Hello,
I'm interested to know if there is a way to configure the apache jena
shacl cli tool to output the values of sh:message or sh:resultMessage. I
have a property shape where I tried adding contextual info into
sh:message/sh:resultMessage. I would like to see this info in the output
from the shacl cli in the case of failed validation. Here is an minimal
example to show the situation, in case I'm just doing something wrong.
schema.ttl:
@prefix schema: <http://schema.org/> .
@prefix sh: <http://www.w3.org/ns/shacl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix regen: <http://regen.network/> .
regen:ProjectPageShape a sh:NodeShape ;
sh:targetClass regen:Project-Page ;
sh:or (
[ sh:not
[ sh:path regen:landStewardStory ;
sh:minCount 1 ;
sh:maxCount 1
]
]
[
sh:and (
[ sh:path regen:landStewardStory ;
sh:minCount 1 ;
sh:maxCount 1 ;
sh:minLength 1 ;
sh:maxLength 500 ;
sh:datatype xsd:string
]
[
sh:path regen:landStewardStoryTitle ;
sh:resultMessage "regen:landStewardStoryTitle missing" ;
sh:minCount 1 ;
sh:maxCount 1 ;
sh:minLength 1 ;
sh:maxLength 160 ;
sh:datatype xsd:string
]
)
]
);
.
data.jsonld:
{
"@context": {
"regen": "http://regen.network/";,
Syntax error in the JSON.
},
"@type": "regen:Project-Page",
"regen:landStewardStory": "In 1998, the local community supported
our plan to establish the Rukinga Wildlife Sanctuary that covers
80,000 acres of forest. We established a community works project so
local residents had an alternative income stream in place of poaching
and clear cutting. We brought on locally hired rangers and trained
them to be wilderness guardians. We convinced the owners of the cattle
to remove the cattle from the land to reduce conflict over resources."
}
And here is the output from running "shacl validate --text
--shapes=schema.ttl --data=data.jsonld":
[ rdf:type sh:ValidationReport ;
sh:conforms false ;
sh:result [ rdf:type sh:ValidationResult ;
sh:focusNode _:b0 ;
sh:resultMessage "Or at focusNode
_:Bccda076ea2a1aedde6ef53f415f1b148" ;
sh:resultSeverity sh:Violation ;
sh:sourceConstraintComponent sh:OrConstraintComponent ;
sh:sourceShape regen:ProjectPageShape ;
sh:value _:b0
]
] .
The result I am looking for would look like this:
[ rdf:type sh:ValidationReport ;
sh:conforms false ;
sh:result [ rdf:type sh:ValidationResult ;
sh:focusNode _:b0 ;
sh:resultMessage "regen:landStewardStoryTitle missing" ;
sh:resultSeverity sh:Violation ;
sh:sourceConstraintComponent sh:OrConstraintComponent ;
sh:sourceShape regen:ProjectPageShape ;
sh:value _:b0
]
] .
Any suggestions on how this could be achieved?
The constraint failing is the sh:or which doesn't have a resultMessage.
Rereading the SHACL spec, there isn't any text about rolling up messages
- what do other engines do?
There is the Zazuko SAHCL playground
https://shacl-playground.zazuko.com/
it find s the violation but it does not print a message.
Some of the SHACL user community are to be found on Discord:
https://discord.gg/RTbGfJqdKB
where you might get suggestions.
