VOResource Extensions for Describing SSA, SIA, SLA, and ConeSearch Services
- Note:
- This standard SimpleDALRegExt is formerly known as RegSimpleDAL; discussion of the standard has moved here.
The page tracks the development of the IVOA specification document defining VOResource Extensions for SSA, SIA, SLA, 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 services
that supports four fundemental data access protocols--Simple Cone
Search (SCS), Simple Image Access (SIA), Simple Spectral Access (SSA),
Simple Line Access (SLA)--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.

- The working short name for this effort is now SimpleDALRegExt. (This was changed from RegSimpleDAL during the May 2010 Interop.)
- 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
Comments to current draft
The suggested ssa: prefix for the SSAP extension schema is unfortunate.
This is due to the abuse of xmlns in "binding" the model name
(the thing before the colon in a utype) to a data model URL in the SSA
spec. Withit, in any document that contains SSA utypes (e.g., table definitions
of SSA services), the ssa XML prefix is taken. So -- can we use ssap? Or
ssareg?
-- MarkusDemleitner - 18 May 2011
The suggestion was incorporated into the latest draft.
