VOResource Extensions for Describing SSA, SIA, and ConeSearch Services

Note:

This standard has a new name: SimpleDALRegExt and, thus, a new page for capturing discussion. Consequently, this page is now deprecated.

The page formerly tracked the development of the IVOA specification document defining VOResource Extensions for SSA, SIA, and ConeSearch Services. The draft abstract is as follows:

An application that queries or consumes descriptions of VO resources must be able to recognize a resource's support for standard IVOA protocols. This specification describes how to describe a service that supports three fundemental data access protocols--Simple Cone Search (SCS), Simple Image Access (SIA), and Simple Spectral Access (SSA)--using the VOResource XML encoding standard. A key part of this specification is the set of VOResource XML extension schemas that define new metadata that are specific to those protocols. This document describes in particular rules for describing such services within the context of IVOA Registries and data discovery as well as the VO Stadard Interface (VOSI) and service self-description. In particular, this document spells out the essential mark-up needed to identify support for a standard protocol and the base URL required to access the interface that supports that protocol.

Status

In brief,

• The working short name for this effort is RegSimpleDAL.
• Development of the spec document is now underway via the volute google code repository. You can find it under trunk/projects/registry/RegSimpleDAL
• During the internal development phase, updated versions will be irregularly posted to this page.
• Ray Plante is targeting a working draft version to be available immediately after the Nov 2009 Interop

Schema-to-Spec Stylesheet

To support this effort, a few people (Harrison, Plante) have author XSL stylesheets to convert XML Schemas into HTML. Ray Plante's efforts have been uploaded to the volute google code repository under trunk/projects/registry/tools. more info coming
