Remarks

In order to encourage uniformity in the provision of metadata across document types, this element is modelled on an element in the Text Encoding Initiative (TEI) standard. This information is often essential in a machine-readable environment. Five sub-elements must be encoded in the following order: altId(optional), fileDesc(required), encodingDesc(optional), workList(optional), and revisionDesc(optional). These elements and their sub-elements provide: a unique identifier for the MEI file, bibliographic information about the MEI file and its sources, information about the encoding process, information about the creation of the work being encoded, and statements regarding significant revisions of the file. The xml:lang attribute may be used to indicate the language in which the metadata content of the header is provided.
