Dig This: Oracle Integration Repository
By oracletechnet on Mar 22, 2006
Architects, take note: Oracle has published a massive API repository containing business service endpoints for E-Business Suite - for Payables, Marketing, HR, Procurement, you name it.
Over time this repository (which will ship with EBS Release 12) will include PSFT and JDE endpoints as well (no word on Siebel as of yet).
Combined with BPEL Process Manager, this should be a useful tool for architects exploring or implementing SOA.
