The USA and UK governments have made significant progress with linked, open data in recent months. Several fundamental datasets from the Australian Government are on the cusp of being exposed as meaningful, reusable, machine-readable assets, further driving the adoption of linked data within and around government.Making better use of online data offerings using a combination of top-down policy and guidance, together with bottom-up development efforts from agency web teams, would seem to describe a sustainable, organic growth in linked government data.Learn about the path to the first release of data.gov.au; a draft roadmap to future releases; the barriers to linked data and open public sector information (PSI); and the real-world questions this technology aims to solve.
About Gordon Grace
Based in the Australian Government Information Management Office (AGIMO), Gordon has been working on whole-of-government websites and Australian Government web policies since early 2006.Gordon likes making attractive, useful things that matter to people. He’s some thing of a ‘plate spinner’, and likes to punish himself by taking on too many projects at once. Gordon can often be found prodding and lifting dirty great big IT systems over usability, accessibility and standards-compliance hurdles, gently preparing them for the hostile, unforgiving and unpredictable web.Gordon lives in Canberra with his wife and two young children, who are rarely hostile, frequently forgiving, and always unpredictable.Follow Gordon on Twitter:@gordongrace

Libraries contain masses of beautifully structured data collected over many years. But these records may have their flaws and might now want to be used in ways, such as location based services, that weren't imagined 30 years ago. How can we use existing API's and web services to enrich this data to enable it to be used in a variety of ways. This data also needs to be exposed for others to use and build upon. With the recent release of the Government response to the Web 2.0 taskforce, how can institutions comply with these recommendations by providing their data in usable forms for the public. What's involved in building an API into our resources and how can our data be given more meaning through semantic linkages like RDFa?
About Paul Hagon
Paul is the Senior Web Designer at the National Library of Australia and has been working on the web in cultural institutions since 1999. His job entails a mix of design, coding, and accessibility. He is a thinker and "ideas" man. He finds cultural institutions fascinating because of what they bring to society, they are rich resources of information and provide vast potential for exploring hidden treasures. Paul enjoys making these items available and telling their stories in ways that may not be the most obvious. He likes to use technology in a relevant way to enrich the way we can interact with these resources.In 2010 Paul was named a "Mover and Shaker" of the library world by Library Journal.Follow Paul on Twitter:@paulhagon

RDFa is a W3C standard for embedding semantic metadata directly into HTML web pages. While early work on RDFa dates back to 2004, it recently gathered a lot of uptake and traction through the adoption by big players such as Google, Yahoo! and Facebook. This has put the Semantic Web into the attention of a much wider public, setting RDFa out the be the technology to finally bring the Semantic Web into the mainstream. The language gained the status of a W3C recommendation in late 2009 as RDFa 1.0. Since then, the RDFa working group has been established to improve and extend the standard. Eventually, this work will result in a new version of the language, which is set to be released as RDFa 1.1 in 2011. In this talk, an overview will be given of the RDFa technology in general, followed by an outline of its latest developments, such as the RDFa API, or the definition of RDFa Core, which prepares the standard to extend its scope beyond the context of web pages, by allowing it to be included into any other markup language than just HTML.
About Knud Möller

When people use websites and intranets they are doing more than just ‘finding’ information. They may be looking for something they know about or exploring something brand new; filtering through large volumes then comparing results; getting an overview of a topic or diving deep. They may even think they want to find one thing, but actually need something entirely different.Each of these information behaviours needs very different approaches to information architecture, information design and page layout. During this presentation, Donna will talk about each information behaviour, its key attributes, key design needs, and show good and bad examples of each.

Can web-based social systems with their wide reach, user-generated and user-filtered content harness the wisdom of crowds? Duncan Watts’ recent experiments reveal how popularity based web social systems can throw up fickle, random trends that are essentially unreplicable, and only tangentially related to quality. However, popularity as a way to filter information continues to rise in popularity - replacing hierarchical menus, overtaking tags, and even used in lieu of relevance. Rashmi will link decades of psychology research on group decision making and social influence to what is happening on the web today. She will discuss different models of popularity based filtering such as Digg and YouTube. What are ways to avoid the Watts dilemma - including Google’s model of sociality, tag-based social systems, and object-based social networks. She will present some principles for the design of web social systems and how there were used in the design of SlideShare and discuss how SlideShare as an evolving social system handles popularity.
Rashmi Sinha is a designer, researcher and entrepreneur. She is the CEO for SlideShare, a rapidly growing site for sharing slideshows. Rashmi writes a blog at rashmisinha.com.
Rashmi received a PhD in cognitive psychology from Brown University in 1998. After moving to UC Berkeley for a PostDoc, she fell in love with the web, and realized that many issues that web technologists think about are problems of human psychology. She switched departments and worked on search interfaces & recommender systems at the Information School, UC Berkeley. Deciding that she enjoyed practical problems more, she co-founded Uzanto, a user experience consulting company. Lately Uzanto has focused on products - their first product MindCanvas (released Nov 2005) - reshapes traditional research techniques like card-sorting, and divide-the-dollar into game-like experiences for remote research. In Oct 2006, Uzanto released its second product - Slideshare, a website for sharing presentations. Now, Rashmi is focused on the business side of things but is still intimately involved with design for both products.

There are 2 aspects to making IA work in a project - an understanding of the key principles of information architecture and a knowledge of activities to put them into practice. This presentation will examine the "how to's" of information architecture. We'll look at how to take a content inventory, analyse content, conduct card sorting, analyse user research, choose the right structure, create an information architecture and test it. These activities drive an informed design process so you can be confident in your decisions and communicate them to other people.
