Class: EdgeType

name: EdgeType
description: 'A structure for describing each type of edge (metaedge) created in the
  target knowledge graph by this ingest, including what types of edge properties it
  holds, and a brief explanation of why this modeling pattern was deemed appropriate
  to represent the source data (for display to end users in a UI system). Note that
  an edge type with multiple subject_category and object_category values does not
  mean that the full cross-product must be instantiated in the data. e.g. A KG with
  the edge type sub_cat: [Gene, Protein, Small Molecule], predicate: affects, obj_cat:
  [disease, phenotype, symptom] might include  Protein-affects-Disease and Gene-affects-Symptom
  edges, but not include any  Protein-affects-Symptom edges.'

  subject_categories:
    name: subject_categories
    description: The Biolink category of the subject node of this edge type. e.g.
      "biolink:SmallMolecule". If two edge types differ only in their subject category,
      but use the same predicate, object_category,  edge properties, and general provenance,
      they can be described together in a single NodeType object that captures the
      alternative subject categories. e.g. if a source provides SmallMolecule-treats-Disease
      and  MolecularMixture-treats-Disease edge types, these can be described in a
      single EdgeType object with two subject categories (SmallMolecule and MolecularMixture).

      e.g. if a source provides Gene-associated_with-Disease and  Gene-associated_with-PhenotypicFeature
      edge types, these can be described in a single EdgeType object with two subject
      categories (Disease and PhenotypicFeature)
