Hi Oleksandr,
the specific constraints from your screenshot originate from the file
TopBraid/SPIN/spinowl.ttl. That file is usually not owl:imported so I am
wondering how it ended up in your EVN vocabularies. If you can track
that back, there would be an owl:imports or spin:imports triple pointing
at the file, which you can remove (see below). It is possible that the
checking of these constraints has become slower in 5.3 because we had to
make adjustments to the way that SPIN loops through the values of ?this
due to changes in the variable scoping of the underlying SPARQL engine.
FWIW I am also working on redoing (and actually extending) the default
teamwork constraints (from http://topbraid.org/teamworkconstraints) that
are imported by default into every new EVN/EDG vocabulary. In 5.3 and
older versions there are two SPIN-based constraints that interpret
owl:FunctionalProperties and owl:maxCardinality restrictions with closed
world semantics, implemented in SPIN. I believe I will simply remove
those for 5.4 because people should use SHACL sh:maxCount to express
such things. Likewise the constraints from spinowl look outdated now
that SHACL is around the corner. Once everything is in SHACL, users will
be able to disable any constraint using sh:deactivated in 5.4.
Meanwhile, for users who don't want those tests, your best bet to get
rid of them is to remove the triple <urn:x-evn-master:XY>
owl:imports|spin:imports <http://topbraid.org/teamworkconstraints>.
There is no way to do that from the UI right now for the default
"system" includes, so I am afraid you may need to run a SPARQL update
with a DELETE via the SPARQL endpoint as a quick fix.
Thanks
Holger

Hello,
recently I found that generating constraint violations report takes
much more time than previously (probably after updating to EVN 5.3).
After investigation I found that owl:Thing has a set of constraints
which are checking during generating violations report.
Is it possible to disable these constraints? And if yes, how can I do it?

Thanks.
