<p>The OMOP Common Data Model is managed by the OHDSI CDM Working Group. If you would like to join our group please fill out <a href="https://forms.office.com/Pages/ResponsePage.aspx?id=lAAPoyCRq0q6TOVQkCOy1ZyG6Ud_r2tKuS0HcGnqiQZUOVJFUzBFWE1aSVlLN0ozR01MUVQ4T0RGNyQlQCN0PWcu">this form</a> and check “Common Data Model” to be added to our Microsoft Teams environment. 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 <a href="http://ohdsi.github.io/CommonDataModel/cdmRefreshProcess.html">here</a>.

<h2>Current CDM Version</h2>
<p>The current CDM version is <a href="http://ohdsi.github.io/CommonDataModel/cdm54.html">CDM v5.4</a>, depicted below. This CDM version was developed over the course of a year by considering requests that were sent via our <a href="https://github.com/OHDSI/CommonDataModel/issues">issues page</a>. 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 <a href="http://ohdsi.github.io/CommonDataModel/cdm54Changes.html">final changes</a> were then delivered to the Community through a new R package designed to dynamically generate the DDLs and documentation for all supported SQL dialects.</p>
