TL;DR
This paper specifies a relational schema for VO registries, enabling efficient discovery of data and services through a TAP-based interface, facilitating easier querying of resource metadata.
Contribution
It introduces a standardized relational schema for VO registries, aligning with the VOResource data model and enhancing resource discovery capabilities.
Findings
Defines a set of tables for registry metadata
Aligns schema with VOResource XML model
Supports efficient resource discovery queries
Abstract
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.
