Multi-level Metadata Integration System: XML, RDF and RuleML
نویسنده
چکیده
Our work is part of the heterogeneous data integration, with the definition of a structural and semantic mediation model. Our aim is to propose architecture for the heterogeneous sources metadata mediation, represented by XML, RDF and RuleML models, providing to the user the metadata transparency. This, by including data structures, of natures fundamentally different, and allowing the decomposition of a query involving multiple sources, to queries specific to these sources, then recompose the result. Keywords—Mediator, Metadata, Query, RDF, RuleML, XML, Xquery.

DR-DEVICE: A Defeasible Logic RDF Rule Language
Defeasible reasoning is a rule-based approach for efficient reasoning with incomplete and inconsistent information. Such reasoning is, among others, useful for ontology integration, where conflicting information arises naturally; and for the modeling of business rules and policies, where rules with exceptions are often used. In this demonstration we present a prototype system for defeasible rea...
متن کاملObject-Oriented RuleML: User-Level Roles, URI-Grounded Clauses, and Order-Sorted Terms
This paper describes an Object-Oriented extension to RuleML as a modular combination of three sublanguages. (1) User-level roles provide frame-like slot representations as unordered argument collections in atoms and complex terms. (2) URI-grounded clauses allow for ‘webizing’ using URIs as object identifiers for facts and rules. (3) Ordersorted terms permit typed variables via Web links into ta...
متن کاملDesigning, Specifying and Querying Metadata for Virtual Data Integration Systems
We show how to specify and use the metadata for a virtual and relational data integration system under the local-as-view (LAV) approach. We use XML and RuleML for representing metadata, like the global and local schemas, the mappings between the former and the latter, and global integrity constraints. XQuery is used to retrieve relevant information for query planning. The system uses an extende...
متن کاملIntegrating XQuery-enabled SCORM XML Metadata Repositories into an RDF-based E-Learning P2P Network
Edutella is an RDF-based E-Learning P2P network that is aimed to accommodate heterogeneous learning resource metadata repositories in a P2P manner and further facilitate the exchange of metadata between these repositories based on RDF. Whereas Edutella provides RDF metadata repositories with a quite natural integration approach, XML metadata repositories have to overcome considerable incompatib...
متن کاملA RuleML-Based Ontology for Interoperation between Learning Objects and Learners
This paper presents a context mediation based approach for achieving interoperability among semantically heterogeneous learning objects and learners. The presented work is focused on building a common ontology for the domain of learning objects participating in data exchange. An ontological graph is proposed as a knowledge representation of the ontology, and methods for manipulating ontologies ...
