Hi,
Been looking at the ontology module as it might be useful in my day job.
I tried parsing the latest GO flatfile at http://geneontology.org/docs/download-ontology/#go_basic and the parser handles it OK (ie it doesn't crash). But with the low number of tests, documentation and sample code it's hard to be confident that it's parsing everything correctly for use in production system.

Would it be worth giving this module a bit of attention? Specifically

• enhancing test coverage especially w.r.t supporting OBO spec
• improving Javadoc and sample code
• adding a README to the project
• updating code style/formatting and using more modern Java 7/8 idioms (once test coverage is much better)

Also, I'm interested in using Go annotation format files - http://geneontology.org/docs/go-annotation-file-gaf-format-2.2 - is a parser for this something that would belong in this module?

I'd be happy to take a stab at some of these tasks unless there are strong contrary opinions.
