XDependency: maintaining relationships between XML data resources
نویسنده
چکیده
This paper proposes an XDependency description model and language that can be used as part of a distributed integrity control system for XML data resources. The dependency description language allows relationships to be specified between XML data available from different organizations. The paper also includes a prototype agent-based system capable of enforcing distributed dependency relationships. An XDependency maintenance system should make it possible to automate the distributed integrity control for XML resources. q 2003 Elsevier B.V. All rights reserved.

Constraint Satisfaction in Semi-structured Data Graphs
XML data can be modeled as node-labeled graphs and XML queries can be expressed by structural relationships between labeled elements. XML query evaluation has been addressed using mainly database, and in some cases graph search, techniques. We propose an alternative method that models and solves such queries as constraint satisfaction problems (CSPs). We describe common constraint types occurri...
متن کاملITW - An Architecture based on Distributed Web Components for Multimedia Resource Discovery
The paper presents a multi-platform and multi-language architecture used to discover (multimedia) resources. This platform, called ITW, is based on different distributed Web components, such as Web services and Web agents, exploiting the relations between Web sites’ resources. All involved information within the system is XML-based, by using different languages for expressing associated metadat...
متن کاملOn the Maintenance of Materialized XML Views
Providing services by integrating information available in web resources is one of the main goals of a mediation architecture. In this paper, we consider the standard wrapper-mediator architecture under the following hypothesis: (i) the information exchanged between wrappers and the mediator consists in XML documents, (ii) wrappers have limited resources, and (iii) to answer queries even if sou...
متن کاملLinking to Linguistic Data Categories in ISOcat
ISO Technical Committee 37, Terminology and other language and content resources, established an ISO 12620:2009 based Data Category Registry (DCR), called ISOcat (see http://www.isocat.org), to foster semantic interoperability of linguistic resources. However, this goal can only be met if the data categories are reused by a wide variety of linguistic resource types. A resource indicates its usa...
متن کاملModeling and querying of distributed XML data in presence of 3rd party links
XML (short for eXtensible Markup Language) is a meta-language for the representation of digital data. XML has had an enormous impact on modern computer science and IT industry since its advent in 1997, for several reasons: XML is simple and easily accessible. Using Unicode as encoding, XML can be viewed and authored/edited with common text editors, and due to the context-free and well-formed st...
