How to Use the Wikidata Fact Box
The Wikidata fact box appears beside the Wikipedia panel whenever you click an entity in the 3D knowledge graph. Where Wikipedia shows you prose, Wikidata shows you a scannable card: image, label, curated key-value facts, authority links, and a deep link back to the canonical record. This guide covers the panel’s states, the disambiguation flow, and the offline behavior.
Prerequisites
Section titled “Prerequisites”- A vault with a built knowledge graph
- Internet access on the first lookup for each entity (subsequent clicks are cached)
- No setup needed — the fact box ships enabled by default
Open the fact box
Section titled “Open the fact box”Click any node in the 3D knowledge graph view. Two panels appear in the top-left corner of the canvas:
- Wikipedia (violet icon) — a list of matching articles
- Wikidata (amber icon) — the fact box for the most likely QID
The panels load independently. The fact box shows a spinner with “Finding entity…” while resolution runs, then “Loading facts…” while the entity payload is fetched, then the rendered card.
Understand the fact box layout
Section titled “Understand the fact box layout”When resolution succeeds, the panel renders in four stacked sections:
Header
- A thumbnail (from Wikidata’s P18 “image” property, served via Commons)
- The canonical label in your UI language
- The one-line description from Wikidata
- A QID badge that opens
wikidata.org/wiki/Q…in a new tab
Grouped facts
Curated per entity type. Example for a person:
- Life — date of birth, date of death, place of birth, place of death, citizenship
- Career — occupation, educated at, employer, doctoral advisor, influenced by
- Relations — spouse, child
- Recognition — awards received, notable works
Dates are formatted with precision respected: day when Wikidata has it, month or year when the record is less specific. Multi-value properties (e.g., two citizenships) are joined with a middle-dot separator.
External IDs
A row of small chips for known authority records. Clickable ones open the external service directly:
- VIAF, ORCID, ISNI — scholarly and name authority IDs
- IMDB, MusicBrainz — entertainment
- GitHub, Twitter — online identity
- GND, LoC — library catalogs
Attribution footer
A single line: “Data from Wikidata · CC0”, with a link to the Wikidata entity page.
Pick the right entity when the name is ambiguous
Section titled “Pick the right entity when the name is ambiguous”Common names produce multiple candidates. When the resolver is not confident enough to auto-select, the panel switches to a picker:
- A short “Multiple matches — pick one:” header
- Up to 5 candidate rows, each showing: label, description, QID, confidence score
- Click any row to commit
Your pick is cached for 30 days and keyed on the entity text + ontology type. The next time the same entity appears in any vault with the same type, it resolves instantly to your chosen QID.
If you later realise the pick was wrong, clicking the node again currently re-loads the cached choice. Clearing browser storage for the extension resets all resolutions.
Work with different entity types
Section titled “Work with different entity types”Daneel maps your knowledge graph’s ontology labels to Wikidata’s class hierarchy so the reconciliation stage can filter candidates by type. Five pillars are recognized out of the box:
- Person — labels like
person,human,fictional_character,deity - Organization —
organization,company,university,political_party,sports_team,news_outlet - Place —
location,country,city,region,continent,body_of_water,mountain,building,monument - Creative work —
book,film,song,album,artwork,television_show,video_game - Event —
war,battle,election,revolution,treaty,conference
Custom ontology labels that don’t match any of the above still work: the reconciliation runs without a type filter, candidates come back ranked by label match, and the disambiguation picker shows top results.
Use the panel offline
Section titled “Use the panel offline”The fact box is gated by Offline Mode. When the switch is on:
- Cached entities still render. If you looked up Einstein yesterday and his payload is still fresh in
chrome.storage, the fact box loads normally from cache, no network needed. - New lookups show a paused notice. Clicking a node whose QID has never been resolved shows “OFFLINE MODE — Wikidata lookup is paused”.
- External ID chips still link. The chip URLs open wikidata.org and authority sites in a new tab; the extension itself issues no outbound call.
To pre-warm the cache before going offline, click through the entities you want to have ready while online.
Rate-limit behavior
Section titled “Rate-limit behavior”All calls to Wikidata and the reconciliation service share a three-slot concurrency limit. If you rapidly click through a dozen nodes, no more than three network requests run at a time. The rest queue silently.
If Wikimedia responds with a 429 (rate limited), the panel respects the Retry-After header and retries up to three times with exponential backoff. On repeated 429s the panel shows “Couldn’t reach Wikidata” — wait a minute and try again.
Cache lifetimes
Section titled “Cache lifetimes”Three separate caches keep the panel responsive:
- Resolutions (text + type → QID): 30 days for user-confirmed picks, 1 day for auto-selected
- Entity payloads (QID → full simplified claims): 7 days
- Label map (QID or property ID → human-readable label): LRU-capped at 5,000 entries, untimed
Labels change rarely, so the map grows monotonically across sessions until you hit the cap.
Close the panel
Section titled “Close the panel”Click the X in the panel header to dismiss the fact box. The Wikipedia panel stays open independently — you can dismiss either, both, or neither.
Closing the 3D graph view or switching documents clears the panel automatically.
Language
Section titled “Language”Version 1 is English only. The label on your node is resolved against English Wikidata labels, the fact box renders in English, and the cache is lang-unaware. Multilingual support is tracked for a later release.
