Data Knowledge Base
About the Knowledge Base
The CalHHS Data Knowledge Base is composed of three main parts. These have historically been siloed documents, however, have now been published together to serve as a point of truth guide for all CalHHS data sharing needs.
Governance and Updates
As a product, the Knowledge Base is maintained by the Center for Data Insights and Innovation. It will be reviewed at least annually to ensure base functionality, such as no broken links, etc. For questions or contribution suggestions, please email [email protected]. Each section or component of the knowledge base will have its own governance, update cycle, and contact information. Please see below.
CalHHS Data Sharing Guidelines
The Data Sharing Guide was created in 2024 by the CalHHS Office of Technical Systems Integration (OTSI). The content of the previously published CalHHS Data Playbook and Data Playbook-Beta has been merged with this new sharing guide. If you have questions or ideas to contribute to the Data Sharing Guidebook section, please email [email protected].
CalHHS Data De-Identification Guidelines
The Data De-Identification Guidelines (DDG) Edition 2.0 published here are the most recent guidelines approved by the CalHHS Agency. Each Department or Office within CalHHS will publish its own version of the DDG based on CalHHS DDG Edition 2.0.
The Agency Data De-Identification Guidelines were developed by an interdepartmental DDG Peer Review Team. Find more information on the DDG Governance page.
For Department-specific data questions, please contact that Department directly. This CalHHS webpage has links to the CalHHS Department Specific DDG.
CalHHS Open Data Handbook
The Open Data handbook is a resource with its audience being the CalHHS ODP+GIS Workgroup and those that publish or utilize the CalHHS Open Data Portal. As of February 2025, revisions are being made to the ODP handbook. Please see the ODP Governance page for more information. If you have questions or ideas to contribute to the Open Data section, email [email protected].
