This chart identifies a range of Open Source SOFTWARE licenses that are available and the issue of rights that can be granted. We’ve begun to set up a table to compare the differences and, ultimately, to understand what the benefits are from each type of license.  This slide offers an preview into some of the licenses available for us and how they are in use currently with developers.  This chart is not yet complete.  There are a whole host of issues and rights associated with database licensing that we are looking into, as well as continuing to explore other types of licenses.

I’m not sure if everyone is familiar with these licenses or these questions regarding rights.  We’ll be developing a report that explains these for our community that should be available in about two months.  To a certain extent, we’re interested in gaining your feedback in this session to understand your concerns and questions before we finalize our analysis and our report.

With that in the background, the rest of our panel presenters will discuss how Open Data and/or Open Source has worked for their programs and agencies.
