PROV Show

Strategies

When RDF data is upload to PROV Show, a selected strategy is applied to it before visualisation which either removes or adds RDF data to/from the graph to allow for certain types of visualisation. For example, the basic strategy adds wasGeneratedBy relationship whenever it encounters generated relationships (i.e. A generated B becomes B wasGeneratedBy A with the two properties being defined as inverse in PROV-O) so that all arrows in a visualised node network graph point backwards in time.

Where objects do not have an rdfs:label property, a label is made from it's URI. This applied to blank nodes too.

The actual code used for each strategy is available in GitHub repository.

The following strategies are currently implemented with more on the way:

Basic

This basic strategy is the default. It aims to represent simple Entity, Activity & Agent classes of object with basic relationships only. It performs the following actions on uploaded data:

Entities only

This strategy removes everything from uploaded RDF data other than Entities and builds relationships between Entities where it can reason about them from other relationships. Specifically it will:
