Semantic copyright management for internet-wide knowledge sharing and reuse

an article by Roberto García González and Rosa Gil in Online Information Review Volume 32 Issue 5

Abstract
Purpose
To extract the full potential from Internet-wide knowledge sharing and reuse, the underlying copyright issues must be taken into account and managed using digital rights management (DRM) tools. The paper aims to focus on the issues involved.
Design/methodology/approach
Traditional DRM and open licensing initiatives lack the required computerised support and flexibility to scale to Internet-wide copyright management. The authors approach is based on a semantic Web ontology that conceptualises the copyright domain.
Findings
The Copyright Ontology facilitates interoperation while providing a rich framework that accommodates copyright law and copes with custom licensing schemes.
Research limitations/implications
The ontology is based on the description logic variant of the Web Ontology Language. Despite its scalability, this variant has some limitations on expression that will be overcome with the help of semantic web rules in future versions of the ontology.
Practical implications
The ontology provides the building blocks for flexible machine-understandable licenses and facilitates implementation because existing semantic web tools can be easily reused. Moreover, existing initiatives can be mapped to the ontology to make it an interoperability hub.
Originality/value
The paper contributes a novel approach to DRM, based on semantic web technologies, that takes into account the underlying copyright legal framework. This is possible thanks to the greater expressiveness of semantic web knowledge representation tools.
