AKSW presentation at LinkedDataPlanet in NYC

Posted on May 6, 2008 by Sören Auer

Sören will give a presentation “From DBpedia to OntoWiki – Emergent Data and Semantics from Social Collaboration” at this years LinkedDataPlaned Conference & Expo on June 18, 2008 at the Roosevelt Hotel in New York City. The presentation will cover AKSW’s current work regarding social semantic collaboration (i.e. DBpedia and OntoWiki) and light-weight technologies aiming to overcome the chicken-and-egg problem of the Semantic Web (such as Triplify). If you are at the East Coast in June consider joining us for the LinkedDataPlanet and meeting other LinkedData protagonists such as Tim Berners-Lee, Kingsley Idehen and Ian Davis. For those on a tight budget SWC is awarding a free conference pass (worth $1095) or email Sören (for a guest pass).

Joomla! triplification starts as Google Summer of Code project

Posted on April 22, 2008 by Sören Auer

Danh Le Phouc (a computer science PhD student from DERI Galway) is starting the Google Summer of Code project “Joomla! semantification – expose Joomla data as RDF and Linked Data”. Danh already created a first guess for a Joomla! Triplify configuration (available at http://triplify.org/Configuration/Joomla)). Work of the project will focus on tighter integrating Triplify into Joomla! and showcasing the benefits of of the Joomla! triplification to the user community. The GSoC project is mentored by Sören.

LOD Triplification Challenge

Posted on April 9, 2008 by Sören Auer

Together with this years I-Semantics conference we are organizing a Linking Open Data Triplification Challenge.

The challenge aims at expediting the process of revealing and exposing structured (relational) representations, which already back most of the existing Web sites, as well as raising awareness in the Web Developer community and showcasing best practices.

The challenge awards attractive prices (MacBook Air, EeePC, iPod) to the most innovative and promising semantifications. The prizes are kindly sponsored by OpenLink Software, Punkt.NetServices and InfAI.

More Information about the challenge can be found at:

http://triplify.org/Challenge

Outreach to the Web developer communities (as intended with the challenge) is really crucial right now to expedite the Semantic Web deployment and we would be very excited if you support this effort – e.g. by spreading the word and/or submitting to the challenge.

Triplify 0.3 released

Posted on April 9, 2008 by Sören Auer

We just release a new version of our Web application plugin Triplify, which exposes structured data from relational databases as Linked Date, RDF, and JSON. This release contains a number of bugfixes and impovements. Most notable the compatibility with PHP4 was improved and the possibility to add meta-data to your RDF added.

These are the changes in V0.3 (08-04-2008):
* added owl:imports statement importing the vocabulary
* added rdfs:comment about generator
* configuration variable “register” added
* Syntax for indicating objectProperties added:
SELECT id,user_id ‘sioc:has_creator->user’
* Configuration variable $triplify[‘cachedir’] added
* proper UTF8 encoding of literals added (thanks to Rolf Strathewerd)
* Configuration variable $triplify[‘license’] added
* Configuration variable $triplify[‘LinkedDataDepth’] added
* Configuration variable $triplify[‘metadata’] added
* Configuration variable $triplify[‘CallbackFunctions’] added

Triplification with Google's Summer of Code

Posted on March 25, 2008 by Sören Auer

We did not participate as a mentor this year in Google’s Summer of Code program. However, there seem to be some Triplify related projects appearing. The PHP Content Management System Joomla! for example aims at integrating Triplify within a GSoC project:

http://docs.joomla.org/Code_04000

Also the Drupal community is actively discussing to integrated Semantic Web and Linked Data interfaces such as Triplify. Probably also a number of other PHP related projects would be excited to see a Triplify integration. If you as a student are interested in participating and earning $5000 during the summer, just suggest a corresponding project to one of the GSoC mentors. But hurry, the application deadline ends March 31st.
BTW: You will also be eligible to participate in the Triplification Challenge we are currently preparing with the chance to win an MacBook Air, an EeePC or an IPod Touch.

Triplify – expose semantics!

Posted on March 16, 2008 by Sören Auer

Triplify logo

After a first preview release a couple of weeks ago we worked hard to prepare a first public release of Triplify. 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:

Triplify 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.

Triplify overview

Triplify 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.

Triplify makes Web applications easier mashable and lays the foundation for next generation, semantics based Web searches.

More infos, the software release, some example configurations for OpenConf, Open Journal Systems, WackoWiki, WordPress and Drupal are available from: http://triplify.org

Triplify 0.4 released

Posted on March 1, 2008 by Sören Auer

We just released version 0.4 of the Triplify script. After the initial release several months ago we made quite some additions and bug fixes the most important of which are:

  • Update log functionality added – allows Semantic Web crawlers to get incremental updates, see http://triplify.org/vocabulary/update
  • linked data publication now also works without Apache’s mod_rewrite
  • Syntax for indicating objectProperties added, e.g.:SELECT id,user_id 'sioc:has_creator->user'
  • Additional metadata can now be added via $triplify[‘metadata’]
  • The configuration variable $triplify[‘CallbackFunctions’] allows programmatic post processing of DB content

Triplify – technology preview

Posted on February 27, 2008 by Sören Auer

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.

The Triplify implementation and further information is available from the still preliminary web site at: http://triplify.org

Goodbye SourceForge …

Posted on February 25, 2008 by Sebastian Tramp

xOperator Logo
The xOperator Project is moved to Google Code which is much faster (the tracker, not the subversion repository) and has some nice features (e.g. the customizable grid view).

Traditionally we use SourceForge.net for our open source project management. 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).

Project resources of xOperator are now Issue Tracker, Downloads and Mailinglist (moved to google groups). Our homepage @ aksw.org does not move.
