Sergio Fernández gave a presentation on Marmotta, an open platform for linked data. He discussed Marmotta's main features like supporting read-write linked data and SPARQL/LDPath querying. He also covered Marmotta's architecture, timeline including joining the Apache incubator in 2012, and how its team of 11 committers from 6 organizations work using the Apache Way process. Fernández encouraged participation to help contribute code and documentation to the project.

7. Timeline
● Dec 2012: joined ASF Incubator
● Apr 2013: release 3.0.0-incubating
● Sep 2013: release 3.1.0-incubating
● Oct 2013: graduation?

9. Team
11 committers
6 organizations
7 nationalities

10. How we work: the Apache Way
● community over code
● meritocracy organization
● communication in the mailing list

11. Contributing
there is a fairly obvious path:
1. be familiar with the Apache Way, especially about
meritocracy
2. participate in the mailing lists and help (often
more important than writing amazing code)
3. write code, add patches, unit tests and
documentation
In the earlier stages of the project, the bar is a bit
lower, so it pays to join early!
