Create or get hierarchy of terms key issue

[tmsincomb]

Issue

If the entity is not found and will be created, the following issues can be found

1. upstream entity is already created, but not found and attempt of creation of upstream entity failed
2. upstream entity found and was not properly ignored if already created with the transaction

If the entity is found and will not be created, the following issues can be found
3. back populating object to return failed

Solution

• Issues 1-3 can be partly solved by creating strict prerequisites of fields to query the hierarchy of a term to be created.
• Caching core fields for aspects and objects of entities will most likely remedy the rest since expecting all constrained fields to be known might not be efficient.
