Automatic Metadata Creation for Supporting Interoperability Levels of Spatial Data Infrastructures
Miguel Ángel Manso Callejo, Mónica Wachowicz, A. Bernabé-Poveda · 2009
Interoperability in Spatial Data Infrastructures (SDI) is a full-grown subject and an objective with many shortcomings as far as definition of standards for geographic data transfer and exchange, different data types ’ integration, and comprehensive semantic models is concerned. There is a vast literature available on interoperability models containing different interoperability levels, including technological, syntactic and semantic levels. However, very limited research has been carried out on the development of interoperability models for the implementation of Spatial Data Infrastructures (SDI). This paper provides a short review of the main advances in interoperability related to SDI. It also discusses the important role of metadata elements in the formalization of interoperability models for the implementation of SDI. We propose an integrated interoperability model based on the definition of a common template that integrates seven interoperability levels: technical, syntactic, semantic, pragmatic, dynamic, conceptual and organizational. The implementation is carried out by automatic production of ISO19115 metadata. Finally, the results outline the strength and deficiencies in terms of the dynamic interoperability level of SDI based on the elements of ISO19115 metadata.
