[bioontology-support] Java client for BioPortal REST services?

[ben leinfelder]

Hi,
I'm wondering if there are any existing Java clients for consuming the services described here: http://www.bioontology.org/wiki/index.php/NCBO_REST_services
I've poked around the GForge repository (https://bmir-gforge.stanford.edu/gf/project/) for possibilities, but haven't found anything conclusive. 
If I do need to develop my own Java client, are there standard schema for the responses I can get from each service?
Thanks,
