Entity resolution includes document license
Mon, 07 Mar 2016

Today we added information about the document resource (include licensing) in the data obtained when resolving Linked Data URIs.

What does it mean? For example, resolving URI "" (with header Accept: application/rdf+xml) the client is redirected to "", to obtain what follows:

   <j.3:Document rdf:about="">
     <j.0:license rdf:resource=""/>
       <j.1:Offering rdf:about="">
         <j.1:availableAtOrFrom rdf:resource=""/>
         <j.2:validForPresentation rdf:resource=""/>
         <j.4:inDataset rdf:resource=""/>
         <j.1:availabilityEnds rdf:datatype=""
         <j.1:hasPriceSpecification rdf:resource=""/>
         <j.1:includes rdf:resource=""/>
         <rdfs:label>Offer for course KG002: &amp;pound;185.00 in GR for presentation 2016C</rdfs:label>

Note: the URIs representing resources (and not entities) are not represented in the data store, so you cannot find them by querying the SPARQL endpoint. In our example, there is not triple

 <> a foaf:Document

but of course you'll find everything about "", as usual.

Youtube videos now related to OU courses and qualifications
Thu, 12 Dec 2013

The context is where we collect data about the presence of the Open University on YouTube. We now extract content from all OU channels. Videos and Playlists are now linked to courses and qualifications.

Try the following query, to see OU content related to a YouTube video using the YouTube video id (from the URL, eg, just take "SYry6PYsL8o"):

  prefix rdf: <>
  prefix podcast: <>
  prefix yt: <>
  prefix rdfs: <>
  prefix rkb: <>
  prefix saou: <>
  prefix dbp: <>
  prefix media: <>
  prefix olearn: <>
  prefix mlo: <>
  prefix bazaar: <>
  prefix schema: <>

  (?related as ?identifier)
  (str(?location) as ?link)

  FROM <>
  FROM <>
  FROM <>
  FROM <>
  FROM <>
 ?x schema:productID "SYry6PYsL8o" . # change the youtube id to any OU youtube video
 ?x  yt:relatesToCourse ?course .
       # related video podcasts
           ?related podcast:relatesToCourse ?course .
           ?related a podcast:VideoPodcast .
       ?related rdfs:label ?label .
           optional { ?related bazaar:download ?location }
       BIND( "VideoPodcast" as ?type ) .
     } union {
       # related audio podcasts
           ?related podcast:relatesToCourse ?course . 
           ?related a podcast:AudioPodcast .
       ?related rdfs:label ?label .
           optional { ?related bazaar:download ?location }
       BIND( "AudioPodcast" as ?type ) .
     } union {
       # related openlearn units
           ?related a olearn:OpenLearnUnit .
       ?related olearn:relatesToCourse ?course  .
       BIND( "OpenLearnUnit" as ?type ) .
           ?related <> ?location .
       ?related rdfs:label ?label .
     } union {
           # related qualifications (compulsory course)
           ?related a mlo:qualification .
           ?related saou:hasPathway/saou:hasStage/saou:includesCompulsoryCourse ?course  .
       BIND( "Qualification" as ?type ) .
       ?related rdfs:label ?label .
       ?related mlo:url ?location 

Or can grab a YouTube code directly from the data:

  prefix yt: <>
  PREFIX dct: <>
  prefix schema: <>


  FROM <>

    ?x schema:productID ?code ;
           dct:published ?published ;
           yt:relatesToCourse []

  } order by desc (?published)

   FROM <>
   WHERE {
    [] ?property ?value ;
       aiiso:code ?code;
       a cw:Course .
