Short Bio

I have been working at the North Rhine-Westphalian Library Service Center (hbz) and promoting open knowledge since 2008. I am primarily working on hbz's linked open data service lobid (launched in 2010) focusing on project management, metadata modeling and vocabularies. Other areas of work are Open Educational Resources (OER). I am co-chair of the programme committee for the annual international conference Semantic Web in Libraries (SWIB).

Interest in LODLAM

I attended the first LODLAM summit in San Francisco in 2011 and I really liked the atmosphere of getting things done. My main areas of work are metadata modeling and vocabularies. I would be happy to share my experience and to see what others are up to. One concrete topic that would interest me is discussing an annotation-based approach of documenting data models, APIs etc.

Also, I am interested in further connecting the SWIB and LODLAM communities.

Linked Open Data Projects

Our linked open data service lobid ( makes three different data sets that are aggregated from different sources available via a linked (open) data API:

– lobid-resources publishes the hbz union catalog as linked open data
– subject service provides access to the Integrated Authority File (GND)
– lobid-organisations ( is a comprehensive index of libraries, archives and museums in German-speaking countries.

Currently, we are in the last part of a longer process of moving the APIs to a new version with improved access possibilities as well as building new user interfaces on top. Technology-wise, we heavily rely on ElasticSearch as search index which we feed with JSON-LD that is created from the source data using the ETL software Metafacture.

I am also part of the OER World Map ( team. The OER World Map collects information on people, organizations, services, projects and events related to OER. Itaims at accelerating the evolution of the global OER system by strengthening the ability of the OER community to organize itself.
