital
replicas.
A Heritage Asset (HA) corresponds to the digital object (type=3D). The partner can use
online resource or bibliographical references to define the relation between physical object
and the digital replica provided to Europeana. It can also use a generic link, e.g. to
Wikipedia or whatever, describing the object. In general, it is preferable to use a permanent
address or an URI to guarantee long term website links. Each HA will be an
EDM:ProvidedCHO. Multiple digital views of the same physical object could be different
HAs (e.g. high and/or low resolution; decimation or simplification of the model; different
reconstructive hypothesis, etc.) or different DRs (e.g. images 2D of the same 3D Model).
This approach will not automatically apply to the all digital objects, but will be decided by
the partners in relation to the different provenance and paradata information described
and mainly in relation to the copyright agreements signed with the Institution in charge of
the safeguard of the archaeological monuments that will be delivered to Europeana. For
example, a partner could acquire various statues and small findings and submit a virtual
reconstruction of an ancient environment (monument, temple, cemetery, etc.) according to
well known hypothesis, or to make available with “Free Access No Reuse” rights statement
1 http://pro.europeana.eu/linked-open-data

14
a low resolution model and make accessible that with higher resolution only through
specific authorization.
2) Enrichment data (see http://pro.europeana.eu/web/guest/providers-faq)
For Actors, Concepts, Places, Time the recommendation is to use available ontologies, URI or
permanent links. This will ease the migration of the resources in the Linked Open Data format.
ACTORS: Person names can be matched to DBpedia (http://dbpedia.org/About) entries to
give a unique identifier for the name. This links to additional information about the person,
and enables the display of multilingual versions of the name in the portal. For the the
organizations/institutions it is possible to use FOAF (http://www.foaf-project.org/ or
VIAF: http://viaf.org/).
CONCEPTS: Concepts are matched to the terms in the Gemet thesarus
(http://www.eionet.europa.eu/gemet) which provides a unique reference for the concept.
It also enables the display of the term in many languages and a display of the references
and labels of broader terms. For the Humanities another good reference is the Getty
Thesaurus (http://www.getty.edu/research/tools/vocabularies/aat/).
SPACE: Places are matched to place names in GeoNames (http://www.geonames.org/).
This gives a unique reference for the place name, enables the display of multilingual
versions of the names, the display of geographic coordinates and broader geographic areas
associated with the place. For the Ancient places another good reference is the Pleiades
(http://pleiades.stoa.org/).
TIME: time periods can be enriched from a vocabulary developed using the Annocultur tool
(http://annocultor.eu/) which can now be found at http://semium.org/time.html. This
establishes a unique reference for the time period with start and end dates and can also
connect to the name of historical periods.
5. Mapping and publication
For the mapping and the publication (ingestion) of the metadata into Europeana, 3D-ICONS
customized two tools (MINT22 and MORE23) already developed in other European projects,
mainly CARARE. The tool were modified to import, visualize and validate automatically
2 http://mint-projects.image.ntua.gr/3dicons/Login.action
3 http://3dicons.dcu.gr/index.php

15
records compliant with the CARARE 2.0 schema or import and map other metadata. The
new CARARE 2.0 schema was installed in the two systems and all procedures to validation
were accordingly aligned to check the correctness of the metadata creation and their
quality on the basis of the cardinalities of the CARARE schema.
NTUA has been focused on setting up the MINT2 tool to provide improved functionality
regarding the mapping functionality and dataset upload and publication. In the new
version, providers can publish datasets into MoRE2 without having to publish all datasets
belonging to one provider. It also includes an improved reporting tool to monitor the
progress of the ingestion.
MINT2 services compose a web based platform that was designed and developed to
facilitate aggregation initiatives for cultural heritage content and metadata in Europe. It is
employed from the first steps of such workflows, corresponding to the ingestion, mapping
and aggregation of metadata records, and proceeds to implement a variety of remediation
approaches for the resulting repository. The platform offers a user and organization
management system that allows the deployment and operation of different aggregation
schemes (thematic or cross-domain, international, national or regional) and corresponding
access rights. Registered organizations can upload (http, ftp, OAI-PMH) their metadata
records in xml or csv serialization in order to manage, aggregate and publish their
collections.
A reference metadata model serves as the aggregation schema to which the ingested
(standard or proprietary) schemata are aligned to. Users can define their metadata
crosswalks with the help of a visual mappings editor for the XSL language. Mapping is
performed with simple drag-and-drop or input operations which are then translated to the
corresponding code. The mappings editor visualizes both the input and target XSD, in an
intuitive interface that provides access and navigation of the structure and data of the input
schema, and the structure, documentation and restrictions of the target one. It supports
string manipulation functions for input elements in order to perform 1-n and m-1 (with the
option between concatenation and element repetition) mappings between the two models.
Additionally, structural element mappings are allowed, as well as constant or controlled
value (target schema enumerations) assignment, conditional mappings (with a complex
condition editor) and value mappings between input and target value lists. Mappings can
be applied to ingested records, edited, downloaded and shared as templates between users
of the platform.
Preview interfaces present to users the steps of the aggregation including the current input
xml record, the XSLT of their mappings, the transformed record in the target schema,
subsequent transformations from the target schema to other models of interest (e.g.

16
Europeana's metadata schema), and available html renderings of each xml record. Users
can transform their selected collections using complete and validated mappings in order to
publish them in available target schemas for the required aggregation and remediation
steps.
In the following three figures the import (Fig. 11), the mapping (Fig. 12) and, finally, the
visualization (Fig. 13) of the sample reported in the Appendix A have shown.

CETI continued on the development of Monument Repository (MORE2) using a new server.
The system has been setup to accept information packages from the MINT2 system,
transform them and deliver them to Europeana (Figs. 14-16).

5.1 Monitoring the Metadata
3D-ICONS has to keep track of the metadata created by each provider. The metadata
provided by each partner can be uploaded to MoRE2 as individual records or (more
commonly) as a batch of records. After checking and transformation (via the XSLT), the
records are supplied to Europeana for ingestion. MoRE2 provides a quality check for each
package ingested and indicates the status of the package. Those that do not pass the check
at this stage are shown in the Not Ingested page. Once uploaded, the Europeana Ingestion
team checks for completeness of mandatory elements, the validity of links and other checks
before ingestion, and can also enrich the metadata before it is published – this process
takes one month with publication to the live Europeana service happening once a month.
If there is a problem with the metadata, then the Ingestion team will inform the relevant
contact (CETI) for the project who will assist the partner(s) to correct the identified issues
and reload the corrected metadata into MoRE2. At any point in time, it is possible to see
how many records a partner has loaded into MoRE2 and how many have been ingested by
Europeana. This means that providers can track their publications across the two systems.
When each package is harvested by Europeana, it is marked as delivered.

20
It is possible to visualize the metadata created and not yet harvested by Europeana
through the 3DICONS portal. In this way the Consortium set up two different checks: the
former is based on the quality control process informing the partners of possible errors or
data inconsistency of the ingested metadata and a latter, no less important, gives
information about the numbers of published metadata created by each partner.
The first trial ingestion was planned for the 15th May. Some content providers uploaded
metadata packages. A variety of upload methods have been used, the majority of partners
using the Metadata Editor (CISA, DISC, CMC, FBK, CNR, MNIR) to create their first records.
POLIMI opted to export from existing databases, adding any required missing fields and to
upload the resulting CSV files into MINT2 and map the data to CARARE2 for import into
MoRE2. CYI-STARC used the standard OAI-PMH method established in the CARARE project
to import their existing XML records into MINT2 and MAP these to the CARARE2 schema.
No specific problems were identified with the metadata import methods. KMKG and UJA-
CAAI who have used MINT in previous projects will provide their data in batches from July
(exports from existing databases normally create larger batches) onwards. VisDim
(supplying 50 3D models) have scheduled their ingestion for November to fit in with their
current work schedule. CNRS-MAP provided records by the second target date and
Archeotransfert plan their first batch by the third target date of 4th July.
According to the CARARE 2.0 and EDM schema and on the statistics given by Europeana the
partners considered a digital object as a Carare:DigitalResource mapped on a
corresponding EDM:WebResouces. In this way a Carare:HeritageAsset can be transformed
into a single EDM:ProvidedCHO or to represent a record grouping different digital objects
(3DModel at different resolution, 2DImages, Video) replicating the same physical object.
Where downloadable formats such as 3D-PDF are used for the models, partners have been
provided a direct link (EDM:IsShownbyto) the digital resource but in most cases, landing
pages (EDM:IsShownAt) are preferred as these allow partners to add additional
information and group related digital assets as well as their own branding.
In the first trial some partners also tested the carousel format provided by Europeana
where the 3D model is a primary digital resource and the related images and videos
displayed as related digital resources. As in total more than 18.000 digital objects will be
delivered to Europeana, the choice to group a 3DModel with other derivative resources (2D
Images and/or videos) represent a good compromise between the final number of item to
be delivered whilst allowing the users to find easily what they are searching for, e.g. the
physical object and possible derivative digital items.
Packages” in the MORE2 system. Metadata owners login to in MORE2, go to “Ingested
Packages”, select “Details” for their Package and set its publication status to “Publish”, and
then check the “Submit” tab. This classifies the metadata as publishable ready to be

21
harvested by EUROPEANA. At the same time, data characterized as publishable will be
harvested by the 3DICONS portal and will appear there within a couple of days. In parallel,
the “published” metadata in MORE2 will be checked once more by the Metadata Quality
Assessment personel (MQAC). If any additional problems are found, an email is sent to the
owners informing them on the results of the Metadata Quality Control. The metadata
owners can view their data by visiting the 3DICONS portal where almost all the CARARE
metadata is displayed in the way visually, similarly to EUROPEANA.
Finally, in approximately one month, the metadata will appear also in EUROPEANA and
owners should again check to see if everything is OK. The MQAC will also look at the
published metadata as a final check for any possible errors that may have occurred due to
mapping in MoRE2.
After the first two trials the complete ingestion process has been set up as follows:
Metadata is uploaded to MORE2, either via the Metadata Editor, or via MINT2, and
assuming that the data passes the semantic checks, the data will appear as “Ingested
6. Conclusions
This interim report presents a first overview of the metadata creation activities. Starting
from the analysis of the existing situation, the experience of the partners in this field and
the issues encountered, the report shows the actions and tools the project has planned to
overcome all potential difficulties and possible delays as quickly as possible.
Firstly, the report introduces a simplicistic approach aimed at giving the partners, with a
medium experience in XML, a practical way to create their metadata starting from a
template record containing a list of information quite often repeated in each record. Then
an on-line tool is shown as a simple way to create metadata and mainly create links
between all resources in terms of relation among Heritage Assets, Digital Resources and
Activities. The enrichment metadata are analyzed in the section 4. The pipeline to publish
data, including two software applications already developed and tested in the previous
CARARE project and customized for 3D-ICONS and the new schema, is introduced in the
section 5.
In short, Figure 17 shows the approach that content provider has to follow to create
metadata for digital replicas from the original monuments or details and identify the
corresponding relationships.

Figure 17 - The approach to metadata creation
The strategy for the metadata creation has to be chosen according to the pre-existing
digital resources or legacy data or on the basis of the existing metadata experience of the
partners. Figure 18 shows possible different trajectories in the use of the available tools
implemented in the framework or the project:

The two metadata training workshops held in Xanthi in June and Marseilles in October
provided valuable feedback for defining the content partner’s requirements and led to the
development of the metadata editing tool as demonstrated at the second workshop where
training was provided for this. All partners have now received training on MINT2 and the
Metadata Tool and further support has been provided through individual training sessions
held via Skype, an online support forum run via Basecamp. Help within the Metadata tool
have been implemented and the Guidelines from CARARE are currently being updated.
Further session has been organised in the project meeting, held in Jaen in March 2014, to
enable partners to discuss specific issues they have with the metadata and ingestion
process and tools with the technical development team (NTUA and CETI) and schema
experts (CISA).
The following tables show the time-table for the metadata creation and ingestion for each

The following graph visualizes the cumulative metadata target. The incremental curve
shows that after an initial slow start, the number of metadata increases rapidly.
Two checkpoints are foreseen at the month 30 and 33:
Month 30 Month 33
3D Models 677 2.054
2D Images 2.244 8.759
Videos 40 217
TOTAL 2.961 11.030
As the consortium tested the pipeline and the methodology in the first two trials, the
targets foreseen for the Months 30 and 33 are easily reachable also considering that the
data-acquisition, the process and the post-processing phase will be completed before the
summer and all partner will focused their activities in the last six months only on the
metadata creation and ingestion.

<description lang="en">The monument is located in the middle of a cultivable area on the west coast of the
Vistonida Lake, near Selino village in Xanthi, Greece. It is considered as one of the most important
Ottoman monuments in the area and it may have been built in the 15th century. It was possibly built on
the ruins of an Orthodox Christian temple that was dedicated to Saint George Kalamitziotis. According to
scholars, the term tekke (gathering place for Dervishes) is erroneous as the only remaining monument
from a possible older building complex (tekke) is a tomb (türbe). Several conjectures have been made
about the person buried in the monument. Today, for the Muslims it is considered as the grave of a
Whirling Dervish named Kioutouklou Baba, while for the Christians it is a worshiping place of Saint
George. It is composed by an octagonal türbe (mausoleum) and a domed antechamber. The türbe has a

28
domed roof, too, and two windows (at the east and south wall) and it is made of hewn
stones.</description>

<description lang="en">This is a high resolution 3D digital replica of the Kioutouklou Baba Bekctashic Tekke
monument.</description>
<generalType lang="en">3D</generalType>
<provenance lang="en">The monument was selected to be 3D digitised within the framework of the EU
funded 3D-ICONS PILOT-B project. As the monument was part of the case studies that have be used for
testing different digitisation pipelines it was captured using different methodologies. More specifically, a
complete exterior digitisation of the monument was carried out in order to assess the multi image-based
(Structure-From-Motion (SFM) and Dense Multi-View 3D Reconstruction (DMVR))method’s applicability.
We evaluated the quality of the resulted 3D mesh by comparing it against the data captured by a Time-of-
Flight (TOF) 3D range scanner, a total station and a set of empirical measurements. In this work, we
considered Agisoft PhotoScan as an all-to-one software solution for the production of digital 3D replicas of
monuments. We evaluated the application of the method in order to create a complete exterior 3D model
of a monument using both terrestrial and aerial photography. We compared the 3D mesh produced
against the data we captured from the same monument using other methods such as terrestrial 3D laser
scanning, total station surveying and empirical measurements using Meshlab and CloudCompare open
source software. The produced data clearly indicated that a SFM-DMVR software can provide high quality
results. But as it is an image based technique, the produced data are highly correlated and depended on
the unavoidable procedure of identifying corresponding points between images.</provenance>

</appellation>
<description lang="en">The 3D data collection phase (fieldwork) of the monument included terrestrial and
aerial photo shooting of the monument. For the terrestrial photo shooting session a DSLR Nikon D40 at 6.1
MP with an 18-55 mm lens along with a tripod has been used. On the other hand, for the aerial photo
shooting session, a remote controlled helicopter has been used. The UAV was equipped with a three axis
pan-tilt-roll remote controlled camera head (360o on the horizontal axis, 220o on the vertical axis and a
rolling ability of 600). A DSLR Canon EOS350d at 8.1MP with an 18-55mm lens has been used for the
aerial photo shooting session. The total number of photographs that has been used for the generation of
the 3D model of the monument was 652 (469 terrestrial photos and 183 aerial photos). The average
distance of the camera from the monument’s surface was estimated at 4 meters.The primary 3D model
was created using a commercial structure-from-motion/dense multi-stereo 3D reconstruction software

37
Agisoft PhotoScan). The software offers a number of predefined 3D reconstruction levels of detail (LOD).
The level of detail affects the density of the reconstructed 3D mesh. In an base case scenario the user
provides the software with an image collection, the system almost automatically calibrates the cameras
based on the EXIF information found in the images, aligns them into the 3D space and produces a
complete and single 3D mesh using a dense multi-view reconstruction algorithm. The total time required
for the software to align the images into 3D space was 26 hours.</description>
