Proposal: CDM Schema Revisions

[vojtechhuser]

original request is here: http://www.ohdsi.org/web/wiki/doku.php?id=documentation:next_cdm:schema_revisions

Goal: clearly define schemas at a site using OMOP.

Separate data from results.

@pbr6cornell, @fdefalco:

Is this still active? Remember? You proposed to split the model into the schemas native, CDM and ohdsi. Or has this been superseded by the ATLAS/ARACHNE/WEBAPI/Architecture debates. I am not up to date.

Here is a relevant wiki page:

To clarify - an excerpt from the data architecture wiki:

Source Data : Person level data that is acquired through different parts of the healthcare system. These sources are said to exist in the “native schema”.
Standardized Data : Data that has been converted into the OMOP CDM format. These data are said to exist in the “CDM schema”.
Derived Data : Data that is the result of some form of processing on data that came from the OMOP CDM format. These data are said to exist in the “results schema”. Most of these data are aggregate summary statistics.
OHDSI Platform Metadata : Metadata that is created or maintained to describe a concept, process or system function within the broader OHDSI architecture. These data are said to exist in the “OHDSI schema”.
