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. However, unlike the web of hypertext, where links are relationships anchors in hypertext documents written in HTML, for data they links between arbitrary things described by RDF,. The URIs identify any kind of object or concept. But for HTML or RDF, the same expectations apply to make the web grow: 1. Use URIs as names for things 2. Use HTTP URIs so that people can look up those names. 3. When someone looks up a URI, provide useful information. 4. Include links to other URIs. so that they can discover more things.

MyThreads-Links is a flexible web based links manager that looks similar to Yahoo but was written in PHP and uses MySQL. MyThreads-Links uses PHPLib Templates so that its very simple for anyone to change the look and feel of the program without having to edit the code.

So far little awareness exists about the commercial opportunities of linked data. Andreas Blumauer (SWC) talked to Chris Bizer, mastermind behind the DB-Pedia project and advocate of the linking open data philosophy, about the emerging market for deep web applications, its value for corporate purposes, and the need for information accountability and privacy awareness.

Triplify is based on the definition of relational database queries for a specific Web application in order to retrieve valuable information and to convert the results of these queries into RDF, JSON and Linked Data. Experiences showed that for most web-applications a relatively small number of queries (mostly between 3-7) is sufficient to extract the important information. After generating such database views the Triplify software can be used to convert the view into an RDF, JSON or Linked Data representation, which can be shared and accessed on the (Semantic) Web.

Linked Data is a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data on the Semantic Web. The practice emphasizes Web access to data using existing Web technologies such as URIs and HTTP. It also emphasizes links between related Web resources.

The Web is ephemeral. Pages change frequently, and it is nearly impossible to find data or follow a link after the underlying page evolves. We present Zoetrope, a system that enables interaction with the historical Web (pages, links, and embedded data) that would otherwise be lost to time. Using a number of novel interactions, the temporal Web can be manipulated, queried, and analyzed from the context of familar pages. Zoetrope is based on a set of operators for manipulating content streams. We describe these primitives and the associated indexing strategies for handling temporal Web data. They form the basis of Zoetrope and enable our construction of new temporal interactions and visualizations.

The Flamenco search interface framework has the primary design goal of allowing users to move through large information spaces in a flexible manner without feeling lost. A key property of the interface is the explicit exposure of category metadata, to guide the user toward possible choices, and to organize the results of keyword searches. The interface uses hierarchical faceted metadata in a manner that allows users to both refine and expand the current query, while maintaining a consistent representation of the collection's structure. This use of metadata is integrated with free-text search, allowing the user to follow links, then add search terms, then follow more links, without interrupting the interaction flow.

I hope that "Smarter" is going to be a key tag for the Web 3.0, and yet I think "More Open, More Ubiquitous, with even More Information (Overload) and a little Smarter" is what it's really going to be. We'll have to wait till "Web 4.0" for a web that really is stepwise more intelligent, one that could really be called semantic and hold the hidden promises of a "Semantic Web". And the reason I believe this is that the community is focused on linking more stuff together in new ways and breaking down data siloes, much more than it is focused on creating new, smarter filters for all the data that's going to be made accessible that way.

Control information overload. Emails, links, attachments, blog posts, news-all relevant data is organized and prioritized by contact.

Linked Environments for Atmospheric Discovery (LEAD) makes meteorological data, forecast models, and analysis and visualization tools available to anyone who wants to interactively explore the weather as it evolves. The LEAD Portal brings together all the necessary resources at one convenient access point

I'm fascinated with the way that a bunch of old ideas floating around from the dot com era are back, and now succeeding. Many of these apps are explicitly social, and are benefitting from the larger user population and increased comfort - it took quite a while for Match.com to catch on, and sixdegrees had much of the Friendster model down by 1996 and flamed out anyway. One really interesting category of these v 2.0 apps is shared bookmarking, a la the service Backflip from Back in the Day. So, with a minimum of editorializing, here is a list of places doing some form of shared link management, which are providing some of Tom Coates' "user-friendly throw-aroundable clumps of groupness."

The Historical Event Markup and Linking project provides a means of coordinating and navigating disparate historical materials on the internet. It includes 1. an XML schema for historical events which describes the events' participants, dates, location and keywords; the schema associates these with source materials in print or on the web. 2. XSLT stylesheets that combine conforming documents and generate lists, maps and graphical timelines out of them. Heml integrates these resources using the Cocoon2 web publishing engine.

Triplify provides a building block for the semantification of Web applications. Triplify is a small plugin for Web applications, which converts database content into RDF or JSON feeds and provides a Linked Data interface.

OpenSocial's API reference describes a number of classes ('Person', 'Name', 'Email', 'Phone', 'Url', 'Organization', 'Address', 'Message', 'Activity', 'MediaItem', 'Activity', …), each of which has various properties whose values are either strings, references to instances of other classes, or enumerations. I'd like to make them usable beyond the confines of OpenSocial, so I'm making an RDF/OWL version. OpenSocial's schema is an attempt to provide an overarching model for much of present-day mainstream 'social networking' functionality, including dating, jobs etc. Such a broad effort is inevitably somewhat open-ended, and so may benefit from being linked to data from other complementary sources.

WikiProteins enables community annotation in a Wiki-based system. Extracts of major data sources have been fused into an editable environment that links out to the original sources. Data from community edits create automatic copies of the original data. Semantic technology captures concepts co-occurring in one sentence and thus potential factual statements. In addition, indirect associations between concepts have been calculated. We call on a 'million minds' to annotate a 'million concepts' and to collect facts from the literature with the reward of collaborative knowledge discovery. The system is available for beta testing at http://www.wikiprofessional.org

This poster presents ongoing efforts to enrich the RDF-based semantic Web with the tools of the Historical Event Markup and Linking Project (Heml). An experimental RDF vocabulary for Heml data is illustrated, as well as its use in storing and querying encoded historical events. Finally, the practical use of Heml-RDF is illustrated with a toolkit for the Piggy Bank semantic browser plugin.

The Sematic Web Client Library represents the complete Semantic Web as a single RDF graph. The library enables applications to query this global graph using SPARQL- and find(SPO) queries. To answer queries, the library dynamically retrieves information from the Semantic Web by dereferencing HTTP URIs and by following rdfs:seeAlso links. The library is written in Java and is based on the Jena framework.

The NeuroCommons project seeks to make all scientific research materials - research articles, annotations, data, physical materials - as available and as useable as they can be. We do this by both fostering practices that render information in a form that promotes uniform access by computational agents - sometimes called "interoperability". We want knowledge sources to combine meaningfully, enabling semantically precise queries that span multiple information sources. Our work covers general data and knowledge sources used in computational biology as well as sources specific to neuroscience and neuromedicine. The practices that we develop and promote are designed to play well on the Semantic Web. We view our technical work not as creating a new service or content library, although we do both, but rather as helping to promote the growth of semantically linked scientific information.
