Day 1: RDF, SPARQL and Discussion

• Brief look at RDF and SPARQL• Discussion– What constitutes data worth linking to?– How to find datasets suitable for interlinking? – How to make my dataset worth linking to?– How to encourage others to link to my data?– What is the added value of links? – How to determine the quality of a link?

Discussion: What constitutes data worth linking to?

• Size and coverage (e.g., DBPedia)

• Uniqueness - unique content attracts links (e.g., holdings in library setting)

• Completeness

Discussion: How to encourage others to link to my data?

• Make usage simple.• Provide data in

accessible formats.• Provide

downloadable data dumps

• Use open licence

Discussion: What is the added value of links?

• Enrich web sites with information curated elsewhere

• Provides multi-lingual content• Support resource discovery through authority

files, thesauri, synonym lists, etc.• Exploit additional structure imported from

Linked Data sources into our applications

Day 2: Tools

• Worked in Groups Looking at tools• SILK Framework– A Link Discovery Framework for the Web of Data– http://www4.wiwiss.fu-berlin.de/bizer/silk/

• LIMES - http://aksw.org/Projects/limes

• Prefix.cc - http://prefix.cc/

• 4store RDF triple store - http://www.4store.org/

Outcomes

• We learnt about RDF, SPARQL, Triples etc • Workshop documents clear and well prepared• Very useful pointers on SPARQL, triple store

tools, and interlinking datasets• Great to try SILK – should be useful for

subject, place and names interlinking across datasets

Outcomes • Workshop a little ‘uncomfortable’ for some

not already familiar with RDF, SPARQL • Steep learning curve, “very programmery”• Useful to have a separate SPARQL workshop• More time to work as a team• Jindřich was very helpful. Thanks!
