Hi Enric,
You're essentially correct. WSRF has no "builtin" resource enumeration function, as this would be a higher level system-like function.
For a link between WBEM/CIM and WSRF, please see the document at: http://www-128.ibm.com/developerworks/webservices/library/specification/ws-w sdm/ It is the proposal to map CIM onto WSDM (Web Services Distributed Management). WSDM, to put (a bit too) simply, is a layer on top of WSRF/WSN, and even if you only don't know WSDM you might be able to understand a lot of the document (see section 11 and especially section 16). This document might give you an example of what kind of thing is the "higher-level" that David talked about, and "WS-CIM" that Tom mentioned. Hope that helps, Fred Maciel Hitachi America R&D
