This result format is not currently maintained. It might not work with the latest version of Semantic MediaWiki.

The result format eventline are used to display query results in interactive eventlines. This format was part of Semantic MediaWiki until Semantic MediaWiki 1.3.0Released on 7 September 2008 and compatible with MW 1.12.x - 1.15.x. and is now part of extension "Semantic Result Formats"Provides additional formats for semantic queries. Obviously, only results that include dates can be displayed in this way. This format only works when JavaScript is enabled. It is similar to the timeline format.


The eventline format uses printout statements in queries for properties of datatype "Date"Holds particular points in time. If the eventline remains empty even though there are results, this is usually because no printouts for dates were specified. Eventline will display all dates in the printout as separate points. So a query with five data printouts would create five points on the eventline for each result. Different colors are used to maintain some visual hint of which points belong to which result. Again the tooltip shows all details. All other printout statements are shown in the tooltips that appear when clicking on items.

This produces the following output:


Page load times can be slowed down by eventlines, especially if a large number of events is displayed. It is useful to use a smaller limit to keep the eventline more manageable for browsers.

Sorting results has no impact on the display of the timeline, since it always displays events chronologically. However, sorting can be very useful to select, e.g., the ten latest events instead of ten arbitrary events for display.
