Abstract

The concept of an application profile (AP) has been developed to allow implementers to draw on metadata terms from existing vocabularies and customise them for a local application. APs play an important role in enhancing interoperability between diverse applications. From our experience of encoding an AP targeted to the digital heritage domain, we have devised a generalized XML Schemas Definition (XSD) framework capable of satisfying the functional and modelling characteristics of APs with either flat or nested structures. This paper presents the framework and its technical implementation, its potential impact on the development of dynamic machine- processible APs, and its current limitations. The framework presented has a layered structure to explicitly separate the authoritative, the non-authoritative, and the application profile schemas. We believe this framework to be an important step in encoding APs that can be dynamically updated with information relating to the terms they reuse, directly from schemas on remote locations (e.g. the web), enabling the automatic creation and validation of AP instance records.

Item Type: Article
Additional Information: Originality: An innovative XML Schema capable of satisfying functional and modelling characteristics of Application Profiles (AP). It provides a more efficient machine-processible way to dynamically create an AP based implementation of the AMS. Rigour: Two case studies implement the AMS and the Internet Public Library-Asia (IPL-ASIA) as APs demonstrating an XML only schema without recourse to other schemas such as RDF. Significance: Metadata designers can use existing vocabularies, customising them for local applications, making metadata element sets simpler, and more efficient. Impact: This research, now publicly available, forms part of a new research area in digital heritage systems funded by the European commission in FP5.
