Textus: an open source platform for working with collections of texts and metadata by Jonathan Gray.
A proposal, based on WordPress as the main CMS, to work with digital texts.
Not to be critical, as all efforts have to start somewhere, but the TEI – Text Encoding Initiative in 1987, was a late-comer to the digital text party, which had started in the late 1950’s or early 1960’s. Efforts starting now, are even later late-comers to the digital text party. And there were efforts before and after the TEI project.
To be quite honest, I don’t know of any complete survey of all the digital text projects and/or repositories. Much less an inventory of the methods, encodings and texts that were the objects of such projects.
The use of topic maps in such a project would make the integration of prior and following efforts with digital texts much easier.
