Integration of Spatial XML Documents with RDF
نویسندگان
چکیده
The fact that GML is an XML encoding allows it to be queried. In order to query a GML document we have designed a query language over GML/XML enriched with spatial operators. This query language has an underlying data model and algebra that supplies the semantics of the query language. In this paper, we propose an approach for integrating Geospatial data on the Web, stored in GML documents, using our Spatial Query language. This approach has been inspired by Web Portals technology for retrieving Geospatial information. We have used ontologies to solve the semantic heterogeneity between different GML documents.

Specifying multimedia access control using RDF
The Synchronized Multimedia Integration Language (SMIL) [Aya01] is an W3C [W3C03] specification for authoring multimedia documents. Although SMIL has XML like syntactic constructs, unlike XML, SMIL compositions have an intended semantics stemming from intuitive notions of playing out many media streams relative to each other. Although there are many excellent models for XML access control [DdVP...
متن کاملRDF Databases for Querying XML. A Model-mapping Approach
Some recent research works face the challenge to map XML documents to RDF triples. Ontologies are used to establish semantic connections among XML applications, and some mechanisms have been defined to query them with natural XML query languages like XPath and XML Query. Generally structure-mapping approaches define a simple translation between trivial XPath expressions and a target RDF query l...
متن کاملContorsion: A Semantic XPath Processor
This work describes the architecture of Contorsion, a semantic XPath processor that acts over an RDF mapping of XML. It contributes to a recent research trend that defines an XML-to-RDF mapping allowing XML documents interoperate at the semantic level. We use a model-mapping approach to represent instances of XML and XML Schema in RDF. This representation retains the node order, in contrast wit...
متن کاملXSDL: Making XML Semantics Explicit
The problem that “XML formally governs syntax only not semantics” has been a serious barrier for XML-based data integration and the extension of current Web to Semantic Web. To address this problem, we propose the XML Semantics Definition Language(XSDL) to express XML author’s intended meaning and propose a model-theoretic semantics for XML. Consequently, XML becomes a sub-language of RDF in ex...

The emerging Semantic Web may change business integration from using partial, ad-hoc and costly connections to a qualitatively new level providing universal representation and transformation means for business terminologies, documents, business processes, services, and business models. Currently, the Semantic Web is based on representation languages like XML, RDF (Schema), and OIL, however it l...
