Semantic Provenance Registration and Discovery using Geospatial Catalogue Service
نویسندگان
چکیده
A geospatial catalogue service allows geospatial users to discover appropriate geospatial data and services in a Web-based distributed environment. Metadata for geospatial data and services is organized structurally in catalogue services. Provenance for geospatial data products, as a kind of metadata describing the derivation history of data products, can be managed in a same way as other kinds of metadata using metadata catalogue services, thus keeping consistency and interoperability with existing metadata catalogue services. Meanwhile, Semantic Web technologies have shown considerable promises for more effective connection, discovery, and integration of provenance information. This paper addresses how geospatial catalogue services can be enriched with semantic provenance. Semantic relationships defined in provenance ontologies are registered in an OGC standard-compliant CSW service by extending ebRIM elements. The work illustrates that such a semantically-enriched CSW can assist in the discovery of data, service, and knowledge level of geospatial provenance.

Restful Implementation of Catalogue Service for Geospatial Data Provenance
Provenance, also known as lineage, is important in understanding the derivation history of data products. Geospatial data provenance helps data consumers to evaluate the quality and reliability of geospatial data. In a service-oriented environment, where data are often consumed or produced by distributed services, provenance could be managed by following the same service-oriented paradigm. The ...
متن کاملIntegrating semantic web technologies and geospatial catalog services for geospatial information discovery and processing in cyberinfrastructure
A geospatial catalogue service provides a network-based meta-information repository and interface for advertising and discovering shared geospatial data and services. Descriptive information (i.e., metadata) for geospatial data and services is structured and organized in catalogue services. The approaches currently available for searching and using that information are often inadequate. Semanti...
متن کاملSharing geospatial provenance in a service-oriented environment
One of the earliest investigations of provenance was inspired by applications in GIS in the early 1990’s. Provenance records the processing history of a data product. It provides an information context to help users determine the reliability of data products. Conventional provenance applications in GIS focus on provenance capture, representation, and usage in a stand-alone environment such as a...
متن کاملAugmenting geospatial data provenance through metadata tracking in geospatial service chaining
In a service-oriented environment, heterogeneous data from distributed data archiving centers and various geo-processing services are chained together dynamically to generate on-demand data products. Creating an executable service chain requires detailed specification of metadata for data sets and service instances. Using metadata tracking, semantics-enabled metadata are generated and propagate...
