[OGSA-BES-WG] BES question

[Michel Drescher]

Hi all,

I would suggest the following WRT the current discussion.

Regardless whether the issued EPRs are WS-Names or not. If desired (e.g for
debugging), the batch sub system's job id would be best placed in the EPR
metadata section as the ReferenceParameeters are certainly meant opaque to
anybody else except the issuer and the addressed service instance itself.

A human-readable job id, e.g. user-issued in a portal, is probably best
stuffed into the EndpointIdentifier in a WS-Name - if this is not
abailable, then a RNS service would be a natural fit to map human-readable
names to job EPRs.

Cheers,
Michel
