EVT was born in the context of the Digital Vercelli Book project, which has been available in beta form for more than one year, but it has evolved in a tool suitable to fit different texts and needs. For example, it is now being used to publish the digital edition of the Codice Pelavicino manuscript, a medieval codex preserving charters dating back to the XIII century. The continuous development and need to adapt it to different types of documents and TEI-encoded texts has shifted the development focus towards creation of a more general tool for the web publication of TEI-based documents, able to cater for multiple use cases.
Critical edition support. Enlarged critical apparatus, variant heat map, witnesses collation and variant filtering are some of the main features developed for the critical edition support.
Bookmark. Direct reference to the current view of the web application, considering view mode, current document, page and edition level, eventual collated witnesses and selected apparatus entry.
High level of customization. The editor can customize both the user interface layout and the appearance of the graphical components.
Currently, the development team is mainly focused on EVT 2. One of our most important goals is to reach feature parity with EVT 1, until this is achieved the former version will continue to be developed and improved.
We also plan to enhance it with additional features: traditional critical apparatus layers, image-text linking leading to selected witness variants, very high resolution image viewer, GIS-like support to show named entities in a map, and more.
EVT is distributed as open source software, all the current code base is available on GitHub.
