Linked Data - Design Issues
The Semantic Web isn't just about putting data on the web. It is about making links, so that a person or machine can explore the web of data. With linked data, when you have some of it, you can find other, related, data. Like the web of hypertext, the web of data is constructed with documents on the web.

the Web Audio API and MediaStream Processing API specifications each define a different approach to process and synthesize audio streams directly in script. These APIs can be used for interactive applications, games, 3D environments, musical applications, educational applications, and for the purposes of accessibility. They include the ability to synchronize, visualize, or enhance sound information when used in conjunction with graphics APIs. Audio Processing API introduces and compares two client-side APIs for processing and synthesizing real-time audio streams in the browser. Read the blog post Sounding Out the Audio APIs for more information about the possibilities unlocked by an audio API, and learn more about the Rich Web Clients Activity . The RDF Web Applications Working Group has published a Working Draft of RDFa Core 1.1 , a specification for attributes to express structured data in any markup language.

How DBpedia Treats Wikipedia as a Database - ReadWriteCloud
This post is part of our ReadWriteCloud channel, which is dedicated to covering virtualization and cloud computing. The channel is sponsored by Intel and VMware . Read the case study about how Intel Xeon processors and VMware helped virtualize 12 business critical database applications . DBpedia is a community driven effort that treats Wikipedia like a database, enabling people to do more sophisticated queries, distribute the open encyclopedia's data to the Web and add back to Wikipedia for the purposes of enriching it. In a blog post this week , the community showed again what makes the service a unique effort with the launch of the latest version of the technology.

Yesterday I gave a short talk at Online Information 2010 titled “Challenges and Opportunities for Linked Data” ( abstract ). The presentation highlighted what I saw as the main challenges that face us as we grow the web of data, and highlighted some opportunities for organisations that want to get involved. I believe there will be video from the various presentations online at some point, but wanted to post a transcript of what I said (or had planned to say!).How does the emergence of the semantic web and its associated technologies change the way we approach user experience design and more specifically information architecture? In Tim Berners Lee’s original proposal for the web he gave us the basic ingredients to build the web of documents as we experience it today. This gave us a easy means to publish documents, refer to them with url’s and point from one document to another with a hyperlink. In many ways the web became a victim of its own success. The simplicity with which we could publish documents meant we were soon overwhelmed. At this point Information Architects were employed to group together documents into managable piles.
How the emergence of the semantic web changes the way we think about information architecture. : block, slab, pillar
If Sir Tim Berners-Lee can equate Linked Data with a packet of crisps /potato chips, I thought I would take a stab at another food metaphor for this post. Linked Open Data (LOD) is a concept that many believe they understand. Take yourself to most any conference that has a connection with data, or the web, or the Internet at the moment, and it will not belong before you see a slide of the Linked Open Data cloud diagram, or of Sir Tim imploring us to give him our raw data now , or if you are very lucky a shot of him doing his imploring whilst stood in front of a shot of the LOD cloud. - Simple really, just publish your data as L inked O pen D ata and all will be wonderful as we move towards the sunlit Semantic Web uplands. Unfortunately life is never that simple – LOD is not a single identifiable thing. As Paul Walk eloquently puts it :

DBpedia is a project aiming to extract structured content from the information created as part of the Wikipedia project. This structured information is then made available on the World Wide Web . [ 2 ] DBpedia allows users to query relationships and properties associated with Wikipedia resources, including links to other related datasets . [ 3 ] DBpedia has been described by Tim Berners-Lee as one of the more famous parts of the Linked Data project. [ 4 ] [ edit ] Background The project was started by people at the Free University of Berlin and the University of Leipzig , in collaboration with OpenLink Software , [ 5 ] and the first publicly available dataset was published in 2007.

In a conversation with data owners about how they should be publishing their data, it is usually not long before the following question turns up: “ So, what do I actually have to do to publish my data? ” Often the conversation then wanders off into a game of buzzword bingo–RDF, RDFa, SPARQL, dereferenceable URIs, triples, content negotiation, open data, Linked Data, end-points, etc.—to be followed by a blank look and the unuttered question " Yes, but what do I actually have to do to publish my data? ”

This may be of limited interest, but the Linked Data on the Web workshop [1] going on now at WWW2010 has a short paper by Bernhard Schandl about making file systems available as linked data:In May last year we wrote about the state of Linked Data , an official W3C project that aims to connect separate data sets on the Web. Linked Data is a subset of the wider Semantic Web movement, in which data on the Web is encoded with meaning using technologies such as RDF and OWL. The ultimate vision is that the Web will become much more structured, which opens up many possibilities for "smarter" Web applications. At this stage last year, we noted that Linked Data was ramping up fast - evidenced by the increasing number of data sets on the Web as at March 2009. Fast forward a year and the Linked Data "cloud" has continued to expand.
The State of Linked Data in 2010
From Annual2009 In addition to programs sponsored by divisions, round tables and committees, this year's Annual Conference features 10 "Grassroots Programs" selected by a jury of library school students and practitioners from 118 proposals. These Grassroots Programs are part of ALA president Jim Rettig's presidential initiative to increase opportunities for members to participate in, contribute to and benefit from their association. The purpose of this initiative has been to broaden opportunities for ALA members to present programs at the Annual Conference and to compress the planning schedule to accommodate programs on very current issues.

This document provides a tutorial on how to publish Linked Data on the Web. After a general overview of the concept of Linked Data, we describe several practical recipes for publishing information as Linked Data on the Web. This tutorial has been superseeded by the book Linked Data: Evolving the Web into a Global Data Space written by Tom Heath and Christian Bizer. This tutorial was published in 2007 and is still online for historical reasons. The Linked Data book was published in 2011 and provides a more detailed and up-to-date introduction into Linked Data.
