I have done a little testing at V2 to model a parent children hierarchy that we
would need to define a Glossary (see Jira 1410)
I define types EntityA with a children 1 to many optional attribute to EntityB.
EntityB has a mantidory pointer to an EntityA parent.
EntityA type has
"name": "children",
"typeName": "array<EntityB>",
"cardinality": "SINGLE",
"constraintDefs": [
{
"type": "ownedRef"
}
],
],
"isIndexable": false,
"isOptional": true,
"isUnique": false
},
EntityB type has attributes like this:
"name": "parent",
"typeName": "EntityA",
"cardinality": "SINGLE",
"constraintDefs": [
{
"type": "inverseRef",
"params": {
"attribute": "children"
}
}
],
"isIndexable": false,
"isOptional": false,
"isUnique": false
I then define
-an instance of EntityA
-an instance of EntityB with parent pointing to EntityA (I have to supply the
parent attribute as it is isOptional false).
If I then get (using the API) the EntityA instance it does not have any content
in its children. Is this expected? It seems that if I am allowed to do this
then the children and parent pointers are out of sync.
Am I missing something?
