HUD has recently released the 2017 HMIS Data Dictionary, which documents the requirements for the programming and use of all HMIS systems and comparable database systems, effective October 1, 2017. HMIS software must be able to collect all the data elements defined within this HMIS Data Dictionary, support the system logic, including dependencies, identified in the document, and ensure that the data collection and the visibility of data elements is appropriate to the project type and federal funding source for any given project.
This release of the HMIS Data Dictionary supersedes the previously released 2016 HMIS Data Standards Data Dictionary Version 5.1. The 2016 versions of the HMIS Data Dictionary, Data Entry for HMIS Critical Data Standards Changes, and Data Mapping Instructions are still available on the HUD Exchange and can be found in the HMIS Data Dictionary resource abstract. Mapping instructions for the 2017 Data Dictionary will be available soon, so check back.
If you have questions about the data dictionary, please submit them through the HUD Exchange Ask a Question (AAQ) portal. On Step 2 of the question submission process, select “ HMIS” in the “ My question is related to” dropdown. |
