Perdikeas, M. 2014-12-04 1.0 IVOA Registry WG registry@ivoa.net Virtual observatory Database Registries provide a mechanism with which VO applications can discover and select resources - first and foremost data and services - that are relevant for a particular scientific problem. This specification defines an interface for searching this resource metadata based on the IVOA's TAP protocol. It specifies a set of tables that comprise a useful subset of the information contained in the registry records, as well as the table's data content in terms of the XML VOResource data model. The general design of the system is geared towards allowing easy authoring of queries. http://www.ivoa.net/documents/RegTAP Other Research 1.0 1.0 The data model for the tables making up the relational registriy in version 1.0. This key is used to locate TAP services implementing RR in TAPRegExt dataModel elements. 1.1 The data model for the tables making up the relational registriy in version 1.1. This key is used to locate TAP services implementing RR in TAPRegExt dataModel or VODataService schema/@utype elements.
