Dear Roy,
several months ago I looked for a way to describe rendered regions within the DART project (poster P3.14 at ADASS 2007), in particular for the XMM-LSS survey master catalog site [1]. More or less I was looking for a rendered regions model (in XML) and a service interface to recover them (using HTTP GET, SOAP or whatever).
At that time the VOTable STC sub-format [2] (from Aladin group) wasn't a VO standard yet and the only alternative was the JHU footprint service (Budavari et al.) that provided a native serialization format and the STC serialization format.
Then I thought to build up a new rendered regions format [3] extending the STC schema (by A. Rots) just for the DART project in order to suite my needs.
Unluckily I've not had time to improve the development of this rendered regions service with a prototype within the DART project, and since then a great work has been done by the Aladin team et al. By now, I think that for a future development of DART I'll adopt the VO standard [3], but for the sake of discussion, I present you my work in this mail.
What you can find there [3] are:
Best regards.
Luigi
