Features and Requirements for an XML View Definition Language: Lessons from XML Information Mediation
نویسندگان
چکیده
In such an environment a query language will serve for more than "a souped-up version of X-Pointer". Our position focuses on the use of an XML query language as a view definition language that drives XML mediator systems. A mediator selects, restructures and merges information from multiple autonomous sources/sites. It exports an integrated XML view document. Possible applications of such mediator systems are numerous (e.g., virtual shopping malls, virtual agencies, ...).

An Extensible Model-Based Mediatior System with Domain Maps
Mediator systems federate and integrate data from disparate sources in order to elicit information that the individual sources cannot provide independently. The standard mediator architecture employs wrappers that translate heterogenous source data into a common (often semistructured) data model like XML. A “mediation engineer” provides an integrated view definition (IVD) on the wrapped XML sou...

Due to the increasing number of documents, XML, effectively organize these documents in order to retrieve useful information from them is essential. A possible solution is performed on the clustering of XML documents in order to discover knowledge. Clustering XML documents is a key issue of how to measure the similarity between XML documents. Conventional clustering of text documents using a do...

The majority of Information Systems is concerned by heterogeneity in both data and solutions. The use of this data thus becomes complex, inefficient and expensive in business applications. The issues of data integration, data storage, design and exchange of models are strongly linked. The need to federate data sources and to use standard modelling formalism is apparent. In this paper, we propos...
