Applying a Dublin Core application profile to the digital Pina Bausch archive for ontology population management and data presentation purposes

Authors: Kerstin Diwisch / Bernhard Thull (Hochschule Darmstadt, Germany)

Abstract:
In recent years, it has become common practice in Linked Data application development to utilize application profiles for describing and constraining metadata and structure of these applications. Description Set Profiles (DSP), as proposed by the Dublin Core Metadata Initiative (DCMI) as a means of machine readable formalizations of application profiles, take this development into account. However, even with the use of application profiles, Linked Data application developers are still left with challenges concerning data input or presentation of data, especially for large datasets. An example of a large dataset is the digital Pina Bausch archive which is realized as a Linked Data archive containing data on diverse materials such as manuscripts, choreography notes, programmes, photographs, posters, drawings and videos related to Pina Bausch’s work, adding up to about 20 million triples. To address this topic, we developed and implemented a Description Set Profile in RDF containing metadata structure and constraints for the Pina Bausch archive ontology. Initially, the DSP was mostly used as a controller for an interactive form-based data editor. In the course of the project, we enhanced the DSP with information about frontend data presentation in a form that by now, it is not only used for controlling the data input flow but also as part of a controller for our archive browser. In this talk, we will provide an insight into the development of the DSP and discuss the approach.

22. Conclusion and outlook • DCAP with a machine-readable DSP is a viable way for data mapping and data format validation • Needed: Editor for the DSP • View templates? • Waiting for a W3C recommendation Dec-02 22
