7 Copyright OpenLogic 2006 Compliance Concern 7 Mobile Apps Arent Consistently Complying with Open Source Licenses

8 Copyright OpenLogic 2006 Research Methodology Scanned 635 Top Apps with OSS Deep Discovery 123 Android Apps 512 iOS Apps Picked top paid and free apps across categories Identified 68 Apps with GPL, LGPL or Apache 52 with Apache 16 with GPL/LGPL Examined those apps for compliance with key obligations 8

9 Copyright OpenLogic 2006 Four Areas of Compliance Analyzed 9 Apache GPL/LGPL Provide copy of license Notices/Attributions Provide copy of license Provide source code

10 Copyright OpenLogic 2006 Failure to Comply 10 71% of Apps using Open Source under GPL, LGPL and Apache do not comply Comply 29% Do Not Comply 71% Source: OpenLogic Mobile Research 3/2011

13 Copyright OpenLogic 2006 Three Reasons to Comply 1.Its the right thing to do 2.Protect your IP 3.Money in your pocket 13

22 22 OK, OK I get it.

23 Copyright OpenLogic 2006 How to Become A Good Open Source Citizen 1.Understand open source licensing 2.Create an open source policy 3.Track all open source usage 4.Conduct a scan or audit of your code 5.Develop a compliance checklist 23

24 Copyright OpenLogic Understand OSS Licensing Official definition of OSS license Approved by the Open Source Initiative (OSI) Currently over 60 approved licenses Key Criteria Free distribution Source code is available Derived works are allowed Non-discrimination

25 Copyright OpenLogic Categorizing Open Source Licenses Strings Attached Liberal No Strings Copyleft Additional Clauses Traditional Open Source MIT/X W3C Original BSD Apache Software License Eclipse Public License GNU GPL GNU LGPL GNU GPL v3 Common Public License Mozilla Public License SISSL IBM Public License

26 Copyright OpenLogic Dependency Issues Impact Licensing OSS often depends on or bundles other OSS Need to look at all the dependencies and bundled projects and their licenses Important: The licenses may not be the same! Example: Geronimo (Apache license) uses MySQL (GPL) through the MySQL driver (formerly LGPL but now GPL)

27 Copyright OpenLogic Create an Open Source Policy Things to include Licenses allowed Approval processes Audit and compliance processes Considerations Keep it lightweight Dont let fear guide you 27

28 Copyright OpenLogic Track all Open Source Usage: Why? Know what you are using Best practices for software asset management Identify opportunities for sharing or savings Find out what open source is being used so you can leverage expertise, support, etc. across teams Legal & compliance Validate that you are complying with licenses Be able to determine impact of license changes Provide an audit trail for regulatory compliance Assess impact of lawsuit or IP infringement Maintenance Be prepared to handle security patches or critical issues Able to plan for maintenance updates Support Understand level of support necessary Share support resources (whether internal or external)

29 Copyright OpenLogic Track all Open Source Usage: What? What open source packages are used What versions are used The exact source/object code Where you got it from (source) What license its under What applications its used in What machines they are used on What operating system they are used with Whether the project is internal, external or for distribution When distributed and to whom Approval trail – who approved, when approved, for what purpose

30 Copyright OpenLogic Conduct a scan or audit of your code Outcome of an OSS audit: List of open source packages List of open source licenses List of license obligations List of licenses that may have conflicting terms Options Scanning tools Manual review Audit services

31 Copyright OpenLogic Develop a compliance checklist Create a compliance checklist: Notices in code and/or documentation Source code provided in proper way Is there an EULA for your product? If there are conflicts or compliance is not possible: Can you live without this code? Is there an alternative to the code? Can you contact the author and ask for an exception/different license? Risk management: What is likely to get litigated? What are your sticking points that prevent perfect compliance?
