StandardsRegExt: Describing Standards for Registries

Note:

This standard is formerly known as VOStandard; discussion of the standard has moved here.

The version 1.0 registry data model uses Resource Identifiers in several places to identify which standard a particular resource follows (e.g. the capability element's standardID attribute). The Identifiers spec requires that any IVOA ID must have an entry in an IVOA registry; this implies that the standard itself is registered. Furthermore, there is an increasing interest to use IVOA identifiers to identify concepts and properties (e.g. VOSpace); the underlying identifier thus must be registered as well. The VOStandard data model and schema provides a framework in which IVOA standards can be described in the registry.

The goals of this extension are:

• allow support for an IVOA standard be recognized via an IVOA identifier (e.g. as in standardID)
• allow users to discover documentat about a standard protocol via the registry (in particular, via records of instances of the standard).
• allow one to define and use IVOA identifiers to identify a concept or property.

This document is approved for Recommendation.

Latest materials

• Recommendation on May 8, 2012
  • see results of RFC
  • The TCG review produced a proposal to add a <schema> element, resulting in the 17 Feb 2012 version; this change was subsequently approved by the TCG after posting to the registry list.
• schema document: StandardsRegExt-v1.0.xsd as of May 8, 2012

Samples

siastd.xml

This defines the SIA standard, defining its URI as ivo://ivoa.net/std/SIA. It enumerates the parameters that defines the standard SIA interface.

complang.xml

This defines a set of keys representing different computer languages. For example, the Python language can be identified via the URI, ivo://ivoa.net/std/application/languages#Python.

vospacestd.xml

This defines the VOSpace standard, defining terms mandated in the VOSpace specification like ivo://ivoa.net/vospace/core#httpget.

StandardsRegExt.xml

This defines the StandardsRegExt standard and includes the proposed <schema> element.

Status
