IVOA Recommendation: VOResource: an XML Encoding Schema for Resource Metadata Version 1.03

TL;DR

This paper introduces VOResource, an XML schema standard for resource metadata in the Virtual Observatory, enabling interoperable resource discovery and description across diverse applications.

Contribution

It defines a comprehensive XML encoding schema for IVOA resource metadata, supporting extensibility and interoperability in resource registries.

Findings

Standardizes resource metadata description in XML

Supports extensibility for new resource types

Facilitates interoperable resource discovery

Abstract

This document describes an XML encoding standard for IVOA Resource Metadata, referred to as VOResource. This schema is primarily intended to support interoperable registries used for discovering resources; however, any application that needs to describe resources may use this schema. In this document, we define the types and elements that make up the schema as representations of metadata terms defined in the IVOA standard, Resource Metadata for the Virtual Observatory [Hanicsh et al. 2004]. We also describe the general model for the schema and explain how it may be extended to add new metadata terms and describe more specific types of resources.
