harmonization meeting to occur between working group meetings. In scheduling the meeting, consideration is given to allow sufficient notice to potential attendees, to allow at least 30 days review of posted change proposals, and at least 30 days to apply and document accepted changes to RIM.

• Any HL7 member may attend the RIM change proposal harmonization meeting. Modeling facilitators and at least one steward representative per Technical Committee are encouraged to attend the meeting. Representatives from other ANSI or ISO accredited organizations are welcome to attend the harmonization meeting to introduce and discuss change proposals they have submitted.

• The co-chairs of the Modeling and Methodology Technical Committee facilitate the meeting. The sponsor of a RIM change proposal should be present to introduce, discuss, and answer questions concerning the proposed change. If the sponsor is not able to be present, it may designate a proxy to introduce the change or a representative from one of the affected steward committees may introduce it; otherwise the proposal is tabled.

Disposition of change proposalDisposition of change proposal

• Discussion of a proposal may lead the representative from the sponsoring committee to revise, table, or withdraw the proposal. Proposals that are neither tabled nor withdrawn are put to a vote. There is one vote per Technical Committee. To approve a change proposal that is supported by the affected steward committees requires a simple majority. To approve a change proposal that is opposed by an affected steward committee requires a 2/3 majority for approval.

• Approved changes are applied to the RIM. Tabled changes may be re-introduced at a subsequent harmonization meeting. Rejected and withdrawn changes are returned to the sponsoring committee with comment. The disposition of all changes is noted on the change proposal. Notes from the harmonization meeting summarize the discussion and disposition of each RIM change proposal.

• A RIM change proposal may lead to revision of the MDF. Approved RIM changes which introduce new attribute types or data types will require updates to the MDF, as will approved changes which lead to the addition, revision, or removal of a style guideline.
