How to handle MeSH supplemental concepts that only map to an AllowedDescriptorQualifierPair

[dhimmel]

Some supplemental concept records (SCRs) in MeSH only have a preferredMappedTo whose predicate is a AllowedDescriptorQualifierPair rather than the usual TopicalDescriptor

For example, the SCR Disease Familial spinal arachnoiditis has preferredMappedTo to an AllowedDescriptorQualifierPair Arachnoiditis/congenital. So Arachnoiditis is the parent topical descriptor and congenital is the qualifier.

Currently, these edges are dropped:

Need to investigate whether any of these AllowedDescriptorQualifierPair parents would break our is-a / parent assumption. If they are consistent with a hierarchical conceptual relationship, then I'm thinking we just add an edge from Arachnoiditis to Familial spinal arachnoiditis with an edge property that for the congenital qualifier.

Here's how the implementation looks like in the exproted node-link formatted JSON.

First the node JSON (all normal here):

    {
      "mesh_id": "C531624",
      "mesh_class": "SCR_Disease",
      "mesh_uri": "http://id.nlm.nih.gov/mesh/2023/C531624",
      "mesh_label": "Familial spinal arachnoiditis",
      "mesh_date_created": "2010-08-25",
      "mesh_date_revised": "2016-07-19",
      "mesh_date_established": null,
      "mesh_frequency": 68.0,
      "mesh_description": "A hereditary form of arachnoiditis that may appear as a thick fibrous band on the spinal arachnoid membrane. It is characterized by adult onset SPASTIC PARAPARESIS with prominent radicular pain and patchy numbness. OMIM: 182950",
      "tree_numbers": null,
      "id": "C531624"
    },

Now the edge JSON:

    {
      "relationship_type": "preferredMappedTo",
      "parent_qualified_id": "D001100Q000151",
      "parent_qualifier_id": "Q000151",
      "source": "D001100",
      "target": "C531624"
    },

Note how parent_qualified_id is different than source, since source is based only on the parent descriptor ID (it strips out the qualifier id). You can access the qualifier in parent_qualifier_id.
