The Arnamagnæan Collection in Copenhagen houses approximately 500 medieval charters from the archive of the Convent of St. Clare (founded 1256) in Roskilde, Denmark. The ongoing project, “Text and Script in Time and Space,” funded by the VELUX Foundation, investigates these final remnants from this now defunct convent from historical, codicological, archival, linguistic and palaeographic angles. At the end of the project, all the findings will be presented and made freely accessible on the project website, diplom.ku.dk. These charters have never been fully catalogued, transcribed, edited or otherwise published, in print or digital form. The project website is thus intended as an interactive catalogue and edition of this collection of documents.

The paper discusses the role of cataloguing in such a project as the “Text and Script in Time and Space,” in which the online interface for documentation of artefacts is designed from scratch. It focuses on the interplay between the catalogue and the edition(s) on the website, which will contain encoded metainformation such as date and place of issue, persons and places (geotagged), document type, and scribal information, as well as a complete multi-level transcription together with photographs of the documents. The paper also addresses challenges of the sustainability of digital data pertaining to medieval manuscripts and possibilities of expanding the project website to include other surviving Danish charters held in the Arnamagnæan Collection.
