3.1 The manuscript viewer: work with EVT
The manuscript viewer is freely accessible, equipped with quality images and features facilitating the consultation and the study of the manuscript.
The viewer is based on the EVT technology. EVT is an open source software and the experiences made with EVT for the Tarsian edition were very positive.1 The tool EVT is designed to create a manuscript viewer with a user-friendly interface from XML TEI-encoded texts.2
Given that we planned a diplomatic edition, we started with EVT 1 and not EVT 2, which is made to display critical editions (EVT 2 supports now diplomatic editions very well too). We started with the version EVT 1.1.1. In March 2017, we updated for EVT 1.2 (see our blog article about this). Minor adjustments were made, for the display of Arabic notably.
Two complementary stages, transcription and encoding, are needed for the integration of folios into the manuscript player. The text is transcribed and afterwards encoded according to the XML TEI standards. The use of XML TEI makes the text readable by the software EVT but above all, it allows adding precious additional information to the transcription. We can mention physical aspects, such as line breaks or color of the text, but also other metadata like the separation into modern verses or informative notes (see the lists of features below).
Moreover, the encoding also helps clarifying to clarify the choices made during the transcription: The transcription follows accurately the manuscript but we add information in order to normalize and standardize the text. For example, if we read in the Greek column the noun David abbreviated as δ͠αδ, we notify that the expanded noun is δαυὶδ. This is encoded that way:
The use of the tag <choice> automatically creates to levels of edition:
- the “diplomatic” version corresponds to a transcription of the text that follows the spelling and other characteristics of the manuscript as closely as possible (<orig>).
- the “normalized” version corresponds to a text that has been normalized and standardized for the reader (<reg>). For the Greek, we write out the nomina sacra and we propose an alternative when there are important errors in the accentuation (mostly breathings). For the Arabic, we add diacritical points when they were missing or misplaced.
In the interface of the manuscript viewer, the user can choose between both levels:
Furthermore, in both cases the alternative is displayed when the user run the mouse over the word:
Each column is treated independently in the current of our viewer. In this way, it is possible to display one language next to the images or two languages next to each other but not more. Since the release of EVT 1.2, it would have been possible to use column breaks:
However, readability is our outmost priority. In our case, we would have to use very small fonts in order to avoid unwanted line breaks. For the time being, the option of toggling among languages seems better suited to our needs, but we are actively working on this question.
List of features
We can outline the following features for the time being:
- The user-friendly interface displaying the desired column next to the related folio or to display two columns next to each other (see also How to use the manuscript viewer).
- Two levels of edition: diplomatic and normalized (forthcoming for Latin).
- The Image-text link option that allows to simplify the reading or the checking in the manuscript.
- An "Hotspot" function that displays alternative images, e.g. details, accompanied by a note.
- Numerous informative notes about the text in the textbody.
We are constantly working to improve the viewer. The next development will be the implementation of an annotation tool.
