OGSA-DMI conference call notes ============================== 28 February 2007 Participants ------------ Allen Luniewski, IBMM Michel Drescher, Fujitsu Monutes: Michel Drescher 1) Early discussion ------------------- - 21 Feb 2007 notes approved without changes 2) Factory concerns ------------------- - Allen summarises and clarifies his concerns regarding the definition / specification of the OGSA-DMI Factory and its implementability while retaining interoperability - Michel reiterates the contents of his lates answering mail (http://www.ogf.org/pipermail/ogsa-dmi-wg/2007-February/000140.html) and clarifies ambiguous passages - Allen and Michel consent that negotiating a data transfer protocol is a crucial part of the OGSA-DMI Factory - Allen and Michel agree that OGSA-DMI needs to define information items that convey specific information about supported protocols for source and sink. -- However, the Functional Specification does not specify the infrastructure or means how this information is conveyed from source and sink to the OGSA-DMI Factory. This is punted to the concrete binding specification that defines exact formats and operatione to use for which infrastructure standard (e.g. WS-ResourceTransfer, WS-I 1.1 Base Profile, OGSA WSRF Base Profile 1.0, etc) - Allen and Michel discussed a possible means for WS-I to mandate that the WS-Addressing EndpointReferences that model source and sink must include the supported data transfer protocols encoded in the EPR's metadata section. - An alternative approach would be that the WS-I binding specification mandates support of a specific operation on the source and sink. 3) Functional Specification --------------------------- - The functional Specification has not been discussed other than potential inclusion of information discussed on today's call. 3) Wrap up ---------- - No discussion.
