OGSA v 2 Definition Process “top down” and “bottom up” worlds are to be coordinated § OGSA-WG is concerned with defining requirements and overall architecture: the lighthouse towards which others may steer. § WGs within GGF or other bodies may/will be formed to develop specifications that speak to requirements identified by OGSA-WG. § The steps by which a technical specification may become identified as “OGSA compliant” remains to be clearly defined. • A key requirement might be identification as a “recommendation” in the sense that there are two or more interoperable implementations.
