XML Perspectives on RDF Querying: Towards integrated Access to Data and Metadata on the Web
نویسندگان
چکیده
The integral processing of data and metadata is starting to get recognized as a central challenge for the next decade (e.g. in Pat Selinger’s ICDE 2005 Keynote) not only as part of realizing the Semantic Web vision, but also on a smaller scale as part of the next generation of desktop data management (cf. Apple’s Spotlight and Microsoft’s WinFS). In this article, we focus on metadata represented in the W3C’s RDF formalism. We illustrate first steps towards integrating access to RDF metadata and access to standard Web data in XML format. For this, two XML views over RDF data are expressed in the query language Xcerpt and discussed. These views illustrate two different approaches for integrating RDF metadata processing and current data processing techniques.

The purpose of this research was to find out the reaction of Web Search Engines to Metadata records created based on the combined method of Rich Snippets and Linked Data. 200 metadata records in two groups (100 records as the control group with the normal structure and, 100 records created based on microdata and implemented in RDF/XML as experimental group) extracted from the information gatewa...
متن کاملQuerying Embedded RDF Data with XML Technology: A Feasibility Study
XML has become the de facto standard for representing and accessing data on the Web. At the same time RDF is becoming more and more popular for representing metadata. While RDF also has an XML-based syntax, storage and query technologies for the two formats are not compatible due to differences in the data model. This is a potential problem when trying to query data that combine XML data with R...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کاملMarriages of Convenience: Triples and Graphs, RDF and XML in Web Querying
Metadata processing is recognized as a central challenge for database research in the next decade. Already, novel desktop data management and search applications (cf. Apple’s Spotlight and Microsoft’s WinFS) are enabled by rich metadata. Efficient and effective access to such data becomes a crucial issue for more and more application scenarios. In this article, we focus on metadata represented ...
متن کاملAn Extensible Framework for Efficient Document Management using RDF and OWL
In this paper, we describe an integrated approach towards dealing with various semantic and structural issues associated with document management. We provide motivations for using XML, RDF and OWL in building a seamless architecture to serve not only as a document exchange service but also to enable higher level services such as annotations, metadata access and querying. The key idea is to mani...
