DB USING [Entity, Segment],

Rope USING [ROPE];

BEGIN OPEN Rope, DB;

EntityToName: PROC[e: Entity, seg: Segment] RETURNS[name: ROPE];

Includes in the name the file corresponding to the database segment, so that the name produced uniquely indetifiers the entity (no confusion about which Walnut segment it might reside in, for instance)

MakeName: PROC[seg: DB.Segment, domain, eName: ROPE] RETURNS[name: ROPE];

MakeName is useful when the entity might not exist yet

NameToEntity: PROC[name: ROPE, create: BOOL ← FALSE] RETURNS[e: Entity];

May return NIL if name cannot be mapped onto any open segment

SegmentOf: PROC[name: ROPE] RETURNS[segment: Segment, filePath: ROPE];

DecomposeName: PROC[name: ROPE] RETURNS[segment, domain, entity: ROPE]

END. . .
