Timeline

The timeline displays either everything time-bound or is a display format for a specific component, like Events. If there is only one timeline per page, there must be elaborate settings to configure what is shown on the timeline.

Timelines

Basic timeline

A basic timeline is text-based. It displays event items as well as auxiliary items based on dates only. An event based on an item can be accessed through a link. For topics that are only based on a date, an item can be created. The timeline can display the event as a point in time or a time span. It can be zoomed and scrolled horizontally in time. It displays events by row, earliest on top. The events can be scrolled vertically when there are more events than fit the frame. Events can also be filtered.

Combined timeline

Gallery

A gallery can be joined with a basic timeline to provide a more visual display. Gallery in the events component is based on dates in addition to event items. Gallery topics link to the event's topic pages when the event is based on an event item. An item can be created for topics that are only based on a date.

A gallery can slide horizontally to match the event on the timeline. The gallery item's display

The timeline can read external sources and display them federated with local items. For external items, adding the data to Wikidata/Wikidocumentaries will be made possible.

A basic gallery in any component can be considered a timeline when the items are sorted by time. See also Gallery.

Editing events

BiographySampo extracts sentences about events in the Finnish National Biographies. They contain structured information about the related actors and the date. These sentences can be read via SPARQL and arranged on a timeline. The following is a scenario of a crowdsourcing interface to turn those sentences into structured data.
