What we have understood

Freshness above is about the data being current. This is about the data being understood: how many of the catalogue's fields carry a meaning we can act on, which datasets are still waiting, and how far the joinable web reaches.

The web of datasets and fields

A line means a dataset carries a field tagged with a shared vocabulary term. Two datasets on the same term speak the same language about it, which is what makes a cross-dataset question possible. Sharing a term is not the same as a working join — the dataset page says whether a specific pair compiles.

Bipartite. A dimension node is a conformed-dimension family; a dataset node is a catalog dataset; an edge means that dataset carries at least one column tagged with that dimension, and names the columns that carry it.

No field list yet: We hold no columns for these at all.
Nothing read yet: We hold their columns and have decided none of them.
Under half read: Fewer than half their fields carry a verdict.
Half read: At least half their fields carry a verdict.
Most read: At least three quarters of their fields carry a verdict.
Every field decided: Every field carries a verdict — which does not mean every field is understood.

How many of an edge's tagging columns carry a method that actually read something. Zero means the edge rests entirely on carried lexical tags.

Two datasets on the same dimension node share a vocabulary, which is weaker than a join. GET /api/datasets/{fourFour}/bindings/{partner} decides whether a specific pair compiles; executing it additionally needs both marts present.
