---+!! 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:

<blockquote>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.</blockquote>

---++ Status
   * SimpleDALRegExt is currently in [[http://wiki.ivoa.net/twiki/bin/view/IVOA/SimpleDALRegExt10RFC][TCG Review]] period: Dec 2012 - January, 2013
   * Two major changes were incorporated into the latest draft as a result of the [[InterOpOct2011][Oct 2011 Interop]]: 
      * recommended prefix changed from ==ssa== to ==ssap==
      * re-added ==&lt;supportedFrame&gt;==
The details can be reviewed in this [[http://www.ivoa.net/forum/registry/2011-October/004809.html][follow-up report]]

<!--
   * The working short name for this effort is now *SimpleDALRegExt*.  (This was changed from *RegSimpleDAL* during the [[InterOpMay2010][May 2010 Interop]].)  
   * Development of the spec document is now underway via the [[http://code.google.com/p/volute/][volute]] google code repository.  You can find it under [[http://code.google.com/p/volute/source/browse/#svn/trunk/projects/registry/RegSimpleDAL][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 [[http://code.google.com/p/volute/][volute]] google code repository under [[http://code.google.com/p/volute/source/browse/#svn/trunk/projects/registry/tools][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?

-- IVOA.MarkusDemleitner - 18 May 2011

_The suggestion was incorporated into the latest draft._
