Editorial Data Interfaces and Visualization Tools

This task provided the main functionality for publishing, searching, browsing and exploring interlinked legal information. This included querying and facet-based browsing of dataset metadata along various dimensions (dataset type, spatial/temporal coverage, origin etc.), as well as authoring of new metadata and data. It also investigated issues, such as access control and user rights management, to enable customized access levels for various user roles and clients. Additionally, different visualizations of e.g. geo location and statistical information were implemented (see LOD2 work package 5, Chap. 5).

Business Impact and Relevant Pre-conditions for Success

This task investigated into Intellectual Property Rights (IPR) management (licensing and management of usage rights) as well as business value of interoperable metadata. While traditional regimes, especially in the private sector, mostly rely on a Strong-IPR philosophy, by which the use and commercial exploitation of metadata is strictly regulated and governed, interoperable metadata requires more flexible licensing arrangements that take advantage of opennessand commons-based approaches. While the continuum between and the interplay of strong and light intellectual property rights for interoperable metadata is still a young and unexplored research field, it is the licensing strategy that defines the legal framework in which asset diversification and value creation takes place. The application of the uniform data model of RDF to metadata enables syntactic and semantic interoperability and leverages the network characteristics of metadata. While the lack of a uniform data model leads to proprietary lock-ins with respect to metadata assets like schemata, vocabularies, ontologies, indices, queries etc., interoperable metadata transcend these boundaries and open up possibilities for asset creation under the circumstances of economies of scale and positive feedback (Metcalfe's Law) as well as the social dynamics behind it (Reed's Law). Diversification for interoperable metadata can be looked at from a resource-based and a market-based point of view. The resource-based approach investigates how economically valuable resources are created and commercially exploited. The market-based approach looks at new customers and market segments that can be entered and secured.
