Documentation for Integration Repository Interfaces

I'm looking for an on-line source for the integration respository interfaces - similar to the now deprecated Interface Repository (IFR)(http://ifr.sap.com).

In particular, I'm looking for the WSDL/XML and Java Proxy interfaces for the following BAPIs.

- BAPI_CUSTOMER_GETDETAIL or BAPI_CUSTOMER_GETDETAIL1

- BAPI_CUSTOMER_CHANGEFROMDATA

- BAPI_SALESORDER_GETSTATUS

- BAPI_SALESORDER_CHANGE

Does anybody know if those interfaces are available online anyplace?

Thanks,

Mark
