Walk through of how the Provenance Access Scenario is satisfied using the Provenance Access and Query (W3C Editor's Draft 17 August 2011) proposal.

Online HTML Documents D1 and D2

  • Obtaining the document D
  • HTML documents D1 and D2 are accessed using HTTP GET, and the web servers return Link: headers as follows. We show examples using both the alternate proposals for anchor as a parameter and as a relation.

Using anchor parameter

GET https://github.com/timrdf/vsr/raw/master/data/source/tim-lebo/london-crime/version/2011-Jul-07/manual/crime.html HTTP/1.1
...

HTTP/1.1 200 OK
...
Link: http://example.com/provenance/d1.prov; rel="provenance"; anchor="https://github.com/timrdf/vsr/raw/master/data/source/tim-lebo/london-crime/version/2011-Jul-07/manual/crime.html"

GET http://lists.w3.org/Archives/Public/public-prov-wg/2011Jul/att-0031/crime.html HTTP/1.1
...

HTTP/1.1 200 OK
...
Link: http://example.com/provenance/d2.prov; rel="provenance"; anchor="http://lists.w3.org/Archives/Public/public-prov-wg/2011Jul/att-0031/crime.html"

Using anchor relation

GET https://github.com/timrdf/vsr/raw/master/data/source/tim-lebo/london-crime/version/2011-Jul-07/manual/crime.html HTTP/1.1
...

HTTP/1.1 200 OK
...
Link: http://example.com/provenance/d1.prov; rel="provenance"; 
Link: https://github.com/timrdf/vsr/raw/master/data/source/tim-lebo/london-crime/version/2011-Jul-07/manual/crime.html; rel="anchor" 

GET http://lists.w3.org/Archives/Public/public-prov-wg/2011Jul/att-0031/crime.html HTTP/1.1
...

HTTP/1.1 200 OK
...
Link: http://example.com/provenance/d2.prov; rel="provenance"; 
Link: http://lists.w3.org/Archives/Public/public-prov-wg/2011Jul/att-0031/crime.html; rel="anchor" 
  • Accessing the provenance
  • 'What information (I) does the clients (W) need in order to access and retrieve the provenance for the documents D1-2?
  • The browser uses the default mechanism for dereferencing the provenance-uris I_P for the two documents, which in our example is using a HTTP GET to retrieve the provenance document P.
  • The browser examines the provenance document P to locate the "section" that corresponds to the context-uri I_C that is relevant for the documents D1 and D2.
