Create function

[MSV]

Hi,
I want to create a function and use it in sparql.
Function would take an id and verify a geaph nd return a boolean.
How can i do this?

Hi,

the syntax of SPARQL functions defined using SHACL is described at

https://w3c.github.io/shacl/shacl-af/#functions-example

I am not sure what you mean with "verify a graph", but I guess you could
try to formulate that condition in the sh:select, or (in your case of
boolean results) using sh:ask?
