# Data Standards

This page is a place holder for a data standards page/set of data standards pages similar to MC2 Center Data Model. The HTAN version of the MC2 tables will include additional columns such as "required_if_component" and "required_if_value". Until the new pages are constructed, please see the information on the Data Standards page of the HTAN Data Portal.

Note

Once these pages are added, the Data Standards page will be removed from the data portal. All links to "Data Standards" throughout this manual will need to be updated.
