Web app for visualizing Wikidata items in the form of a timeline.
Developed on/for Chrome 44+. Firefox/IE also tested to be stable, but might have some issues.
When using WDQ, these properties are used for determining time:
- startTime: 'P577', 'P580', 'P569', 'P571'
- endTime: 'P577', 'P582', 'P570', 'P576'
If endTime is missing, applies a default value (see the defaultEndTime url parameter).
If startTime = endTime, displayed as a point.
Performs rounding when endtime is 'someValue'.
Valid on the timeline view and the new view.
Note: Boolean parameters are true for any value which is not "false".
| Name | Type | Default | Description |
|---|---|---|---|
| title | String | Untitled | Timeline's title. Useful so that your browser's history doesn't display the same thing for different timelines. |
| sparql | String | The SPARQL Query to use for the visualization. Expects the 1st variable to be items, 2nd to be labels, 3rd to be start time, and 4th to be end time (optional; see defaultEndTime parameter)). Try it/learn more at Wikidata Query Service. |
|
| wdq | String | The Wikidata Query from which to get items. See WDQ's Documentation for help. Note this is translated to SPARQL using WDQ2SPARQL, so some features might not be available. | |
| defaultEndTime | String | now | One of "now" or "start". (also useful for resolving P571(inception) ambiguity). |
| embed | Boolean | false | If true, optimizes view for embedding in an iframe. |
| widthOfYear | Number | widthOfYear | How many pixels wide a year should be on the timeline |
The url parameters work if the wdq is present.
| Name | Type | Default | Description |
|---|---|---|---|
| languages | CSV | en,fr | The languages to use, ordered by preference. If no label in the given lang(s), stays blank |
| sitelink | String | wikidata | What an item links to when clicked. Language determined by languages. Possible values: [ 'wikisource', 'commonswiki', 'wikibooks', 'wikiquote', 'wiki', 'wikinews', 'wikidata' ] |
| sitelinkFallback | Boolean | true | If true, when the desired sitelink is not available, links to wikidata. If false, links to nothing. |
Please do not use these parameters.
