Digital Edition Publishing Cooperative for Historical Accounts


The Project DEPCHA, an Andrew W. Mellon funded cooperation of five US partners and the Centre for Information Modelling at Graz University, aims to link the knowledge domain of economic activities to historical accounting records. For this purpose the so-called Bookkeeping-Ontology is developed.DEPCHA creates a publication hub for digital editions, converting multiple formats into RDF and allows the usage of various retrieval and visualization functionalities, as well as interoperability and reuse of information in the sense of Linked Open Data.
