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.
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 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.

In 2001–2002 the PMF working group outlined the types of information that should be associated with an archived digital object. Their report, A Metadata Framework to Support the Preservation of Digital Objects (the Framework), proposed a list of prototype metadata elements. At this stage these proposed elements could not be implemented and ...
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 ...
This information is described as metadata by the standard. Begun in 1995, [1] the effort brings together data professionals from around the world to develop the standard. The DDI specification, most often expressed in XML, provides a format for content, exchange, and preservation of questionnaire and data file information. DDI supports the ...
