  • The new CSV on the Web Working Group is an important step in that direction, following on the heels of efforts such as R2RML. It’s about providing metadata about CSV files, such as column headings, data types, and annotations, and, with it, making it easily possible to convert CSV into RDF (or other formats), easing data integration

Help:Using SPARQL and RDF stores - semantic-mediawiki.org - 0 views

  • In SMW 1.6.0, stores are required to accept updates and queries that do not specify a graph but it is planned to remove this limitation in the future.
  • The first line tells SMW to use the SPARQL store implementation to store data (instead of the SMWSQLStore2 that is the default). The remaining lines provide the relevant service locations, where the last line can be omitted if not applicable. By default, SMW will use a generic SPARQL connector that is based on recent SPARQL documents. Some RDF databases might not be fully compatible with this or might need special tweaks to make use of advanced, non-standard features. For this purpose, it is possible to change the SPARQL connector that SMW uses by setting the variable $smwgSparqlDatabase. In SMW 1.6.0, there is only one special connector:
  • $smwgSparqlDatabase = 'SMWSparqlDatabase4Store';

  • Missing experience regarding performance and stability: There are a number of industry-strength RDF databases available today, some of them free/open source. Yet, the experience of using these systems with SMW are still limited, so some testing is needed before deciding on a particular backend for a large-scale SMW application.
  • no named graphs are used in SMW queries
  •  
    By default, SMW stores all data in the MySQL database that is used by MediaWiki. This ensures a simple setup but it is not an ideal solution for the data format and data access methods that SMW needs. A more natural data model for SMW data is RDF, a data format that organizes information in graphs rather than in fixed database tables. It is possible to use such systems in addition to the SQL database for managing SMW data and for answering queries. This page explains the details

SPARQL 1.1 Query Results JSON Format - 0 views

  •  
    SPARQL is a set of standards for the query and update of RDF data, along with ways to access such data over the web. This document describes the representation of SELECT and ASK query results using JSON.

Extension:SparqlExtension - MediaWiki - 0 views

      Try Anzo!!!
  •  
    This extension allows one to integrate Semantic MediaWiki with a SPARQL endpoint via a web-service. While this has been set up and tested to work with Joseki and Jena TDB, the configuration is generic enough to make it work with any other standard-compliant SPARQL endpoint. We are especially interested in hearing your experiences using the extension with other SPARQL endpoints.

Speech on Building Britain's Digital Future | Number10.gov.uk - 0 views

  • A transcript of a speech given by the Prime Minister on Building Britain’s Digital Future in London on 22 March 2010.
  • Underpinning the digital transformation that we are likely to see over the coming decade is the creation of the next generation of the web - what is called the semantic web, or the web of linked data. This next generation web is a simple concept, but I believe it has the potential to be just as revolutionary - just as disruptive to existing business and organisational models - as the web was itself, moving us from a web of managing documents and files to a web of managing data and information - and thus opening up the possibility of by-passing current digital bottlenecks and getting direct answers to direct requests for data and information. It will change fundamentally the way we conduct business - with new enterprises by-passing traditional media communications and governmental organisations: new enterprises spun off from the new data, information and knowledge that flows more freely. And in both the content and delivery of public services the next stage of the web will transform the ability of citizens to tailor the services they need to their requirements, to feedback constantly on their success, to interact with the professionals who deliver them and to put the citizen not the public servant in control. Today I can announce the first funding for the next stage of this research - £30m to support the creation of a new institute, the institute of web science - based here in Britain and working with government and British business to realise the social and economic benefits of advances in the web. It will assemble the best of world scientists and researchers and be headed by Sir Tim Berners Lee, the British inventor of the world wide web - and the leading web science expert Professor Nigel Shadbolt. This will help place the UK at the cutting edge of research on the semantic web and other emerging web and internet technologies, and ensure that government is taking the right funding decisions to position the UK as a world leader. And we will invite universities and private sector web developers and companies to join this collaborative project.

  • it will enrich our democracy by giving people new ways of communicating complaining and challenging vested interests.
  • we must use this technology to open up data with the aim of providing every citizen in Britain with true ownership and accountability over the services they demand from government.
  • Building on the outstanding work Sir Tim and Nigel Shadbolt who have been leading on ‘making public data public’, I can now announce that we are determined to go further in breaking down the walled garden of government, using technology and information to provide greater transparency on the workings of Whitehall and give everyone more say over the services they receive.
  • Revitalising our politics, our governance and our democracy means going beyond simply increased openness about previously secret information - it requires the policy-making monopoly of ministers and the civil service to be challenged - where practicable - through a step change in the opportunities for people to engage with and interact with government in its policy proposals.

PLoS Computational Biology: Adventures in Semantic Publishing: Exemplar Semantic Enhanc... - 1 views

  • Scientific innovation depends on finding, integrating, and re-using the products of previous research. Here we explore how recent developments in Web technology, particularly those related to the publication of data and metadata, might assist that process by providing semantic enhancements to journal articles within the mainstream process of scholarly journal publishing. We exemplify this by describing semantic enhancements we have made to a recent biomedical research article taken from PLoS Neglected Tropical Diseases, providing enrichment to its content and increased access to datasets within it. These semantic enhancements include provision of live DOIs and hyperlinks; semantic markup of textual terms, with links to relevant third-party information resources; interactive figures; a re-orderable reference list;

A Declaration of the Independence of Cyberspace - 1 views

  • These increasingly hostile and colonial measures place us in the same position as those previous lovers of freedom and self-determination who had to reject the authorities of distant, uninformed powers. We must declare our virtual selves immune to your sovereignty, even as we continue to consent to your rule over our bodies. We will spread ourselves across the Planet so that no one can arrest our thoughts. We will create a civilization of the Mind in Cyberspace. May it be more humane and fair than the world your governments have made before.
  • Cyberspace consists of transactions, relationships, and thought itself, arrayed like a standing wave in the web of our communications. Ours is a world that is both everywhere and nowhere, but it is not where bodies live. We are creating a world that all may enter without privilege or prejudice accorded by race, economic power, military force, or station of birth. We are creating a world where anyone, anywhere may express his or her beliefs, no matter how singular, without fear of being coerced into silence or conformity. Your legal concepts of property, expression, identity, movement, and context do not apply to us. They are all based on matter, and there is no matter here.
