Complementarity Use Cases

"viewOf" as the fundemental underpinning relation (GK)

For me, the relationship I call "viewOf, where "A viewOf B" means that A is a constrained view or version of B (e.g. "Luc in Boston" is a constrained view of "Luc"), is the fundamental underpinning on which other kinds of complementarity may be built.

As a notion, "viewOf" is quite easy to understand (if not describe), and is the basic idea which explains relationships between Resources/Entities which allows us to make provenance statements with enduring truth, hence tractability for analysis.

Use-case:

"Weather in London on Thursday" is a view of "Weather in London", where we might assign specific provenance to the former but not necessarily the latter.

"viewOf" as an orthogonal dimension of derivation

:luc_in_boston
   a prov:Entity;
   prov:viewOf <http://data.semanticweb.org/person/luc-moreau>;
   foaf:based_near <http://dbpedia.org/resource/Boston>;
.

:flight_home
   a prov:Activity;
   foaf:based_near <http://dbpedia.org/resource/Atlantic_Ocean>;
   prov:used      :luc_in_boston;
   prov:generated :luc_in_southhampton;
.

:luc_in_southhampton
   a prov:Entity;
   prov:viewOf <http://data.semanticweb.org/person/luc-moreau>;
   foaf:based_near <http://dbpedia.org/resource/Southhampton>;
.

Question (GK): what is "viewOf" here orthogonal to?
