Query Reference Set - Examples Discussed

Example Instances - Option 1 (Linked on referencedComponentId/expansion set)

 Intensional definition reference set: 

ideffectiveTimeactivemoduleIdrefsetIdreferencedComponentId (expansionId)queryqueryLanguagequerySubstrate (is moduleId enough?)

3201801311M1R1 |My intensional ECL refset|Q3 |My third query|

 Expansion history reference set:

  1. Query spec reference set notes:

    1. Spec says "Simple type reference set", but QL will be able to generate much more in output
    2. Spec defines 900000000000513000 |Simple query specification|; maybe we should focus on a ECL-based version (which would exclude non-conceptids in results) since ECL is defined and QL is not?
    3. Note, QL requirements include lexical criteria but ECL does not.
    4. Refset members have meta-data properties like effectiveTime, moduleId; what should these be in for the intensional members?
    5. Which Version should the query be evaluated against?  
  2. I have included the reference set examples that we discussed today during the SLPG meeting (in the meeting agenda above). If there are further comments or thoughts on this, please let me know.
