A specification by ASTM that is intended to be used for summary/continuity of care documentation. A CCM is a type of EMR.

An IT system that creates, stores, and manages EMRs.

The collection of all EMRs of a single patient, across organizational and national boundaries.

The medical record or records of a single patient in the IT system of an actor (health provider, government entity, payer, etc.). In this definition, an HDR is a type of EMR.

A profile of the medical content of an HDR. An HCP is specified separately from the HRF. The hData Project defines an initial HCP (iHCP) that covers the 35 data elements for EHRs/EMRs defined by the National Quality Forum.

A single instantiation of the HRF.

The part of the hData specification that defines the abstract hierarchy, meta-data schema, and document organization of the hData record.

The part of the hData specification that defines the basic HTTP-based API for accessing or modifying an HDR.

A normative specification that defines the HRF, the HRA, and a file-based serialization format.

A constrained profile of the CCD that is intended to simplify implementation and improve interoperability. There is no normative schema for C32. Note that HITSP has recently split up C32 into HITSP/C80 and HITSP/C83.

A significantly constrained profile of the C32 specification. L32 comes with a normative schema and can be mapped onto the HRF.
