Consider an API query on ontologies

[bcorrie]

We currently have a set of ontologies in the specification (e.g. cell_subset).

A very powerful query mechanism for the API to implement would be to implement an ISA operator that would search for ontological containment of a concept, such as B cell. Such a search would return all repertoires that contained B cell or any of its children in the ontology.

For example:

{
  "filters": {
    "op":"isa",
    "content": {
      "field":"sample.cell_subset.id",
      "value":"CL:0000236"
    }
  }
}

would return anything that is under node CL:0000236 in the Cell Ontology.

This is a very difficult query to construct without this capability.

different from #234 ?

Nope, point taken... 8-) Great minds think alike, mine is just slower than yours... 8-)
