Abstract

The purpose of this note is to propose extensions of the SIAP protocol (http://www.ivoa.net/internal/IVOA/IvoaDAL/ACF8DE.pdf) in order to allow some kind of structured description of metadata for images or observations provided by an image server or an observation archive. One main requirement for that is to allow VO tools to use this extension protocol as the Data Access Layer for metadata trees, intended for hierarchical display of observation metadata like in the AVO prototype. In the same time we are looking for backward compatibility with SIA.
