Scripting languages play a central role in the development of flexible, lightweight semantic web applications. Hence, the workshop aims to bring together developers of the RDF base infrastructure for scripting languages with practitioners building applications using these languages. It includes a scripting challenge which will award a prize (an Apple iPod Video or alternatively Euro 200 cash) to the most innovative small scripting application or mashup. The workshop is co-located with 4th European Semantic Web Conference and takes place on June 6, 2007 in Innsbruck, Austria.

"Cofundos.org is a novel platform for spurring innovation and development of open-source software. It can have quite an impact on open-source and web collaboration in general: Cofundos.org is about revealing bright ideas regarding the development of open-source software and attracting a critical mass for their realization. The main idea of Cofundos.org is to share innovative (open-source) ideas, to refine them and to mobilize funding for their realization.\r\n\r\nThere exist now already a number of Web sites and services empowering its users to pool resources in order to achieve certain goals.\r\nPledgebank for example is a universal pledging service, whereas Fundable is a platform for goal-oriented fundraising.Change.org, tries to connect people concerned about certain causes with non-profit organizations that relate to them. And when it comes to widgets, ChipIn makes it easy to embed dynamic fundraising boxes into any website. There are a number of Facebook applications as well.\r\n\r\nMissing so far was a platform exploiting the power of many distinctively for open-source software development. This is the aim of Cofundos.org. The concept is based on the following principles:\r\n\r\n
    \r\n
  • Open-knowledge and open-source. All ideas and contributions on Cofundos are licensed under a Creative Commons Attribution License. All project outcomes must be licensed under an OSI approved open-source license.
    • \r\n
  • Reputation and community. Bright ideas and excellent solutions often originate from outstanding individuals. But it needs a community to mature these ideas and solutions and in order to bring the critical mass together for their realization.
    • \r\n
  • Fairness and trust. An open, accountable and transparent environment will foster fair communication and trustworthy relationships between its users.
    • \r\n
  • Big impacts can be achieved in small steps. Conceiving and realising bright ideas does not require many year developments or huge amounts of funding. Their realisation can be achieved by bringing together innovative ideas with clearly defined features and requirements based on community involvement and fostering their accomplishment by committed specialists.\r\n
    • \r\n
\r\n\r\nIn addition to these principles, Cofundus.org is entirely semantically interoperable - all (non-sensitive) content is accessible in the form of Atom, JSON feeds or as RDF export. Cofundos invites everybody to register or login using OpenId and to post software ideas, requirements or even bid for the realization of existing projects.\r\n\r\nCofundos is operated by the Agile Knowledge and Semantic Web research group (AKSW) at the Department of Business Information Systems at Universität Leipzig.

"\"xOperatorFresh from the subversion repository, our new semantic agent project xOperator is now able to play with my local OntoWiki knowledge bases. The initial development to this tool will be done by Jörg Unbehauen as part of his master thesis.\r\n\r\n
xOperator tries to create a decentralized network of trust. Information is shared in the form of resources, which can be anything (even the information that you are selling your old washing machine). In a later stage it enables you to find friends of friends like centralized services, can already. At the end of the road, xOperator might even be able to find the best product for you without the normally necessary tedious internet research. Companies will be able to offer semantic annotated information about their products, giving the customer a new way of yet unknown price transparency.
\r\n\r\n\r\n\"FirstAlthough xOperator is able to use any SPARQL endpoint out there, our main use case is to marry it with OntoWiki. Users should be able to use the agent just as an additional view to the knowledge bases of their OntoWiki installation.\r\n\r\nTo do this, it will be possible not only to ask the agent with special query languages like SPARQL but also to ask him with natural language. To achieve this, xOperator will map templates based on the Artificial Intelligence Markup Language (AIML) to SPARQL queries and transform the XML result set to the instant message which will be send back to the user.\r\n\r\n

Implementation Status

\r\n
The agent is able to log into existing accounts and can receive querying and configuration commands. The template based query generation is still a bit quirky. Queries can only be executed against locally configured data stores, the p2p part is not yet implemented.
\r\n\r\nIf you're interested in the project, please write to the public mailing list xoperator-public in our SourceForge area. The official homepage is http://aksw.org/Projects/xOperator" .

DL-Learner is a tool for learning complex classes from examples and background knowledge. It extends Inductive Logic Programming to Description Logics and the Semantic Web.\r\n\r\nDownloads are available at the sf.net project page. For a list of the most important changes since the last release (Build 2007-08-31), see the Changelog. Most notably, DL-Learner now has a flexible component based design, which allows to extend it easily with new learning algorithms, learning problems, reasoners, and supported background knowledge sources. A new type of supported knowledge sources are SPARQL endpoints, from which DL-Learner can extract knowledge fragments, which enables learning classes even on large knowledge sources like DBpedia. Furthermore, DL-Learner now supports learning from positive examples only, inclusion axiom learning, the usage of N-Triple files as background knowledge, the OWL API reasoner interface, and has a more powerful web service interface.

Scripting languages as PHP, JavaScript, Ruby etc. will play a crucial role for getting the Semantic Web out on a large scale and most of the really deployed Semantic Web applications (e.g. Semantic MediaWiki, DBpedia, Tabulator etc.) are implemented in scripting languages. The deadline for submitting papers to the workshop is March 7th. The workshop will also include a challenge, which awards an (iPod or the equivalent in cash) to the most promising lightweight Semantic Web Application developed in a scripting language.

"Triplify - technology preview" . "Solely for the reader community of the AKSW blog we have a technology preview, which we hope will increase the amount of semantics on the Web and maybe even provide the missing spark for a large scale deployment of semantic technologies on the Web. Triplify is a minimalistic technique to \"semantify\" Web applications by exposing information from their relational database backends as RDF, JSON and Linked Data. The required effort to do so is minimal - just some SQL queries selecting the information to be made available have to added to the Triplify configuration. Triplify cares about everything else.\r\n\r\nThe Triplify implementation and further information is available from the still preliminary web site at: http://triplify.org" .

SF is a great side and I'm member of 9 projects there but it was time to move. Basically its a matter of speed. I work every day on tracker items like bug reports, feature requests and tasks for one of our projects and the sf-page is very slow in comparison to google code and also in comparison to our tracker for commercial projects (we use mantis for that).\r\n\r\nProject resources of xOperator are now Issue Tracker, Downloads and Mailinglist (moved to google groups).

We fixed a number of bugs and added several additional features, some example configurations for popular Web applications were created and the Web site was completely overhauled: Michael Haschke created the new Triplify logo as well as the design and most other visuals on the site. For those who missed the first Triplify announcement:\r\n\r\nTriplify enables the effortless “semantification” of Web applications. Triplify is a small plugin for Web applications, which reveals the semantic structures encoded in relational databases by making database content available as RDF, JSON or Linked Data.\r\n\r\n\"Triplify\r\n\r\nTriplify is very light weight: It consists just of few files with less than 500 lines of code. For a typical Web application a configuration for Triplify can be created in less than one hour and if this Web application is deployed multiple times (as most open-source Web applications are) the configuration can be reused without modifications.\r\n\r\nTriplify makes Web applications easier mashable and lays the foundation for next generation, semantics based Web searches.\r\n\r\nMore infos, the software release, some example configurations for OpenConf, Open Journal Systems, WackoWiki, WordPress and Drupal are available from: http://triplify.org" .

I will give a talk about our xOperator project at the European Semantic Web Conference (ESWC2008) on Tenerife next Wednesday. The xOperator is an agent for xmpp / jabber network which queries and shares trusted resources (using RDF/SPARQL) for you and your jabber friends. In addition to the full paper, we got good reviews for the demo session too. So I present the xOperator in a more technical way at the demo session on Tuesday.

\r\n

Another project which we started here is RDFAPI-JS. I present this work at the Scripting for the Semantic Web Workshop (SFSW2008) which is co-located with the ESWC. RDFAPI-JS is used for RDFa widgets which can be used to modify embedded RDF models.

Thanks to Jörg, Martin and Seppl (and of course Haschek for the awesome poster) which helped me preparing the demo and the presentations. Sorry for this last week ... :-)
