QUESTION
I am learning ShEx and using 'shexjava API' done by http://shexjava.lille.inria.fr/ for my project. I have schema, data graph and fixed shape map. When I validate using refine and recursive validation, I am getting ResultShapeMap but the reason and appInfo are null for NONCONFORMANT status. I do not understand why these two fields are null.
I have schema, dataGraph, shapeMap. This is code for validation.
...ANSWER
Answered 2020-Apr-24 at 09:38The shexjava implementation currently does not support indicating a reason for failure. This is because when a node does not satisfy a shape there may be several reasons.
If you want to learn ShEx, I would advise you to use ShapeDesigner
https://gitlab.inria.fr/jdusart/shexjapp/
which provides a graphical interface in which you can explore validation results.
In this particular case, it indicates that the validation fails because 23 is not a decimal (it's actually an integer) Screenshot of validation exploration result in ShapeDesigner
I do not know whether this is a bug, i.e. whether integrers should be considered to be also decimals in RDF.
QUESTION
I have a repo with ~70 test of executables. When running under mocha or jest, it typically gets either errors on the first couple promises, either because of a timeout or because stdout never made it back to the parent process.
My minimal replication of this problem involves 100 threads, each calling a command line which sleeps for 10s:

Answered 2017-Oct-22 at 21:50The error message from the demo that you linked to actually describes the exact problem.
Error validating http://www.epri.com/studies/3002011786studyVariable as {"type":"NodeConstraint","datatype":"http://www.epri.com/studies/3002011786studyVariable"}: mismatched datatype: http://www.epri.com/studies/3002011786studyVariable is not a literal with datatype http://www.epri.com/studies/3002011786studyVariable
You're using a datatype constraint, which isn't what you want.
You need to use a [ st:studyVariable ]
, instead, since you want to specify a value set:
