Introduction

Modern digital library systems not only store bibliographic metadata but also an electronic representation of the content itself. Depending on its type, content typically follows some structure, e.g. we can decompose a book into chapters and provide individual descriptions for each chapter with information about re- lations between them. Including structural concepts in ontologies and using these concepts in metadata descriptions provides a universal layer for metadata and content retrieval. It allows to extend the structure description with new concepts, without violating the integrity of existing data. The application of ontologies for structural descriptions enables uniform access to structural and bibliographical information, and delivers new search and discovery possibilities, as described in Kruk et al.

JeromeDL Ontology Overview

Standards

It is important to understand that the JeromeDL ontology as specified in this document is not a standard in the sense of ISO Standardisation, or that associated with W3C Process.

JeromeDL ontology depends heavily on W3C's standards work, specifically on XML, XML Namespaces, RDF, and OWL.

This specification contributes an ontology, "JeromeDL structure ontology", to the Semantic Web, specifying it using W3C's Resource Description Framework (RDF). As such, JeromeDL adopts by reference both a syntax (using XML), a data model (RDF graphs) and a mathematically grounded definition for the rules that underpin the RDF design.
