description: A profile on the DocumentReference resource for MHD with minimal metadata constraints. \r\n- MHD is based on the [IHE Document Sharing](https://profiles.ihe.net/ITI/HIE-Whitepaper/index.html) model, \r\n- the [3:4.1 Abstract Metadata Model](https://profiles.ihe.net/ITI/TF/Volume3/ch-4.1.html#4.1), and \r\n- the use defined here is FHIR DocumentReference implementation of the \r\n- ebRIM implementation at [3:4.2.3.2 Document Entry](https://profiles.ihe.net/ITI/TF/Volume3/ch-4.2.html#4.2.3.2).\r\n- with use-cases and constraints found in [3:4.3 Additional Document Sharing Requirements](https://profiles.ihe.net/ITI/TF/Volume3/ch-4.3.html#4.3)
