METS format

The mets (Metadata Encoding and Transmission Standard) format is available for books and journal issues (more info about types Document types). The aim of this format is to describe the metadata and the complete structure of the volume (book or journal issue).

The mets format is documented on the Library of Congress website: http://www.loc.gov/standards/mets/.

The list of available records in mets format can be found through OAI: http://oai.openedition.org/?verb=ListIdentifiers&metadataPrefix=mets (use resumptionToken to retrieve the complete list).

In OpenEdition OAI, a mets record is divided into 3 main parts : one mets:structMap, one mets:fileSec and several mets:dmdSec.

1. mets:structMap

The mets:structMap element describes the tree structure of the volume.

mets:div elements are nested to describe the hierarchial organisation of the volume, parts, texts. Each mets:div element is qualified with the following attributes:

  • TYPE: List of document types
  • ORDER: sequence number whitch defines the order of the documents relative to the parent div element.
  • DMDID: refer to the ID of the relevant mets:dmdSec element.
  • LABEL: descriptive label

Each mets:div element refering to a document file have one or several mets:fptr child element, with a FILEID refer to the ID of the relevant mets:file element.

example: http://oai.openedition.org/?verb=GetRecord&identifier=oai:books.openedition.org:puv/2002&metadataPrefix=mets

        <mets:fptr FILEID="F_OB_puv_pdf_2056"/>
    </mets:div>
</mets:div>

2. mets:fileSec

The mets:fileSec (File Section) element is a main element contaning mets:file elements, one for each available format of each document described in the mets:structMap section.

The mets:file element have a child node mets:FLocat with an attribute xlink:href providing the url of the ressource.

Note

mets:structMap/mets:div/mets:fptr/@FILEID match mets:fileSec/mets:fileGrp/mets:file/@ID

example: http://oai.openedition.org/?verb=GetRecord&identifier=oai:books.openedition.org:puv/2002&metadataPrefix=mets

    </mets:file>
</mets:fileGrp>

3. mets:dmdSec

Each mets:div element used in the mets:strucMap is described in a mets:dmdSec (Descriptive Metadata Section) in dcterms. The metadata provided are the same as the metadata provided in QDC format.

The mets:dmdSec have an ID attribute matching the DMDID of mets:div elements available in mets:structMap.

Note

mets:structMap/mets:div/@DMDID match mets:mets/mets:dmdSec/@ID

example: http://oai.openedition.org/?verb=GetRecord&identifier=oai:books.openedition.org:puv/2002&metadataPrefix=mets

Pour la seule année 1867, trente mille esclaves furent exportés du Soudan vers l’Égypte via le Nil ou la mer Rouge, en majeure partie des jeunes filles.
