Abstract

Provided is a method, system, and program for providing an object discovery agent (ODA) client. There is one object discovery agent (ODA) client and at least one ODA, wherein each ODA is associated with one application and includes: (i) application programming interfaces (APIs) to communicate with the associated application to discover definition information on objects maintained by the application and (ii) code to communicate with the ODA client. The ODA client communicates with one of the at least one ODA to cause the ODA to gather definition information on at least one object used by one application. The gathered object definition information is provided to an integration server to integrate the object in an environment including heterogeneous objects from different applications.
