12. Three steps: Try it out, submit bugs you find Suggest/Implement your improvements Become a contributor and submit improvements http://ondex.sourceforge.net Contributors will be acknowledged on the project website and in publications involving their work. Contributors are welcome to publish their work on ONDEX under their own names. How to contribute

13. Good : Write Flatfile parser for ONDEX Better : Provide your database in OXL (see Taubert et al. (2007) “Exchange of integrated datasets – the OXL format”, in press, IB2007) Also welcome : Provide your database in another standard (BioPax, SBML, XGMML; but may result in loss of information) http://ondex.sourceforge.net What to contribute

14. Algorithms : Needed for the alignment of integrated data Core : Improve persistency layer of Ontology based graph Exporter : Provide your own exchange standard Webservices : Increase compatibility http://ondex.sourceforge.net What to contribute

15. http://ondex.sourceforge.net Support : OXL in your application Connect : Import from web service or directly from Core API Algorithms : Graph analysis using the ONDEX Visualisation and Analysis Tool Kit (OVTK) Feedback & Feature requests : Mailing lists and Sourceforge.net What to contribute
