This release (Codename: Tea Day) marks the completion of two major new features introduced in the previous release. First, Pure ODD is now completely pure: all content models in TEI ODDs may now be represented entirely in TEI, with no requirement for RELAX NG (which may still be used if desired). In the previous release, RELAX NG was still needed in macros that permitted any XML content, which are used in content models such as egXML. Second, this release contains the first Exemplar which implements the Processing Model specification introduced in 3.0.0 and produced as part of the work of the TEI Simple project, which was funded by the Andrew W. Mellon Foundation. TEI simplePrint is an entry-level customization, focused primarily on the needs of those encoding Western European early modern printed material such as that produced by the Text Creation Partnership. We hope that, beyond its value as a customization for working with this type of material, it will serve as a template for producing other new customizations that leverage the Processing Model.
Release 3.1.0 of the TEI Guidelines also introduces other new features and resolves a number of issues raised by the TEI community. As always, the majority of these changes and corrections are a consequence of feature requests or bugs reported by the TEI community using the GitHub tracking system. If you find something you think needs to change in the TEI Guidelines, schemas, tools, or website, please submit a feature request or bug issue at https://github.com/TEIC/TEI/issues for consideration. A full list of the issues resolved in the course of this release cycle may be found under the 3.1.0 milestone.
- The source attribute is now global.
- There is a new schemaRef element for pointing to one's TEI ODD customization.
- note and witDetail are now permitted in rdgGrp.
- A new datatype teidata.prefix has been introduced to allow restricting an attribute value to one that could be use as a URI scheme name.
- The ident attribute of prefixDef is now restricted to the new teidata.prefix datatype. This will avoid errors which would occur if a character that is not legal as a URI scheme were used as part of this attribute’s value.
- Further formal constraints on the output and predicate attributes of model have been added to try to help users avoid ambiguous sets of models elements.
- ISO Schematron is now the only flavor of Schematron used or supported by the Guidelines.
- The following constructs are now deprecated:
- the value isoschematron of scheme of constraintSpec (use schematron instead, as they mean the same thing now).
- the default value (false) of defective of att.msExcerpt
- the default value (unknown) of status of availability
- the default value (unknown) of status of correction
- the default value (unknown) of aloud of said
- the default value (unknown) of discrete of sound
- The rules regarding f, its content, and its fVal attribute, have been cleaned up to fix a contradiction.
- The title element is now a member of att.datable.
- The listBibl element is now a member of model.frontPart.
- A new element called anyElement has been introduced, which permits any XML content in a content model. This removes the last remaining requirement for RELAX NG in content models, allowing us to define TEI entirely in TEI.
- A new element called dataFacet for restricting references to W3C datatypes in ODD has been introduced.
- supplied is now part of model.choicePart, so it can be used within choice.
- A new attribute require has been added to att.textCritical. It can be used to indicate interdependance between variant readings.
- The extent attribute on the orth and pron elements no longer has a default value.
- A new Exemplar called simplePrint has been added. Developed as part of the TEI Simple project, it makes extensive use of the processing model techniques introduced in the previous release and is fully documented by the ODD included in this release.
- The TEI conference and members meeting 2016 in Vienna saw the first ‘TEI2German Translatathon’ to translate several descriptions, glosses, and remarks of the TEI specification into German. The results of this community effort have been added to this release – many thanks again to all participants and the local organizers for all the commitment and enthusiasm!
In addition, dozens of wording improvements and corrections of typographic errors have been made to the Guidelines.
Many improvements, including support for the new anyElement and for the minOccurs and maxOccurs attributes used by Pure ODD have been made to the XSL stylesheets (which provide processing of TEI ODD files for Roma and OxGarage as well as other TEI conversions). The Stylesheets are maintained separately from the Guidelines and are at https://github.com/TEIC/Stylesheets.
