Abstract

During 2003, the National Virtual Observatory (NVO) project in the US set out to prototype the VO Registry framework as described by the IVOA Registry Working Group. A key goal was to demonstrate use of the VOResource XML schemas as a format for exchanging descriptions of resources in registries. While we feel that the effort was overall a successful validation of the framework and the XML schemas, it was particularly useful for understanding where the challenges lie. This document looks at our lessons learned in using the VOResource XML schemas, focusing on what made using the schemas difficult. This document avoids drawing too many conclusions about what should be done to improve the schemas; rather, it is meant to serve as input to a discussion of a possible future revision. We recognize that some of the complexity inherent in the schemas may be necessary to adequately address the needs of the various IVOA projects. However, we do outline broad options for addressing these concerns.
