There are high expectations for Linked Government Data—the practice of publishing public sector information on the Web using Linked Data formats. This slideset reviews some of the ongoing work in the US, UK, and within W3C, as well as activities within my institute (DERI, National University of Ireland, Galway).

  • Data.Gov.UK has now released the RDF dumps that I sought. Thus, case closed re. my earlier quibbles :-)

    BTW - did you actually look at the data.gov.uk mailing list thread re. this issue of RDF dumps (again nothing to do with a specific RDF format) to get some background to my gripe before drawling conclusions about my comments?

    Links:

    1. http://bit.ly/bnp1Xy -- data.gov.uk mailing list thread re. issue of LOD and RDF dumps (note: the responses I’ve received to date) .

  • @cygri:

    Look, you know I don’t have a preferred format for anything when it comes to structured linked data. That isn’t my point. Also, my comments have nothing to do with undermining the good work. My gripe (an one I will not let up on) is this: at the onset of LOD (remember the SWEO project) we agreed the following best practices for 'open data' published as 'linked data':

    1. Produce an RDF dump
    2. Load into SPARQL compliant RDF Store
    3. Publish Linked Data (via whatever platform does the job for you)
    4. Link to other Datasets in the Linked Data Cloud.

    Also recall, we established that crawlers shouldn’t go pounding public SPARQL endpoints (since this ultimately disrupts other users), hence point #1.

    If you take some time to research the history of this gripe of mine (see the data.gov.uk mailing list), I am sure you will find the responses I’ve received so far quite intriguing.

    I hope I’ve made my point crystal clear?

    Please do remember, we do not exist in an 'all or nothing' realm (at least I don’t). When I raise concerns about practices that ultimately lead to confusion, the gut reaction simply cannot be: You Don’t Like This etc.. I am raising a very serious point here.

    How come Data.Gov have no problem producing RDF dumps (again nothing to do with a specific format, its RDF data in the format they have chosen).

The State of Linked Government Data The State of Linked Government Data Presentation Transcript

  • The State of Linked Government Data
    Richard CyganiakDERI Friday Talk, August 20, 2010
    http://linkeddata.deri.ie
  • High expectations …
    Publishing Public Sector Information on the Web
    Itenables the reuse of the data provided by government agencies, opening up new business opportunities.
    It provides citizens a direct access to public services, helping to cut costs and improve processes in the government agencies and between the agencies and the citizens.
    It helps increase the citizen engagement and participation
    Highest-profile adoption of Semantic Web tech to date
  • Open Data vs. Linked Data
    Open Data
    Equal access for all
    Licensing, legal issues
    Transparency
    Changing the way government works
    Linked Data
    URIs, HTTP, RDF, SPARQL, FOAF
    Linked, Open Data!
  • Open Data …
    Open Data starts with making available the data that you already have, in whatever format.
  • Raw data catalog, data.gov
  • Government data catalogs
    http://datos.fundacionctic.org/sandbox/catalog/map
  • TimBL’s 5-starplan for open data
    ★ Make your stuff available on the Web
    ★★ Make it available as structured data(e.g., an Excel sheet instead of image scan of a table)
    ★★★ Use a non-proprietary format(e.g., a CSV file instead of an Excel sheet)
    ★★★★ Use linked data format(i.e., URIsto identify things, and RDF to represent data)
    ★★★★★ Link your data to other people’s data to providecontext

    LOD2 IP
    Work package: National datasets on Austria, Germany, Ireland etc.
  • Reality check
    “Triplification” alone is not very useful
    Linked Data addresses syntax, data model, access, but does not automatically solve the hard problems
    Standardized classifications; identifier management; data provenance; versioning; context; data discovery
    Linked Data needs developers, journalists, analysts, scientists to translate it into benefits for the common citizen
    LD removes some technical issues, giving us a better shot at solving the organizational/political ones
  • And finally…
