tpluscode has just created a new issue for https://github.com/w3c/data-shapes:
== Feature: `sh:deepEquals` and `sh:deepHasValue` ==
I'm just now looking at a use case where I want to ensure immutability of a property alongside possible subgraph triples.
```turtle
<foo>
a ex:Foo ;
ex:child [
rdfs:label "bar" ;
ex:child [
rdfs:label "baz" ;
] ;
] ;
.
```
A Property Shape like below could be used to ensure that no property of `ex:child` and its descendants changes
```turtle
[
sh:path ex:child;
sh:deepHasValue [
rdfs:label "bar" ;
ex:child [
rdfs:label "baz" ;
] ;
] ;
]
```
The underlying use case is a HTTP request where I want to ensure immutability of a property and its subgraph. So my shape triples would be only include `dash:readOnly` ...
```turtle
<>
a sh:NodeShape ;
sh:targetClass <FileData> ;
sh:property [
sh:path schema:encoding ;
dash:readOnly true ;
] ;
.
```
... and I can dynamically generate `sh:deepHasValue` from the persisted resource state.
