Image Data Model Effort

The Image Data Model, currently under development, will describe multdimensional image and image cube datasets and instances. It will serve as the basis for the description of Image datasets in archives and VO queries, as well as the basis for Image data access protocols such as SIAV2 and related access methods such as siav2.accessData.
