BSA — Metadata for properties necessary?

• We have many properties lying around the spec; do we need a mechanism for
  getting meta data on this? I think we must have discussed in some detail,
  but the situation is quite pressing for SearchHit in particular: there we
  have hit_info, where prolly the most important piece of information is the
  goodness of the hit. What's the name of that: "score"? "p-value"?
  "quality"? What's it's type: float? double ? long? I realize that this is
  difficult to answer (otherwise we would have included it), but we are open
  to suggestions to make the standard a bit more precise in this respect
  (e.g., we're still willing to host a public repository kind-a-thing).
