It is our great pleasure to announce the official release of the TEI Publisher, an open source app for eXist-db offering single-source publishing without writing any code. Currently TEI Publisher works out of the box with TEI documents (hence its name) but it can be customized to accommodate any XML schema.
Publishing any TEI content requires only few simple steps:
- Upload the content into eXist
- Customize the appearance via TEI ODD file
- Generate a robust standalone application
Apps generated with TEI Publisher work well across devices and include features like page by page browsing, search and cross-media export or side-by-side text and image display. This approach has been applied to a range of commercial and academic projects, and has proven very successful in terms of development time, maintenance cost, performance and scalability, an outstanding example being the Foreign Relations of the United States series at the US Department of State.
TEI Publisher builds upon an efficient implementation of the TEI Processing Model, which has become a standard part of TEI Consortium’s recommendations, so customising the appearance of the text is done in TEI XML. No media specific stylesheets are required since rendition choices are transparently translated into different media types like HTML, XSL-FO, LaTeX, or ePUB.
TEI Publisher empowers the editors, offering rapid publishing across media while assuring full control over editorial decisions. For developers, TEI Publisher heavily reduces the amount of custom code required by typical digital edition. Transformations can be customized just by tweaking a single processing specification expressed in TEI ODD and changes are consistently carried through into all output formats. Highly formulaic and easily readable TEI ODD processing models save thousands of lines of handwritten transformations. Typically less than a few hundred lines of ODD instructions are sufficient to cover the needs even for projects of broad scope and volume, sustaining substantial everyday traffic. This means roughly ten-fold decrease in code size alone, not mentioning drastic improvements in maintenance.
Having its roots in the TEI community, TEI Publisher is obviously well-suited to publishing TEI documents, but by no means are its applications limited to documents encoded in TEI (or TEI Simple) schema. Thanks to the universality of the Processing Model, the TEI Publisher can be made to work with any XML vocabulary as long as default processing models are defined for it. Moreover the processing model library can be used independently of the TEI Publisher app.
TEI Publisher is a free software released under GPLv3 licence. It requires eXist-db v3.0 and can be installed from the Dashboard via Package Manager.
We welcome and strongly encourage other contributions, both via community engagement and pull requests as well as financial support and other forms of cooperation. Ideas for future developments include:
- preconfigured app templates to cover specific TEI use cases like EpiDoc, epistolary corpora or manuscripts, as well as support for different layouts (e.g. facsimile display). We are looking for your suggestions and contributions in this area,
- more output options: we would welcome some TeX specialists to improve the current LaTeX output mode. There are also concrete plans concerning an interface to indesign,
- a visual ODD editor to facilitate creation of processing model instructions,
- extension for the TEI processing model library to transform other XML languages.
We hope you will find this project interesting and useful and encourage you to visit the project website and try it out together with new eXist-db release.
