      description: >-
        The Query class is used to package a user request for information. A
        Query object consists of a required Message object with optional
        additional properties. Additional properties are intended to convey
        implementation-specific or query-independent parameters. For example,
        an additional property specifying a log level could allow a user to
        override the default log level in order to receive more fine-grained
        log information when debugging an issue.

            The server MAY POST `Response` objects before work is fully

            If appropriate, it SHOULD be the term name of the CURIE used

            Relationship between the database value and the constraint value

            is equal to, is greater than, and is less than,
            respectively. The 'matches' operator indicates that the value
            is a regular expression to be evaluated. If value is a list type,
            then at least one evaluation must be true (equivalent to OR).
            This means that the == operator with a list acts like a SQL 'IN'
            clause. If the value of the compared attribute is a list, then
            comparisons are performed between each of the constraint values
            and each of the attribute values, and any one true evaluation
            counts as an overall true (e.g., [1,2,3] == [6,7,2] is true).
            The == operator is therefore a broad interpretation of inclusion.
            The '===' operator requires that the constraint value and
            the attribute value be the same data type, length,
            content, and order (e.g. only [1,2,3] === [1,2,3]).
            The 'not' property negates the operator such that not
            and == means 'not equal to' (or 'not in' for a list), and not >
            means <=, and not < means >=, not matches means does not
            match, and not === means the match between the constraint
            and attribute values are not exact.
            The '==' operator SHOULD NOT be used in a manner that
            describes an "is a" subclass relationship for the parent QNode.

            - ==

            If the value is a list and there are multiple items, at least one
            comparison must be true (equivalent to OR) unless the '==='
            operator is used. If 'value' is of data
            type 'object', the keys of the object MAY be treated as a list.
            A 'list' data type paired with the '>' or '<' operators will

            An upstream InformationResource from which the resource
            being described directly retrieved a record of the knowledge
            expressed in the Edge, or data used to generate this knowledge.
            This is an array because there are cases where a merged Edge
            holds knowledge that was retrieved from multiple sources. e.g.
            an Edge provided by the ARAGORN ARA can expressing knowledge it
            retrieved from both the automat-mychem-info and molepro KPs,
            which both provided it with records of this single fact.
          example: [infores:automat-mychem-info, infores:molepro]

            A URL linking to a specific web page or document provided by the 
            source, that contains a record of the knowledge expressed in the 
            Edge. If the knowledge is contained in more than one web page on 
            an Information Resource's site, urls MAY be provided for each. 
            For example, Therapeutic Targets Database (TTD) has separate web 
            pages for 'Imatinib' and its protein target KIT, both of which hold 
            the claim that 'the KIT protein is a therapeutic target for Imatinib'.

      description: >-
        The role played by the InformationResource in serving as a
        source for an Edge. Note that a given Edge should have one
        and only one 'primary' source, and may have any number of
        'aggregator' or 'supporting data' sources.  This enumeration
        is found in Biolink Model, but is repeated here for convenience.
      enum:
        - primary_knowledge_source
        - aggregator_knowledge_source
        - supporting_data_source
