ISO/IEC 11179 Standard describes the metadata and activities needed to manage data elements in a registry to create a common understanding of data across organizational elements and between organizations. ISO/IEC 19506 [41] Software Systems: ISO/IEC 19506 Standard called Knowledge Discovery Metamodel is an ontology for describing software ...
Stores data elements that include both semantics and representations; Semantic areas of a metadata registry contain the meaning of a data element with precise definitions; Representational areas of a metadata registry define how the data is represented in a specific format, such as in a database or a structured file format (e.g., XML)
The result of this is a catalogue of sorts, in which related data element concepts are grouped by a high-level concept and an object class, and data elements grouped by a shared data element concept. Strictly speaking, this is not a hierarchy, even if it resembles one. ISO/IEC 11179 proper does not describe data as it is actually stored.
The Asset Description Metadata Schema (ADMS) is a common metadata vocabulary to describe standards, so-called interoperability assets, on the Web. Used in concert with web syndication technology ADMS helps people make sense of the complex multi-publisher environment around standards and in particular the ones which are semantic assets such as ...
An example of a hierarchical metadata schema is the IEEE LOM schema, in which metadata elements may belong to a parent metadata element. Metadata schemata can also be one-dimensional, or linear, where each element is completely discrete from other elements and classified according to one dimension only.
Metadata management goes by the end-to-end process and governance framework for creating, controlling, enhancing, attributing, defining and managing a metadata schema, model or other structured aggregation system, either independently or within a repository and the associated supporting processes (often to enable the management of content).
The metadata standard is an application profile of the Dublin Core Metadata Element Set and consists of mandatory, recommended and optional metadata elements such as title, date created and description. The e-GMS formed part of the e-Government Metadata Framework (e-GMF) and eGovernment Interoperability Framework (e-GIF).
A database catalog of a database instance consists of metadata in which definitions of database objects such as base tables, views (virtual tables), synonyms, value ranges, indexes, users, and user groups are stored. [1] [2] It is an architecture product that documents the database's content and data quality. [3]
