---++ Collaborative Page for SIA Interface

The Simple Image Access (SIA) interface defines a protocol for
retrieving image data from a variety of astronomical image repositories
through a uniform interface.  The interface is meant to be reasonably
simple to implement by service providers.  A query typically defining a
rectangular region on the sky is used to query for candidate images.
The service returns a list of candidate images formatted as a
VOTable.  For each candidate image an access reference URL may be used
to retrieve the image.  Images may be returned in a variety of formats
including FITS and various graphics formats.  Referenced images are
often computed on the fly, e.g., as cutouts from larger images.

The current working draft for the legacy SIA V1.0 interface can be found
[[http://www.ivoa.net/Documents/latest/SIA.html][here]].

A major update to the SIA interface, SIA V2.0, is in the planning stages.  An analysis discussing the [[http://www.ivoa.net/internal/IVOA/SiaInterface/SIA-V2-Analysis.pdf][Scope and Concepts of SIAV2]] is available for review and comment.
