Linked Media Framework (European Data Forum 2012)

  1. 1. Thomas Kurz and Sergio Fernández Copenhagen, July 6-7, 2012 European Data Forum©
  2. 2. Linked Media Framework  An easy-to-setup server application that bundles central Semantic Web technologies: ● RDF store ● Linked Data server ● SPARQL 1.1 endpoint ● Semantic Search ● LDPath ● LDCache ● SKOS editor ● Reasoner ● Versioning ● etc...  Open Source, available at: http://lmf.googlecode.com©
  3. 3. LMF Architecture©
  4. 4. Linked Data server  RDF store  SPARQL 1.1 endpoint  Linked Data Explorer  Read-Write Web paradigm ● Authorization based on WebID and WebACL©
  5. 5. LMF Semantic Search  Facetted Search over content and metadata  SOLR compatible API  RDF Path Language (LDPath) for configurable metadata indexing ● Multiple Cores with different configurations to adapt to different search requirements©
  6. 6. LMF Reasoning  Rule-based reasoning triggered over triples in the LMF triple store to represent implicit knowledge  Reason maintenance allows to describe justifications for inferences  Adapted version of sKWRL rule language:  more efficient implementation  improved reason maintenance©
  7. 7. LMF Linked Data Caching  LDCache transparently retrieves linked resources from the Linked Data cloud when needed (e.g. LDPath or SPARQL query)  Powerful component for integrating with other information systems exposing their data as Linked Media or Linked Data  Adapters for services offering their data in proprietary formats (e.g. YouTube, Vimeo, …)©
  8. 8. LMF Versioning  Keeps track of any resource updates in the triple store  Providing information about trust and provenance of data, e.g. annotations added to the system  Transaction-based versioning  Implementation of the Memento protocol©
  9. 9. LMF Client Libraries  Bindings for the LMF API  A convenient option to use LMF for Linked Data development  Available for different languages ● Java ● PHP ● Javascript©
