This working group endeavors to maintain the OMOP CDM as a living model by soliciting and responding to requests from the community based on use cases and research purposes. For more information on the CDM refresh process please see the description [here](http://ohdsi.github.io/CommonDataModel/cdmRefreshProcess.html). You will find information on our meetings and links to join at the end of this page. ## Current CDM Version The current CDM version is [CDM v5.4](http://ohdsi.github.io/CommonDataModel/cdm54.html), depicted below. This CDM version was developed over the course of a year by considering requests that were sent via our [issues page](https://github.com/OHDSI/CommonDataModel/issues). The list of proposed changes was then shared with the community in multiple ways: through discussions at the weekly OHDSI Community calls, discussions with the OHDSI Steering Committee, and discussions with all potentially affected workgroups. The [final changes](http://ohdsi.github.io/CommonDataModel/cdm54Changes.html) were then delivered to the Community through a new R package designed to dynamically generate the DDLs and documentation for all supported SQL dialects. - [Link to DDLs for CDM v5.4](https://github.com/OHDSI/CommonDataModel/tree/v5.4.0) - [Link to ReadMe for instructions on how to use the R package](https://github.com/OHDSI/CommonDataModel/tree/master#readme) ![](images/cdm54.png) ## CDM WG Meeting Information The CDM working group meets the first and third Tuesday of the month.
