Hi Holger,
Things are looking good on my end using TBC 7.0.1 and only importing the SHACL 
URI and not dash or tosh. Running SHACL reasoning and SHACL validation both 
seem to work reliably. I'm assuming that, as you mentioned, dash and/or tosh 
are brought in automatically if needed.

The only exception is a summer student working on the standards project who is 
using the TBC Free edition (which seems to have moved backwards to 6.0.1). It 
seems to choke when validating because it isn't finding some tosh objects.
(Caused by: java.lang.IllegalArgumentException: Shapes graph does not include 
tosh:http://datashapes.org/dash#DefaultValueTypeRule)

The workaround for the student is just to have him explicitly import dash.ttl 
whenever he wants to run the validator, but remove it before doing his git 
push. I know that you all aren't supporting TBC Free any more, but I just 
wanted to confirm that this is expected behavior.

Yes this sounds plausible. The SHACL engine in that version was different.

In addition to the extra constraint components

    http://datashapes.org/constraints.html

the dash namespace also imports the tosh namespace, which contains constraints 
on the SHACL metamodel and therefore is used to drive the forms in EDG.

What you do with the files generated with TopBraid outside of TopBraid is of 
course your own decision. I assume all standards-compliant SHACL validation 
engines will support at least SHACL Core without any mandatory owl:imports. In 
the SHACL API that I wrote, the code uses dash and tosh internally to identify 
the constraint components, so they are internally added in case they don't 
exist in the provided shapes graph. But this happens automatically.

Very cool! With bated breath, I tried it, and nothing blew up!

It would be good to know at some point what functionality I lose by directly 
importing
owl:imports <http://www.w3.org/ns/shacl#<http://www.w3.org/ns/shacl>> ;
instead of
  owl:imports <http://datashapes.org/dash> ;

Hi Steve and Michel

I’m not near my computer so cannot do it for you, but suggest replacing dash 
import with SHACL import and trying it. I think that’s ok.
Cheers,

Onderwerp: [topbraid-users] Staying with official SHACL

Hi, I'm working with a standards committee that would rather avoid straying 
outside the official W3C SHACL standard. My question is, if I removed the 
import of datashapes.org/dash<http://datashapes.org/dash> from the files I'm 
working with, does this bring the TopQuadrant tools to a crashing halt as far 
as running the SHACL reasoner?

I suppose another way of asking this is whether SHACL is built in to TBC under 
the hood, or is the dash import part of that?
