Metadata elements grouped into sets designed for a specific purpose, e.g., for a specific domain or a particular type of information resource, are called metadata schemas. For every element the name and the semantics (the meaning of the element) are specified.
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).
Metadata schemata can be hierarchical in nature where relationships exist between metadata elements and elements are nested so that parent-child relationships exist between the elements. 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 ...
The PRISM specification defines a set of metadata vocabularies. PRISM metadata may be expressed in a different syntax depending on the specific use-case scenario. Currently PRISM metadata can be encoded XML, XML/RDF, or as XMP. Each of these expressions of PRISM metadata is called a profile. Profile 1 is for the expression of PRISM metadata in ...
Every level requires that the DACS metadata elements from the previous levels are complete, and that the relationship between the current level and previous levels are clearly presented. [10] The rest of Part I defines the metadata elements required for each level of description.
They are focused on data elements which provide measures and metrics for fiscal reporting. Standards such as the ISO/IEC 11179 Metadata Registry specification give guidelines for creating precise data element definitions. Specifically chapter four of the ISO/IEC 11179 metadata registry standard.
facilitate the identification and specification of the metadata elements required to describe a learning resource by providing metadata elements and their attributes; support search, discovery, acquisition, evaluation, and use of learning resources by learners, instructors or automated software processes.
A type of structural and metadata encoding system using an XML Document Type Definition (DTD) was the result of these efforts. The MoAII DTD was limited in that it did not provide flexibility in which metadata terms could be used for the elements in the descriptive, administrative, and structural metadata portions of the object.
