The research work consists in proposing an approximation to the digital editing in TEI/XML of a “capbreu” from the XIV century. The proposal, addressed as a case study, falls within the practice of Digital humanities. An exploratory exercise of digital editing based on TEI coding is carried out, presenting the possibilities of analysis, storage, access and exploitation of “capbreus”, as archival documents, as well as identifying the advantages and disadvantages of executing a project of that kind.
