Metadata management simplifies the way people and programs find and use data. Healthcare has a fundamental requirement for describing the meaning, provenance and governance of data, and for setting standards for how that data is stored and communicated. It uses metadata registries and repositories (MetaRep) extensively for a wide range of purposes supporting care delivery, reporting and research.
ISO/TS 21526 describes requirements for collections of metadata about data elements and their containing models and datasets in a healthcare environment. The collection can serve as a repository or as dictionary describing a set of items in use in a particular domain, organization or product for reference, or it can additionally serve as a registry, supporting the development and communication of standard items to an audience with shared goals.
ISO/TS 21526 specifies standard refinements that account for the detailed governance and administration requirements that are particular to healthcare data. It focuses on the description of data that is persisted in healthcare systems rather than the specification of messages between these systems.
ISO/TS 21526 on healthcare MetaRep is useful for:
Data in healthcare systems should persist in content and meaning across organizations and time for a wide variety of uses including patient care, patient safety, service management, service improvement, public health, and healthcare research.
ISO/TS 21526 supports an ecosystem of interoperable registries and repositories which facilitate both the development and implementation of content standards and thus interoperable content and the publication of interoperable metadata about the kinds of data available in both care and research.
ISO/TS 21526 provides you with a modular approach to the registration of metadata about a wide variety of models and the management of that registry. MDR Metamodel consists of two distinct components: common facilities defining metadata about content, metadata objects, with attributes for identification, naming, definition, classification, conceptualization, administration, and registration; and those defining content models for some of the metadata objects to be registered concept systems, value lists and data elements.
