1 shared innovation Licenses and Waivers in Practice Tom Heath Platform Division Talis Information Ltd ISWC2009 Tutorial on Legal and Social Frameworks for Sharing Data on the Web

2 Overview shared innovation Copyrightable Material Applying Creative Commons licenses Non-copyrightable Material Describing a Data Set with void Applying Waivers and Norms Special Cases: SPARQL Queries SELECT query responses DESCRIBE query responses CONSTRUCT query responses

3 Copyrightable Material shared innovation

4 1. Choose a CC License shared innovation

5 shared innovation 2. Add RDF Triples to Link Resource to rev: cc: < < rdf:type < ; rdfs:label Review of The Little Owl, Solihull, Birmingham ; rev:reviewer < ; rev:rating 3 ; rev:text Not bad for a pub next to the business park... ;... cc:license < sa/3.0/>.

6 shared innovation How the License looks in RDF < sa/3.0/> cc:permits cc:derivativeworks, cc:distribution, cc:reproduction ; cc:requires cc:attribution, cc:notice, cc:sharealike ; dc:creator < ; dc:title "Attribution Share Alike 3.0 Unported" ; xhv:alternate < sa/3.0/deed.af>,... < sa/3.0/rdf>.

7 Non-copyrightable Material shared innovation

8 Apply Waivers and Norms to Data Sets shared innovation void: Vocabulary of Interlinked Data Sets A vocabulary and a set of instructions that enables the discovery and usage of linked datasets A linked dataset is a collection of data, published and maintained by a single provider, available as RDF on the Web... A vocabulary for describing (aspects of) data sets

9 shared innovation Describe your Data Set with rdf: < rdf syntax foaf: dcterms: void: < < rdf:type void:dataset ; dcterms:title "Revyu Things" ; dcterms:description "All the Things in the Revyu dataset" ; foaf:homepage < ; void:exampleresource < little owl solihull birmingham>.

10 shared innovation Choose a Waiver (and Norms) for your Data Set ODC PDDL Waiver: Norms: CC0 Waiver:

11 shared innovation Add Waiver Statements to your void rdf: < rdf syntax foaf: dcterms: void: wv: < < rdf:type void:dataset ; dcterms:title "Revyu Things" ; dcterms:description "All the Things in the Revyu dataset" ;... wv:waiver < public domain dedicationand licence/> ; wv:norms < by sa/>.

12 shared innovation Tying it all rdf: < rdf syntax dcterms: void: cc: wv: < < rdf:type void:dataset ; dcterms:title Revyu Data ; void:subset < ; void:subset < < wv:waiver < public domai...> ; wv:norms < by sa/>. < cc:license < sa/3.0/>.

14 Special Cases: SPARQL Query Responses shared innovation

15 SELECT Query Responses shared innovation SPARQL Query Results XML Format <?xml version="1.0"?> <sparql xmlns=" results#"> <head> <variable name="thing"/> <variable name="review"/> <variable name="reviewer"/> <variable name="rating"/> <variable name="text"/> </head>... </sparql>

16 shared innovation SELECT Query Responses <?xml version="1.0"?> <sparql xmlns=" results#"> <head> <variable name="thing"/> <variable name="review"/> <variable name="reviewer"/> <variable name="rating"/> <variable name="text"/> <link href= /> </head>... </sparql> But what type of link is this? See:

17 shared innovation DESCRIBE Query rev: rdf: < rdf syntax dcterms: f: reviews < <> dcterms:ispartof < ; f:primarytopic reviews:8bd3f38371e06817e3011c72141cb < rdf:type rev:review ; rev:rating: "5" ; rev:reviewer: < ; rev:text....

18 DESCRIBE Query Responses shared rev: rdf: < rdf syntax dcterms: f: reviews < <> void:indataset? dcterms:ispartof < ; f:primarytopic reviews:8bd3f38371e06817e3011c72141cb < rdf:type rev:review ; rev:rating: "5" ; rev:reviewer: < ; rev:text....

19 CONSTRUCT Query Responses shared innovation?? Is it acceptable to inject additional triples the user has not requested? Who has rights to 'new' triples CONSTRUCTed by the query?
