LOD2 Plenary Meeting: WebID and Authorization SIG
Today morning, we started the main LOD2 plenary meeting in Vienna. The first half day session the WebID special interest group discussed about WebID based single sign for the LDO2 stack and authorization. The challenge here is to provide a interoperable authorization layer which describe user, groups / roles and access to different parts of the stack as well as the managed knowledge bases. We agreed on the following short and long-time goals and activities: WebID registration service and stack internal authorization policy.

Planet Federated Social Web Launched
Because we all like Planet RDF and the Federated Social Web Community does not have such a service at the moment, we’ve recently launched Planet Federated Social Web as a community service for the W3C Federated Social Web Incubator Group at http://planet-fsw.lod2.eu. We are working since several years on applications and protocols for distributed social [...]

OntoWiki 0.9.5 Available
The AKSW research group is pleased to announce that OntoWiki 0.9.5 is now available for download. OntoWiki is a web-application enabling the collaborative creation and (linked data) publication of RDF knowledge bases. More information about OntoWiki can be found at http://ontowiki.net. You can download OntoWiki in our google code file section. Enhancements in this release [...]

PatchR: Patch Repository > PatchR ontology
The Patch Request Ontology (pro) provides a straightforward method to share user feedback about erronious triples. By wrapping the UpdateInstruction-concept of the Graph Update Ontology (guo) a foaf:Agent can announce a patch request, i.e. publish requests to add, modify or delete certain facts from a certain dataset. Other actors can advocate or criticise or discuss a patch, which provides a minimum level of trust for automated procedures. Furthermore, an effective selection of patches is supported by providing appropriate metadata using the Provenance Vocabulary (prv) , the Vocabulary of Interlinked Datasets (void) and a tailored patch type-taxonomy (ldd). Therefore, the Patch Request Ontology helps to select appropriate updates on linked data resources and should support various usage scenarios in the area of data cleansing, error reporting and user feedback for semantic web applications.

PatchR: Patch Repository > home
The Web of Data is by no means a perfect world that consists of consistent and valid facts represented by RDF (Resource Description Framework) triples based on RDFS (RDF Schema) and OWL (Web Ontology Language) ontologies. Inconsistencies, ambiguities, confused or conflicting categorization systems, as well as pointless and futile facts need to be identified, reported and straightened out. Defects in linked datasets, e.g. semantic and factual errors are hard to detect in an automated manner. Furthermore, the revision of certain errors requires extensive processing of linked datasets. Therefore, we propose a general workflow to share updates between dynamically linked datasets.

Group and Interests

I am a member of the Agile Knowledge Engineering and Semantic Web (AKSW) Research Group.
My research interests are:

  • Basic Web information technologies (Web data integration, personalization techniques, architecture of Web information systems)
  • Semantic Web infrastructure and languages (query, rule and update languages)
  • Security / trust / privacy in the Semantic Web 
  • Semantic Web applications
  • Social networks and social impact of the Semantic Web 
  • Interfaces for the Social Semantic Web / Federated Social Web 
  • Directory Services

Research Projects

  • LOD2 – Creating Knowledge out of Interlinked Data (EU funded)
  • OntoWiki – Semantic Collaboration for Enterprise Knowledge Management, E-Learning and E-Tourism (EU funded)
  • LE4SW – Regionale Technologieplattform für soziale, semantische Kollaboratio (BMBF funded)
  • SoftWiki – Distributed, End-user Centered Requirements Engineering for Evolutionary Software Development (BMBF funded)

Open Source Software Projects

Beside these official projects, please refer to my bitbucket as well as my github profile.


  • OntoWiki – Semantic collaboration platform implementing the Web 2.0 idea of an architecture of participation for the collaborative development of Semantic Web knowledge bases
  • RDFauthor – is an editing solution for distributed and syndicated structured content on the World Wide Web.
  • Mobile Social Semantic Web – is an Android-based social web client as well as a contacts provider, which integrates your distributed FOAF/WebID social network into your mobile phone.
  • xOperator – combines advantages of social network websites with instant messaging
  • Semantic LDAP – Bringing together LDAP and the Semantic Web 
  • Triplify tackles the chicken-and-egg problem of the Semantic Web by providing a building block for the “semantification” of Web applications.
