The University of Waikato Digital Library Group - Greenstone Project METS Profile [Draft]
This profile specifies how METS documents representing digital objects within the Greenstone Digital library software should be encoded. Greenstone is an open source software from the New Zealand Digital Library Project at the University of Waikato (see for more details). Each digital source document is represented in a canonical form that involves two compulsorary XML files plus associated files such as supporting images (optional). One XML file is in METS syntax that describes the potentially nested sections to the document with metadata attached at any section level; the other XML file uses a supporting syntax to represent any text a source document may have, again reflecting the nested sections structure.

A conforming document must contain one or more Descriptive Metadata Section(s) (dmdSec) to describe the top-level metadata for the whole document and the metadata for each related section within that document. For each of dmdSec, it will contain:

a <mdWrap> containing a <xmlData> wrapper around embedded Greenstone metadata. See Greenstone Metadata XML schema above.


There is no amdSec in the current GS METS version yet


The conforming document must contain one file section (<fileSec>) which in turn contains one or more file group(<fileGrp>) element(s) used to indicate and group together related sections.


In addition, a default <fileGrp> is defined which list the original source document and all associated files.


All of the <file> elements have a unique ID attribute which is used to provide a unique, internal name for this file element. This ID can be referenced by other portions of the document (e.g. It will be referenced in the Structural Map Section.)


A METS document conforming to the Greenstone profile contains two Structure Maps (structMap), which are:

1. A <mets:structMap> for each related sections.

2. A <mets:structMap> for the Whole Document.

This is the heart of a METs documents. Each structMap contains an element with a TYPE attribute with value "Section" or "Whole Document".

The Structure Map must contain one high level <div> element with a TYPE attribute with value "Section" or "Document" and a DMDID attribute that references the dmdSec element.

Each <div TYPE=Section> element will contain more divs if there are further sub-sectoions within the document. The <div> will contain one or more File Pointer (<fptr>) elements that reference File(file) element in the File Group(<fileGrp>) section.


There is no <structLink> in the current GS METS version.


There is no <behaviorSec> in the current GS METS version.
