Document Type Definition

Version 1.1 (5 May 2004)


Back to list of contents


All XML-encoded documents should refer to a Document Type Definition (DTD) or a schema to ensure consistency in their document structure. We have decided to base our encoding on the XML version of TEI P4. In order to create a single Document Type Definition out of TEI's library of DTD-fragments we have used the PizzaChef program, which is available through the TEI website.

We have made some changes to the original DTD to make it better suited to some special needs in our project. One of the more significant changes is the introduction of the <dipl>, <facs> and <norm> elements, as well as modifications to the elements <w> and <supplied>. We have also included all elements for manuscript description as recommended by the MASTER project (MASTER reference manual).

A complete list of deviations from TEI P4 have been listed here.

Since May 2001, all changes and modifications to the DTD have been written into the two files norron.extensions.ent and norron.extensions.dtd.

After first having defined the two extension files mentioned above, a DTD is created by using the PizzaChef program. This way, our extension files constitute a part of the base from which the final DTD is generated.

All updates and changes to the DTD have to be written into the extension files, and a new DTD will then have to be created by using the PizzaChef. The procedure for how the DTD is revised and updated is outlined in this instruction.
