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.

Reminder: Call for Papers - I-SEMANTICS 2010

2010-02-21 Thread Tassilo Pellegrini
**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

Well spotted! But I didn't really say: here is the class name. I wanted to
point out that there is something relevant, likely be part of an upcoming
standard so one should have it in mind. Sorry for not being explicit enough
in the first place ;)

> The upcoming SPARQLstandard doesn't define any class for named graphs.

Not yet. Any news from this end, Greg?

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

I'd suggest you forget about both  references and go with the upcoming
SPARQL standard [1].

I could dereference this and find it's meaning.

I could not dereference this.

So a: is the one to use.
