Maintaining instance-based constraints in the Metadata View Graph [chapter]

Jeff Pittges
1997 IFIP Advances in Information and Communication Technology  
This paper reviews existing methods for constraint discovery, describes how constraints are stored in the Metadata View Graph at compile-time, and describes how the MVG Framework retrieves and maintains  ...  A Metadata View Graph (MVG) is a metadatabase that stores instance-based constraints, along with statistical and structural metadata, for logical views of the database.  ...  The author has been generously supported by BNR Inc., the research and development subsidiary of Northern Telecom, and is especially grateful to Robert Bloedon and Deborah Stokes.  ...

Sugumaran Nallusamy
2011 International Journal of Information and Electronics Engineering  
The framework generates the ontology to enhance the program understanding in semantic levels by defining knowledge which is relevant to the domain of interest.  ...  The redocumentation process is done semi automatically which was initiated by the Software Work Products (SWP) and maps out to the metadata and generates it as ontology.  ...  specification, data flow graph for specific use case, relationship among components using the semantic relationship from the domain point of view.  ...

Grid metadata management: Requirements and architecture

Oscar Corcho, Pinar Alper, Paolo Missier, Sean Bechhofer, Carole Goble
2007 2007 8th IEEE/ACM International Conference on Grid Computing

Intellectual Property Rights Management Using a Semantic Web Information System [chapter]

Roberto García, Rosa Gil, Jaime Delgado
2004 Lecture Notes in Computer Science  
Metadata is associated to IPs (Intellectual Properties) using URIs and it is structured using web ontologies. There are descriptive, rights and e-commerce ontologies for the different views on IPs.  ...  This requirement and the objective of easy Web integration have made the Semantic Web technologies the best choice. NewMARS is a semantics enabled metadata managing system.  ...  The final part of the work presented was developed within VISNET, a European Network of Excellence (http://www.visnet-noe.org), funded under the European Commission IST FP6 program.  ...

A survey of techniques for achieving metadata interoperability

Bernhard Haslhofer, Wolfgang Klas
2010 ACM Computing Surveys  
Currently there exist many interoperability techniques, with quite varying potential of resolving the structural and semantic heterogeneities that can exist between metadata stored in distinct repositories  ...  Based on our work, domain experts and technicians get an overview and categorization of existing metadata interoperability techniques and can select the appropriate approach for their specific metadata  ...  ACKNOWLEDGMENTS The authors would like to thank Wolfgang Jochum and Bernhard Schandl as well as our referees for their valuable comments on this paper.  ...

Web metadata: a matter of semantics

O. Lassila
1998 IEEE Internet Computing  
The Resource Description Framework, with its focus on machine-understandable semantics, has the potential for saving time and yielding more accurate search results.  ...  The sheer volume of information can make searching the Web frustrating.  ...  ACKNOWLEDGMENTS The author would like to thank R.V. Guha  ...

Personalised Grid service discovery

S. Miles, J. Papay, V. Dialani, M. Luck, K. Decker, T. Payne, L. Moreau
2003 IEE Proceedings - Software  
We also discuss the use of a rich, graph-based rdf query language for syntactic queries on this data. Finally, we analyse the performance of each of these contributions in our implementation.  ...  We take a broad view that ultimately Grid-or Web-services must be located via personalised, semantic-rich discovery processes.  ...  RDF and RDQL rdf, the W3C Resource Description Framework [11] was originally developed as a framework for describing and interchanging metadata for published data on the Web.  ...

Libraries, languages of description, and linked data: a Dublin Core perspective

based on a "statement" model, and how new approaches to metadata evolved to bridge the gap between these models.  ...  Design/methodology/approach -The article focuses on how the Dublin Core -originally seen, in traditional terms, as a simple record format -came increasingly to be seen as an RDF vocabulary for use in metadata  ...  The WEMI sub-graphs hold four sets of statements reflecting four complementary views of a resource (see the appended diagrams in Murray and Tillett, 2011b) .  ...

SKOS and the Semantic Web: Knowledge Organization, Metadata, and Interoperability

Eric Robinson
2010 SOAR@USA: Scholarship and Open Access Repository  
The Simplified Knowledge Organization System (SKOS) is a Semantic Web framework, based on the Resource Description Framework (RDF) for thesauri, classification schemes, and simple ontologies.  ...  It allows for machine-actionable description of the structure of these knowledge organization systems (KOS) and provides an excellent tool for addressing interoperability and vocabulary control problems  ...  The ontological relations of the thesaurus, being hierarchical in nature can be viewed as a branching tree structure with each concept class being treated as a node in the structure.  ...

A Framework for Filtering and Packaging Hypermedia Documents [chapter]

Lucimar C. Martins, Tatiana A. S. Coelho, Simone D. J. Barbosa, Marco A. Casanova, Carlos J. P. de Lucena
2002 Lecture Notes in Computer Science  
The framework dissociates the packaging process from the filtering and formatting processes, and thus facilitates the implementation, user testing and finetuning of the system representations and algorithms  ...  Despite great effort in attempting to develop systems that personalize both content and presentation, there are still some important challenges related to information filtering, packaging and formatting  ...  Tatiana Coelho and Simone Ba rbosa thank CNPq for supporting their research.  ...
