How to produce LinkedData ?•  Support still emerging in existing platforms•  Commercial tools are available•  Many more academic or experimental tools Photo -‐ shu@erhacks, “Books” August 27, 2008 via Flickr, CreaNve Commons A@ribuNon.

Augment existing HTMLpages•  RDFa •  Lightweight annotaNons •  Adopted by •  Content Management Systems (e.g. Drupal 7) •  Search engines •  Google Rich Snippets •  Yahoo SearchMonkey Photo -‐ Hans Põldoja, “Tag cloud” November, 12 2009 via Flickr, CreaNve Commons A@ribuNon.

Map Databases•  D2RQ •  Non-‐RDF databases mapped as virtual RDF graph •  R2RML •  W3C’s RDB to RDF Mapping language •  Triplify •  Database queries/views mapped to RDF Photo – Nate Grigg, “IndicaNng” March 19, 2009 via Flickr, CreaNve Commons A@ribuNon.

Linked Data using Semantic MediaWiki•  Extension(s) to MediaWiki•  Used by large BioWikis •  SNPedia, NeuroLex •  Looks like a wiki - Acts as Linked Data •  SemanNc annotaNons •  Tags with meaning

Many data integration optionsMediaWiki extensions •  Page attribution, social media, authenticationSemantic extensions •  Forms, drill-down, data integration, result formats, RDFa, triple store connectors

Standardize annotations with forms

Collaboration, Knowledge Managementtools

Seamless semantic layer

Triple store synchronization

Application to Translational Research•  Collaborative data sourcecatalog •  Origin and nature of content •  How to access it •  How it is licensed •  Relationships to other data sources•  Enables easier queriesfrom a single tool •  Both internal and external data sources

Semantic Data Integration Contributors add or edit wiki pages Enterprise Search Data browser and visualizaNon Seman&c MediaWiki Triple Store Editors create queries Queries into metadata catalog Import content from remote sources Ontology CuraNon

Consumed by analytics app, visualization,search engine

What next ?•  Semantic MediaWiki can also consume Linked Data •  MediaWiki extensions : LinkedWiki, RDFIO, SMW+ •  Standalone project : ShorNpedia •  Upcoming version will use RDF triples as primary storagePhoto – Reed Sturtevant, “Linked Data candies” January 15, 2010 via Flickr, CreaNve Commons A@ribuNon.
