▸ Data consistency
▹ PoolParty expects data to confirm to
▹ User can import arbitrary RDF data.
▸ Schema based constraints
▹ Data published without schemata or
with a minimally specified schema.
▹ Interpretation/usage of schemata
▸ Find a way to formulate constraints in a
easy maintainable way.
▸ Find a way to express constraints in a
unified way for usage throughout the

6 ▸ RDF Validation has been integrated.
▹ Checks are defined in RDF.
▹ Repair strategies and other
metadata are also defined as RDF.
▸ In a first step 15 checks have been
▸ Prototypes using RDF-Unit and SHACL
have been done.
10 ▸ Support validation of other RDF data and
▸ Support validation during data
▸ Support validation of data in different
places (built in store, remote store).
▸ Use a declarative approach (RDF Shapes)
▹ Integrate RDF-Unit
▹ Use SHACL
▹ Better to understand, maintain, reuse
