56,681 columns in the coverage ledger · read from /api/field-coverage on citytap-prod · source last observed Oct 10, 2026, 10:53 AM
3,026 datasets, 56,681 catalogued fields, 36,243 of them still unread. Every band below is a share of that, worst first. Open one to see its datasets.
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.

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.
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.
