Module members 

Reference set memberships: for every reference set of an edition, the bitmap of the concepts that are its active members.

?fhir_vs=refset/[sctid] and the concept in [sctid] filter of the FHIR SNOMED CT page read one bitmap; ?fhir_vs=refset reads the keys. No spec governs the layout: our own design. Little-endian, a magic and version prefix, a count, then per reference set its SCTID as u64, the bitmap’s serialized length, and the bitmap in roaring’s portable serialization.
