Understand the data
What connections mean, where they come from, and how catalog coverage is measured.
A connection records how two entries relate. Its label might say that a person created a work, a building is located in a place, or an idea influenced another idea.
Connections help you move through the catalog. Their explanations and available citations help you understand why the link was recorded.
Connections use specific labels such as created, influenced by, derived from, located in, member of, and participated in. Each belongs to one of the six broad families described in Core concepts.
Directional labels change when read from the other end: a work is created by a person; the person created the work. Symmetric connections, such as similarity, apply in both directions.
Causal connections also carry a positive or negative sign describing the recorded effect. A sign does not establish the strength or certainty of that claim.
The Wikidata lookup uses a fixed mapping from supported properties to connection labels. It does not infer arbitrary connections from an AI model. Unsupported properties are skipped and reported.
Some connection batches are stored as Proposed and accepted after review. Connections requiring individual judgment can go through the suggestions queue. Imports approved through their preview process can write accepted records directly. See How entries are added for how review status works.
The current workflow requires citations for machine-written connections. Older records may still have citation gaps. Follow the visible source badge where available; a recorded connection is not automatically a verified fact.
The project measures how much of the accepted catalog is connected. A connected group (or web) is a set of entries reachable through recorded links when measuring connectivity, regardless of the direction of a particular relationship. An island is an entry with no recorded connection.
| Measure | What it means | Target |
|---|---|---|
| Largest connected group | Share of accepted entries in the largest group. | At least 90%. |
| Unexplained islands | Entries without connections and without a recorded unsuccessful search for one. | Zero. |
| Connections per entry | Accepted connection records divided by accepted entries. This is not average graph degree. | At least 1.5. |
| Cited machine-written connections | Share of machine-written connections with a citation. | 100%. |
These are project targets, not claims that the demo currently meets them. They measure coverage, not the truth or usefulness of every connection.
The catalog is incomplete. Two related subjects may not yet have a recorded path between them. Some fields have much better coverage than others.
The Network shows what has been recorded. It does not prove that unconnected subjects are unrelated, and it does not create a new relationship just because two points appear close together.
