This document discusses legal and other issues related to using open source software. It defines key terms like proprietary software, open source software, and freeware. Both proprietary and open source software have advantages and disadvantages to consider. When sharing or procuring software within the Commonwealth, open source licenses and ownership of the software must be reviewed. A best value analysis is required for procurement to assess risks and benefits of different software options. Resources for comparing open source licenses and the Commonwealth's IT policies are provided.

- 4. Software as IP Software is valuable intellectual property A software license is the contract between the software owner and the licensee defining terms of use of software Software owners also have enumerated rights under the law to control the use and distribution of their property (with few exceptions) The Digital Millennium Copyright Act (DMCA) and contract law typically protect software owners‘ rights
- 5. Typical Proprietary Software License Fairly standard terms Source code availability – Source code not provided - trying to figure out inner workings of software through reverse engineering or decompiling of operating mode is forbidden; OR – Source code provided - may or may not include permission to create modifications and enhancements
- 6. Proprietary Software License terms- Licensees Restrictions on dissemination. Licensee and users strictly defined. Licensee has no right to share with those not defined as licensee users in license; Licensor indemnifies licensees against third party infringement claims; Often, have to sign a new license each time new licensee obtains the code.
- 7. Proprietary Software License terms– Warranty and Support Warranties provided: – Defects in media and existence of viruses, Trojan Horses, backdoors, etc; – Can negotiate for warranties re: meet specifications in product documentation Maintenance and support terms included (although may be in separate document).
- 8. Open Source Software– Main Features Non-proprietary software which may or may not be used commercially; Typically licensed under an Open Source license (not given away) – License terms differ from proprietary software license terms Source code is generally made available – Legal restriction on reverse engineering (under the DMCA) do not apply.
- 9. Open Source SoftwareLicense - Licensees Original software owner or developer chooses to limit the rights that he asserts over licensees Licensees, subject to license terms, can: – make and distribute copies of software; – build upon software to create modifications or other works.
- 10. Open Source SoftwareLicenses - Source Code Source code to original product always provided; Licensee can modify or enhance source code (create ―derivative works‖) or include source code with other license types (create ―larger works‖); Licensee may be required to share modifications with the world (in source and/or binary form), but not necessarily; Licensee may be prohibited from charging royalties for derivative and larger works, but not necessarily.
- 11. Open Source SoftwareLicense – Warranties and Support Generally, software provided ―AS-IS‖ with no warranties, warranties excluded; No indemnification; No maintenance or support.
- 12. The GNU “GeneralPublic License” (GPL) No standard open source license, but GPL most widely used (roughly 85% of open source software); Terms include: – User freedom to distribute and/or modify; – Requirement that original and modified source code be always made available to the world under the terms of the original license; – Must retain copyright notices and warranty disclaimers; – Does not include grant of patent licenses; – Extremely viral license.
- 13. The Mozilla PublicLicense Developed by Netscape for the Mozilla browser Terms include: – Very similar to the GPL but, – Can charge royalties for modified versions; – Can include source code within larger works licensed under different license types, thus license does not ‗infect‘ all downstream projects; – Must retain copyright notices and warranty disclaimers; – May provide additional warranties to downstream users but may have to indemnify original developer for any claims arising as a result; – Includes grant patent licenses; – Less viral than the GPL.
- 14. The IBM PublicLicense Terms include: – User freedom to distribute and/or modify; – No requirement for source code availability in downstream distribution; – The program can be distributed in executable form thus allowing downstream users to develop, sell, and install customized software packages without having to make all customizations available to the world; – Must retain all copyright notices and warranty disclaimers; – Includes grant of patent licenses.
- 15. Open Software License Terms include: – User freedom to distribute and/or modify; – Viral license, source code is always made available to the world; – Must retain copyright notices and warranty disclaimers; – Requires indemnification for attorney‘s fees incurred as a result of potential claims or litigation.
- 16. The Apache SoftwareLicense Governs the Apache web-server software. Terms include: – User freedom to distribute and/or modify; – No requirement for source code to be made available to the world in downstream distribution; – Must retain all copyright notices and warranty disclaimers; – Not a viral license.
- 17. The FreeBSD License Unrestrictive license: – Only requires preservation of copyright notices and warranty disclaimers.
- 18. Summary: Existing open sourcelicenses Terms will always include preservation of copyright notices and warranty disclaimers; Some licenses will be extremely viral: thus prohibiting any other type of downstream licensing apart from under the terms of the original license; Some with permit inclusion of code within proprietized programs; In some instances, provision of additional warranties and support will trigger indemnification provisions to the original developer.

- 20. Freeware Freeware isfree software, software that the licensee can use without paying a license fee. Free software may be proprietary software for which source code is not provided (Adobe Acrobat) or open source software (Linux). Note: Not all open source software is free; not all proprietary software is licensed for a fee.
- 21. Advantages: Proprietary Software Indemnification; Maintenance and support; Licensee doesn‘t have to have open source savvy staff; Licensees‘ rights if: – media is defective; – software contains viruses, backdoors, etc.; – product fails to meet written technical/business specifications.
- 22. Disadvantages: Proprietary Software COST! –License fee – Product bundling—example: Microsoft office. Licensee cannot modify or enhance the code; Often not built to open standards, leading to interoperability problems; Shut off from continuing development and information sharing in open source community; Some proprietary code is not as good as its open source counterparts.
- 23. Advantages: Open Source License PRICE: Generally no or low license fees; Availability of source code coupled with permission to make modifications; Access open source development community, which may be very active with respect to code used. Continuing improvement; outstanding development; More likely to be built to open standards, so interoperable with other open standards systems.
- 24. Disadvantages: Open Source Licensing No indemnification; if a third party claims that licensee is using code that the third party developed, the licensee has no one to pay his legal fees and damage award (SCO v. IBM); No maintenance and support (unless purchased separately); No warranties regarding media, viruses, and performance; Staff must be open source savvy; License terms are NOT standard: thus important to pay close attention to terms.
- 25. Note on Disadvantages:Open Source Many disadvantages of open source licensing can be addressed by procuring open source software through a third party vendor that will provide maintenance, support, additional warranties, etc.
- 26. Sharing Proprietary Software Withinthe Commonwealth Agencies can share proprietary software if proprietary license names the Commonwealth, rather than agency, as licensee and other license restriction terms are satisfied. Source code licensed under a proprietary license can only be shared if proprietary license permits.
- 27. Sharing Open SourceSoftware within the Commonwealth Agencies can share source code for open source software subject to the terms of the license under which it was obtained. – Some open source licenses allow for portions of open source code to be included within proprietary software which may as a result prohibit interagency sharing. Always refer to the terms of the license before considering sharing open source software within your organization.
- 28. Additional Note onSharing Software: Agencies can share source code for software that they own, based on a careful, documented determination regarding ownership. Agencies should not share software until agency counsel has reviewed the legal status of the software that is to be shared.
- 29. Best Value Procurement Executive Department agencies must engage in best value competitive procurement for procurements over certain dollar amount. Best value would require you to assess all of the risks and benefits surrounding software acquisition.
- 30. Online Resources forBest Value Procurement The Commonwealth has announced new standards for information technology acquisitions. The new policy is described in three related documents that can be accessed through the links below: – The Commonwealth‘s Open Standards policy: http://www.state.ma.us/itd/openstandards.htm – The Commonwealth‘s IT Acquisition policy: http://www.state.ma.us/itd/ITAcquisitionPolicy.htm – The Commonwealth‘s Technical Reference model: http://www.state.ma.us/itd/techrefmodel.htm
- 31. Take Home Message: Before embarking on use of open source products: – Educate your staff about the difference between proprietary, open source, and freeware software; – Educate yourself about the legal, business and technical risks involved in using open source software, and balance them in making a business decision as to what kind of software to use. – Procure for best value, taking into account the risks and benefits of using proprietary vs. open source software along with other business and technical best value criteria
