Difference: ImageDM (6 vs. 7)

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.

ImageDM-ObsCore Convergence

It was agreed in the fall 2013 interop to do whatever is necessary to bring the Image data model into convergence with ObsCore (e.g., ObsTAP), in particular making data models such as ImageDM and SpectralDM extensions of ObsCore, all sharing a common core data model. We are fast-tracking an updated version of both the ImageDM and SIAV2 drafts that will make a first cut at this convergence, sufficient to support ongoing development for the Cube initiative, while further development of the working drafts goes forward. An initial analysis of what is required has been performed by a subset of the ImageDM author group (FB, ML, MCD, DT) and the results are summarized here:

• Initial analysis of ImageDM-ObsCore convergence

• ImageDM and ObsCore Utypes vs Char2 (FB)

Further updates will be posted here as this effort progresses. Discussion should be carried out on the DM mailing list.
