Metadata Encoding & Transmission Standard
The Metadata Encoding & Transmission Standard ( METS ) is an XML format defined with XML schema for the description of digital collections of objects with metadata .
application
In a digital archive , metadata about these objects must be managed in addition to the digital objects. In addition to the object description ( e.g. title , creation date ), this metadata can also contain information about the document in the archive (e.g. which archivist put it in the archive and when ). METS provides a structure for this information.
METS can be used to code hierarchical and otherwise structured works. A work can z. B. a book series , a single book with chapter and page structure or a film with several scenes.
structure
METS is divided into 7 areas:
1 <mets>
2 <metsHdr/>
3 <dmdSec/>
4 <amdSec/>
5 <fileSec/>
6 <structMap/>
7 <structLink/>
8 <behaviorSec/>
9 </mets>
The sections are in detail:
- METS Header metsHdr : Metadata describing the METS document.
- Descriptive Metadata Section dmdSec : The Erschließungs data of the object.
- Administrative Metadata Section amdSec : Administrative information such as the origin of the object, copyrights , information on the storage of the object.
- File Section fileSec : All files belonging to the object.
- Structural Map structMap : Description of the internal structure of the object.
- Structural Links structLink : Contains links between elements, e.g. for archiving websites .
- Behavioral Section behaviorSec : This section can be used to connect executable elements ( e.g. web services ) to the METS package.
In principle, the format of the metadata in the individual sections can be different and is not determined by METS. Different formats can be used in a METS document, e.g. B. MAB , MARC , MODS , Dublin Core , MIX ....
A subset of the XLink scheme is used to link METS files and the digital objects about which statements are to be made .
METS is administered by the Library of Congress . Version 1.11 was adopted in January 2015.
