The next draft of the service description document will likely include a named graph class to go along with the property mentioned above. If the modeling in the example section[1] works for the named graphs you're hoping to describe (the named graph pointed to by the sd:namedGraph property), then the new class will probably be what you're after. Hope that helps. thanks, .greg [1] http://www.w3.org/TR/sparql11-service-description/#id41794
Reminder: Call for Papers - I-SEMANTICS 2010
**Sorry for Cross-Posting** Call for Papers I-Semantics 2010: 6th International Conference on Semantic Systems Graz, Austria, 1 - 3 September 2010 http://www.i-semantics.at including Call for Papers 5th AIS SigPrag International Conference on Pragmatic Web (ICPW 2010) & Call for Submission 3rd Triplification Challenge Scope = I-SEMANTICS 2010 (www.i-semantics.at) is the 6th conference in the I-SEMANTICS series and provides a forum for academic and industrial research & development that focuses on semantic technologies and the Semantic Web. I-SEMANTICS 2010 will bring together both researchers and practitioners in the areas of Linked Data, Social Software and the Semantic Web in order to present and develop innovative ideas that help realising the �Social Semantic Web� and the �Corporate Semantic Web�. I-SEMANTICS 2010 will be the host of this year`s regional Pragmatic Web Conference as well as the third edition of the TRIPLIFICATION Challenge. Further on I-SEMANTICS will be complemented by I-KNOW (www.i-know.at), the 10th International Conference on Knowledge Management. This setup is aiming to reflect the increasing importance and convergence of knowledge management and semantic systems. Topics == The special focus of I-SEMANTICS 2010 is �Towards a Web of Linked Data�. As a conference aiming to bring together science and industry, I-SEMANTICS encourages both, scientific (research/application) and industrial contributions. The following table summarises the topics we are interested in: Web of Data and Linked Data --- � Triplification of existing data � Vocabularies, taxonomies and schemas for use on the Web of Data � Querying, searching and browsing over Linked Data � Coreference detection and dataset reconciliation � Information provenance and quality assessment on the Web of Data � User interaction and visualisation � Applications utilizing open data sets � Linked Enterprise Data, Linked Government Data Corporate Semantic Web -- � Corporate thesauri, corporate business vocabularies / ontologies and business rules � Semantic Business Information Systems � Semantic Business Process Management � Semantic Decision Management � Semantics, Pragmatics and Semiotics in Organizations � Economic and entrepreneurial aspects and business models of Semantic Enterprises Semantic Social Software � Semantic blogging, wikis and content management systems � Semantic Desktop � Semantic mashups � Semantic/structured tagging � Social semantic web and mobile services Semantic Content Engineering � Ontology Engineering & Ontology Merging � Ontology Design Patterns � Ontology Life Cycle Management � Ontology Learning � Linguistic and statistic approaches (text-mining, NLP, etc.) for structuring and extracting content and entities � Automated annotation, extreme tagging and digital curation approaches Building Blocks for Semantic Web Applications - � Scalable inference, retrieval, and persistence of semantic data � Design processes from requirements to maintenance � Design patterns, Best practices and Reference Models � User-interface components, template languages � Integration of distributed repositories � Policy Awareness & Policy Aware Web � Semantic web services Studies, Metrics & Benchmarks - � Case studies of and benchmarks in semantic systems usage � Evaluation perspectives, methods and Semantic Web research methodologies � Technology assessment, acceptance/media choice theories � Usability and user interaction with semantic technologies � Quality analysis of socially generated semantic content � Trust and privacy issues in semantic applications � Economic effects generated by large scale semmantic systems Pragmatic Web Track === The Conference on PRAGMATIC WEB is centered around the study of �pragmatics� in the Semantic Web. That is, it draws attention to how communicative actions with a pragmatic context are performed via Web media and illuminates ho w mutual understanding and commitments to actions can evolve in conversations. For further information about the Pragmatic Web see http://www.pragmaticweb.info/ Topics of Interest -- � Pragmatic Web Science � Theories, Frameworks, Models and Methods �inspired by Pragmatics and Pragmatism, or less formally, case study reflections on �pragmatic� uses of the Web that supported the negotiation of social/work relationships and common ground � Applied pragmatic theory � Communication, dialogue and argumentation models � Pragmatic Web media for communicative actions � Pragmatic collaboration and coordination tools � Pragmatic context models (e.g. within conversation-based collaborations) � Pragmatic design principles for Web contents where tru

Re: What is the class of a Named Graph?
What you pointed at is a property sd:namedGraph. The upcoming SPARQL standard doesn't define any class for named graphs. I support using: http://www.w3.org/2004/03/trix/rdfg-1/Graph Best, Jiri On 02/21/2010 10:40 AM, Michael Hausenblas wrote: > > Nathan, > >> Any further input before I start using rdfg-1:Graph when describing graphs? > > I'd suggest you forget about both references and go with the upcoming > SPARQL standard [1]. > > Cheers, > Michael > > [1] > http://www.w3.org/TR/2010/WD-sparql11-service-description-20100126/#id41744 > signature.asc Description: OpenPGP digital signature
