[OSGeo-Standards] distributed image processing support?

[Michael P. Gerlek]

I'm increasingly seeing more and more need for an open framework for
doing image processing in a distributed, batch-oriented manner.  I'm
thinking along these lines:

  - ability to reference some input image data
  - ability to reference some output repository
  - ability to specify a processing operation, e.g. mosaic, reproject,
balance, etc
  - ability to monitor job progress

I know a couple companies who have systems that do some things like
this, but all are proprietary and nothing's very generalized yet.  I
know too of OGC's Web Coverage Processing Service (WCPS), but I don't
think it has achieved any adoption at this point, and in any case I'm
looking for something that can be worked on in the open (and ideally
more RESTful).
