The use of metadata expands on the opportunities for interoperability. By interoperability, it is meant the ability to develop conventions that enable data exchange and integration. Metadata descriptions from different domains are not semantically distinct but overlap and relate to each other in complex ways. As the number, size and complexity of the(More)
Semantic Web applications that include map visualization clients are becoming common. When the description of an entity contains coordinate pairs, semantic applications often lay them as pins on maps provided by Web mapping service applications, such as Google Maps. Nowadays, semantic applications cannot guarantee that those maps provide spatial information(More)
This work proposes an architectural style, a pattern, for SDIs. This style provides a tool and a shared vocabulary to help system architects to design these infrastructures, and facilitates the exchange of knowledge about them. This style is defined under the component-andconnector architectural viewtype, extending the client-server and shared-data styles.(More)
The use of open technologies and standards have made easier the integration of Web services into end-applications. These interoperable services have been organized on distributed architectures over Internet in accordance with shared functional principles. But these Web-service architectures have not resolved the distributed computing difficulty in ”gluing(More)
The tendency of current cataloguing systems is to interchange metadata in XML according to the specific standard required by each user on demand. Furthermore, metadata schemas from different domains are not usually semantically distinct but overlap and relate to each other in complex ways. As a consequence, the semantic interoperability has to deal with the(More)
Ontologies are used within the context of Spatial Data Infrastructures to denote a formally represented knowledge that is used to improve data sharing and information retrieval. Given the increasing relevance of semantic interoperability in this context, this work presents the specification and development of a Web Ontology Service (WOS), based on the OGC(More)
One of the essential components for the construction of a geographic spatial data infrastructure at a regional, national or global level is the geographic information catalog server. But, for the catalog to be a useful component, it must enable access to geographic information metadata independently of the nature of search client applications, in other(More)
