SPASE "allowed values" ontology - Semantic Web based glue for the connection of EU-ESPAS and Japanese IUGONET projects
Abstract
Both the European Union project ESPAS (2011-2015) and the Japanese IUGONET project (2009-2014) have the same scientific objects: the design, implementation, and provision of an e-science infrastructure for the retrieval and access to space weather relevant data, information and value added services. Despite similarity of the data model, basic system ideas, and techniques the physical implementation of the system backend and web portal are different. The IUGONET system, which is already operating since 2011, is based on DSPACE's metadata registering, retrieving, providing and harvesting capabilities, whereas the ESPAS system software (still in development) is based on OGC compatible standards and components. IUGONET uses an extension of the SPASE data model, both for the structure and for the values of metadata. ESPAS plans to use an enhanced version of the SPASE based context related values. This means, from a semantic point of view, the used keyword vocabulary for the description of context information of information objects, such as e.g. data files, is almost the same in both projects. Modeling the controlled SPASE keyword vocabulary ("allowed values") in the SPASE standard as SKOS based ontology enables the use and reuse of a common and standardized keyword vocabulary in the space weather domain. This vocabulary can be reused in related projects like the GFZ ISDC ontology network that uses a semantic web based approach and related implications such as linked data integration and inference based reasoning. This paper describes a first modeling approach of the SPASE keyword ontology based on SPASE version 2.2.2 and the connection with other keyword vocabularies. Another aspect is the demonstration of the integration of the SPASE keyword ontology into the SPACE software and the description of the planned integration into the ESPAS software.
