Subject: Re: [soa-rm-ra] Updated Visual Model for Service Description
I am thinking in terms of federation at the granularity of general description only, no finer than that for the moment. The following statements are from the implementaton side of things. As part of the general description, a user can select federations they want the description to belong to. The selection of federations are controlled through certificate associations. Everyone who wants to add a description to the ebXML/UDDI registry either has or is issued a certificate. I have not worked through the implementation details yet but it is something along those lines. I think the Service Description needs to identify meta-data that allows it to be governed in social structures as described in Section 3.4.6, Governance and Social Structures. What I am suggesting is that federations is a description meta-data element that is a tie to section 3.4.6.
