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 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 Dublin Core metadata terms are a set of vocabulary terms that can be used to describe resources for the purposes of discovery. The original set of 15 classic [33] metadata terms, known as the Dublin Core Metadata Element Set [34] are endorsed in the following standards documents: IETF RFC 5013 [35] ISO Standard 15836-2009 [36] NISO Standard ...
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).
All of these are types of preservation metadata. Preservation metadata therefore supports activities intended to ensure the long-term usability of a digital resource. [3] In the early 2000s it became clear that a shared community metadata standard was needed to ensure long-term preservation of the ever-increasing digital resources.
This was a response to communities whose metadata needs required additional detail. [11] In 2012, the DCMI Metadata Terms was created using a RDF data model. [12] This expanded element set incorporates the original 15 elements and many of the qualifiers of the qualified Dublin Core as RDF properties.
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.

Metadata publishing is the process of making metadata data elements available to external users, both people and machines using a formal review process and a commitment to change control processes. Metadata publishing is the foundation upon which advanced distributed computing functions are being built.
