A Metadata Structure is a information schema composed of metadata record that describes a dataset.



  • (Wikipedia, 2015) ⇒ Retrieved:2015-6-16.
    • Metadata is “data about data". [1] There are two types of metadata (or two types of “metadata types ") : structural metadata and descriptive metadata. Structural metadata is data about the containers of data. Descriptive metadata uses individual instances of application data or the data content.

      Metadata was traditionally in the card catalogs of libraries. As information has become increasingly digital, metadata is also used to describe digital data using metadata standards specific to a particular discipline. By describing the contents and context of data files, the usefulness of the original data/files is greatly increased. For example, a web page may include metadata specifying what language it is written in, what tools were used to create it, and where to go for more on the subject, allowing browsers to automatically improve the experience of users. Wikipedia encourages the use of metadata by asking editors to add category names to articles, and to include information with citations such as title, source and access date.

      The main purpose of metadata is to facilitate in the discovery of relevant information, more often classified as resource discovery. Metadata also helps organize electronic resources, provide digital identification, and helps support archiving and preservation of the resource. Metadata assists in resource discovery by "allowing resources to be found by relevant criteria, identifying resources, bringing similar resources together, distinguishing dissimilar resources, and giving location information."

    • Metadata is essentially a catalogue record, providing (a) access points by which records of documents can be sorted or retrieved and (b) descriptive information, by which the relevance of a document can be assessed without consulting it in full. Preferred terms or notations selected during the indexing process are commonly applied as metadata elements to describe the subject of a document.

      • In general, "data about data;" functionally, "structured data about data." Metadata includes data associated with either an information system or an information object for purposes of description, administration, legal requirements, technical functionality, use and usage, and preservation. .
