Report of Linked Data Camp Vienna
Earlier this month the first ever Linked Data Camp took place in Vienna at the Quartier für Digitale Kunst. This two day event attracted about 35 people to discuss and to jointly work on novel applications for the Web of Data.
The first day started off with a keynote by Richard Cyganiak form DERI Galway’s Linked Data Research Center. He talked about the technical challenges that have to be overcome to allow for more Linked Data applications over heterogenous RDF data. These challenges revolve around discovery of and access to Linked Data, identifier and schema reconciliation, data fusion, quality assessment, aggregation, analytics and mining.
As Richard pointed out, the good news is “that linked data makes it possible that different people do the different steps, e.g., the publisher can help doing the identifier reconciliation by publishing sameAs links, and 3rd parties can help with access by providing a single SPARQL store over multiple related but independent datasets.” Check out the transcript
or slides for Richard’s talk.
After this keynote participants presented their topics of interest in Lightning Talks and working groups formed, some of their outcomes can be found online:
One group worked on the topic of “Dataset Dynamics”. As data in Linked Data sets change, clients having some dependency on data need to be notified about these changes. You can read about their proposed solutions here.
Another group had a go at “Expert search and profiling on the Semantic Web”, their discussions are summarized in this blog post.
Andreas Langegger demonstrated XLWrap, which is a versatile RDF wrapper for spreadsheets. A lot of feature request from participants came up (see here), so he and others worked on this handy application.
On day 2 Leigh Dodds from Talis talked about “Rights Statements on the Web of Data” (slides and transcript). Leigh raised awareness for the issue that the majority of LOD sources do not have licensing information associated with their data. This of course conflicts with the proposed openness of Linked “Open” Data, as it is doubtful whether these sources can be used for commercial puropses.
The organizers from the universities of Linz and Vienna, Joanneum Research, Gnowsis, DERI Galway, STI Innsbruck and the Semantic Web Company would like to thank all participants for making the camp a success! As with VoCamps anyone can organize a Linked Data Camp, so we hope for more camps in 2010!
