Features and Limitations

The current implementation of Trav-SHACL does not cover all features of the complete SHACL language. The following is a list of what is supported:

simple cardinality constraints, i.e., sh:minCount and sh:maxCount
relaxed shape-based constraints, i.e., sh:qualifiedValueShape with sh:qualifiedMinCount and sh:qualifiedMaxCount
simple SPARQL constraints, i.e., sh:sparql with sh:select
- sh:prefixes is currently not implemented, i.e., the query needs to use full URIs or specify the prefixes within sh:select
- sh:message is ignored, i.e., the message is not included in the result
- only $this is supported as placeholder
simple logical constraints, i.e., sh:or
Trav-SHACL is capable of validating
- public SPARQL endpoints
- private SPARQL endpoints via HTTP Basic Auth (since v1.6.0)
- RDFLib graphs (since v1.3.0)

The following is a list of some of the more important features that are not yet covered:
