Andy Seaborne commented on JENA-1499:
-------------------------------------
Could you explain a bit about what {{QuadTableForm.GSPO.listGraphNodes}} is
doing? I haven't looked at these details of `QuadTableForm` before. Can empty
graphs appear in other ways? Does traversal of {{G\?\?\?}} simply on generate
quads if the subtree is partial (i.e. empty) some how in {{GS\?\?}} ?
> The TIM dataset retains a memory of named graphs after deleting all quads.
