OpenStreetMap is creating a free geowiki of the world, primarily street maps at present. Why? Geodata generally isn't free or available.

Platial is an initiative to create a collaborative atlas that bridges people, neighborhoods and nations and enables people to document experience through geography. When geography can viewed through the eyes of many, geopolitical boundaries begin to melt.

StreamOnTheFly is an open source and open content media network, fed by community radio stations, which allows easy exchange of content for broadcasting and podCasting.

The Internet is not the only source of open data. This session will look at what happens when you realise that Digital Broadcasts are just nicely structured APIs. It will include demos of some internal BBC prototypes.

A BBC Radio project developing a wiki-like interface for collaboratively chopping up radio programmes into segments and annotating and tagging each segment.

This talk discusses the requirements for Web Applications, and the underpinnings necessary to make Web Applications follow in the same spirit that engendered the Web in the first place.

Our digital selves are being increasingly surveilled, tracked and controlled by government and business alike, while our rights to privacy and free speech are eroded. What are the most worrying threats, and how you can protect your digital rights?

Open data is not a panacea, and presents as many questions as answers. Technology can only solve some of these issues, this presentation outlines some of the other, more fundamental, problems.

What are the architectural elements of the emerging web of data; how do you build services to thrive in this environment? What needs to change and what needs to return to fundamental principles? How do we bring it all together to make something awesome?

Thomas will explain his Model of Attraction, to frame the constraints of developing across devices and platforms. He will use his Personal InfoCloud to frame digital information convergence for the person so to design our information for use and reuse.

XML-based open standard vocabularies are rapidly developing in - not across - many vertical domains. Where is the common ground, and what can be gained by standardization? What works and what doesn't in building vocabularies?

The National Archive of Australia was one of the first govt agencies in the world to adopt XML formats for the digital preservation of documents. This presentation examines Australia's part in the Open Source, Open Data, OpenDocument ecosphere.

This presentation describes Connotea, an experimental service that marries social bookmarking and tagging with existing academic information tools. It also highlights a challenge - how best to link web resources to data about those resources.

A look at ways of enriching user experience of complex data sets, through taxonomy, visualization, imagery and interaction

Embedded RDF is a pattern for enriching content by interweaving existing XHTML markup with RDF. The method used requires no new markup so the XHTML can still be validated, is fully CSS compliant and will not affect browser behaviour.

With the huge potential of GeoRSS to leverage the "RSS Ecosystem" for the Geospatial Web, GeoRSS.org was created with the goals of promoting interoperability, upwards compatibility with GML, and extending W3C geo for line and polygon geometries.

This paper will discuss tagging unplugged from the tagging services that build them using a series of RDF models to ask 'What is imporant about a tag?' and providing ways to go from the tags to what people think they are about.

Does application-aware networking threaten the "open internet" - where every message is handled equally? Ironically, the very power unleased by exchanging XML on the internet threatens, in the eyes of some, Web 2.0 goals of openness and innovation.
