The TEI P4 DTD files

From this page you can download current versions for all the files which make up the current version of the TEI DTD. For information about how these DTD fragments should be used and how these files interact, you need to read the Guidelines themselves. For a brief overview of the files in the DTD, please see Chapter 36 of the TEI Guidelines, from which the table below is reproduced.

The TEI DTD files can be customized in many different ways, to make large or small DTDs according to need. TEI Lite is one such customization of the whole; its DTD files are at www.tei-c.org/Lite/DTD; Master is another such customization, and there are many others. Full reference information on how to perform such customization (using TEI Lite as an example) is provided in Chapter 29 of the Guidelines.

Experimental work is currently underway to investigate the automatic production of Relax NG schemas for use with the TEI Guidelines.

Moving from P3 to P4

If you are still using the P3 DTDs and wish to upgrade you can choose to either use P4 as SGML or P4 as XML. The TEI strongly recommends the latter, and the NEH-funded TEI Migration Task Force has written extensive reports on the process of migrating from P3 to P4 XML. They can be found on what is affectionately called the migration page.

If you wish to try the P4 DTDs in your current SGML environment, you can do so by either of the following methods: replace the system identifiers in your local files by a link to the new version at (mutatis mutandis) http://www.tei-c.org/Guidelines/DTD/tei2.dtd (see examples below); download and install all the new dtd files locally, changing the system identifiers to point to these local versions. The complete suite is available as a single archive file.

Neither the actual filenames (teicore2.dtd etc.) used nor the method of constructing application specific DTDs has changed with this release. For example, if you currently test files using a driver that begins <!DOCTYPE TEI.2 SYSTEM "/home/wherever/mylocalteistuff/tei2.dtd" [ <!ENTITY % TEI.prose "INCLUDE" > ... ]><TEI.2> ... and you have not yet changed the contents of home/wherever/mylocalteistuff, then you could experiment with the new DTDs simply by changing your driver file to reference the online version. The file would then begin: <!DOCTYPE TEI.2 SYSTEM "http://www.tei-c.org/Guidelines/DTD/tei2.dtd" [ <!ENTITY % TEI.prose "INCLUDE" > ]> ...

The TEI editors are particularly anxious to receive reports of errors with documents that were regarded as valid by previous releases of the TEI DTDs, but which the new DTDs will not accept. Send feedback of any kind to editors@tei-c.org, or, if you want to discuss issues raised more widely with other TEI users, to tei-tech@listserv.brown.edu. Thank you!

The TEI DTD files

The following tables give for each of the files making up the current release: the filename used in the release directory; the type of declarations contained in the module; the full name of the module, for use in constructing its Formal Public Identifer (FPI) a link to the chapter or section in which it is defined . To make up the Formal Public Identifier, the full name of the module should be prefixed by the string `-//TEI P4//` and the type of declarations contained, and suffixed by the string `//EN`. Thus the FPI for the first file listed below should be `-//TEI P4//ELEMENTS Additional Element Set for Simple Analysis//EN`. Each table corresponds with a single TEI module or tag set i.e. a group of related DTD fragments. Tables are listed in alphabetical order.
