    Politics, Communities & Data

    by Phil Archer

    Relevant technology area: Semantic Web.

    Abstract:
    Research data, cultural heritage data, government data - you know it's all the same, right?

    Abstract:
    The World Wide Web was conceived as a means of social interaction to share knowledge, and developed initially as a "Web of Documents", creating "islands of information". Now the Web is evolving towards a "Web of Data", in which machines can perform connection between the resources available on the web, thanks to the technological infrastructure of the Semantic Web. The basic technology is RDF (Resource Description Framework) which implements a totally decentralized mechanism to describe the relationships between the resources available on the Web. Therefore RDF allows you to publish data on the Web, making them available for remote queries, possibly involving data sources distributed on various sites, thus implementing the paradigm of Linked Open Data at its highest level. But the real glue of the Semantic Web are ontologies, designed as a formal representation of reality and knowledge representation mechanism in a distributed environment. The seminar will outline briefly the basic technologies of the Semantic Web and the principles of Linked Open Data.

    Abstract:
    The Web was conceived 26 years ago to solve a complex problem: how to allow communication between different research teams using different systems to run and document different experiments. Of course it has evolved enormously since then. HTML5 is just the centerpiece in a network of technologies that form a globally available operating system available on every connected device. It's interactive, it's powerful, it's fascinating and, at times, it's dangerous. And the Web isn't just about documents, images and videos. It's a web of data. Product data, government statistics, geographic data and more. A lot of this data is available for free – after all, so much of what is online is free – but all too often, you get what you pay for. In this talk, W3C Data Activity Lead, Phil Archer, will look at how Web technologies are being applied in areas like automotive, social Web, graphics and geospatial, and how the technologies and concepts that have made the Web so successful can be harnessed to build the Web of data.

    GIS and the Web – what's the problem?

    by Phil Archer

    AGILE 2015

    Lisbon, Portugal

    Relevant technology area: Semantic Web.

    Abstract:

    The standards that underpin geospatial data all use Web technologies, notably XML which first became a W3C standard on 10 February 1998. So how come integrating geospatial data with other data on the Web is so hard and often requires manual intervention? Web applications often need to access small parts of multiple large datasets, search engines need to match unstructured text on the Web with locations, data publishers have a lot of choice in how they share their data but which of the many available standards is best for a given context? These problems and more arise at least in part from the difference in culture between the geospatial world in which the primary reference is to a point, line or polygon, and the Web where the primary reference is the identifier, the URI, of a document, a concept, a building or a data point - one property of which might be a location.

    A workshop on this topic organised by the EU's SmartOpenData project in March 2014 lead directly to a collaborative effort between the two key standards bodies: the World Wide Web Consortium (W3C) and the Open Geospatial Consortium (OGC). W3C's Data Activity Lead, Phil Archer, will reflect on the problems that have been identified and what needs to be done if the two ecosystems are to benefit from each other's data.
