[Building Sakai] Custom POST Entity Broker

[Steve Swinsburg]

Hi Paul,

Would you be interested in contributing your entity provider to the core of Sakai? It would be very useful. If so, just add any relevant files (or ideally a patch) into a Jira. If you assign it to me I can take a look.

cheers,
Steve
