  There are many case studies for which the formulation of RDF constraints and
the validation of RDF data conforming to these constraint is very important. As
a part of the collaboration with the W3C and the DCMI working groups on RDF
validation, we identified major RDF validation requirements and initiated an
RDF validation requirements database which is available to contribute at
http://purl.org/net/rdf-validation. The purpose of this database is to
collaboratively collect case studies, use cases, requirements, and solutions
regarding RDF validation. Although, there are multiple constraint languages
which can be used to formulate RDF constraints (associated with these
requirements), there is no standard way to formulate them. This paper serves to
evaluate to which extend each requirement is satisfied by each of these
constraint languages. We take reasoning into account as an important
pre-validation step and therefore map constraints to DL in order to show that
each constraint can be mapped to an ontology describing RDF constraints
generically.
