HUD has recently released the 2017 HMIS Data Dictionary Version 1.3. This release of the HMIS Data Dictionary supersedes the previously released 2017 HMIS Data Standards Data Dictionary Version 1.2. Version 1.3 contains several minor revisions that provide further clarification for users.
The 2017 HMIS Data Dictionary provides the requirements for the programming and use of all HMIS systems and comparable database systems. 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 access to data elements is appropriate to the project type and federal funding source for any given project.
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. |
