Hot Topic: DMIM

This is a revisit of a discussion held at the last WGM. There is some disagreement between MnM and Publishing about the need for a DMIM for every domain. Several committees have subject areas with contents that do not all fit well in a single DMIM. Examples include "shared messages", "public health", "clinical decision support", and "patient administration". We don't want the RIM to be a DMIM for these committees. Domains are currently both "semantic things" and "publishing things". We currently have some limitations due to publishing infrastructure/tooling. There was a common desire to have the semantic and publishing aspects of this problem disentangled. We want the notion of a "body of content" in an HL7 standard to be coherent and derived from common models.

There was a general concensus that changing the identifier of an artifact should not be regarded as substantive. Some felt that a move to non-meaningful identifiers would be useful.

We need to separate the maintenance of semantic domains from the maintenance of publishing topics.

Gregg asked when the tooling for publishing could support levels of models as the MIF does? Woody suggested that this would probably be about 18 months out.
