Proposals are discussed either:

1. on the github issue site
2. during the workgroup meetings
3. or on the OHDSI Forum for CDM Builders

Proposals were previously submitted at the CDM and Vocabulary Development. From 7/11/2017 forward they are submitted as issues on the CDM github

Every proposal needs:

• An owner
• Details
• Use cases, analytical questions
• Exploration of the state of the field, other implementations-
• Importance, also with respect to other projects
• Consequences of doing it and not doing it including technical (e.g. implications on vocab, existing software), resources

Github issues are written in a form of markdown different from this wiki so please use this template as a guide.

Proposals are vetted by a group of experts.

If not ready it is returned back to discussion.

Results of vetting:

• Impact
• Priority/Need or not needed
• Alternative solution
• Whether it is a Minor or Major release, or Experimental to be reassessed

• At workgroup meetings by a majority vote
• Determine time of release

• The change should be accompanied by documentation and conventions including use cases
• The change should be demonstrated to the community
