Data Model Working Group : November 2024

As the IVOA Data Model landscape becomes fuller, we are introducing models which serve overlap in domain space with other models, but are represented at a level appropriate for their target usage. For example, CAOM for archives overlaps with content in Dataset, Characterisation, Cube, etc which are more data product oriented. MANGO introduces an EpochPosition which consolidates elements from the Coordinates model into a compact object suitable for application workflow. This talk is an update on an effort to define a mechanism to formally map the relation between models with overlapping content. The goal is to minimize the effort needed to ensure the consistency this content.
