From 21 January 2012 to 3 June 2012, the Teylers Multilingual Challenge was won by Lodewijk Gelauff (Effeietsanders). It was a Wikipedia writing challenge for the Teylers Museum in Haarlem, the Netherlands, based on the template created by the Wright Challenge. At the end of the challenge there were over 600 articles on Teylers related subjects in 13 different language wikipedias: en (203), nl (141), ca (103), hu (40), fr (36), es (19), it (19), de (17), ru (6), uk (6), fy (5), pt (4), eo (2). Roughly half of the articles were new, and a large selection of the rest were expanded or linked in some way to Teylers core articles. The Wikipedia article Martin van Marum was created and promoted to Feature article status in Catalan by second prize winner Davidpar.

Dutch National Archive content donation
The Dutch National Archives are going to release another 140,000 images on Dutch news events from 1959-1989 into the public domain under the license CC-by-SA. They previously released 1,000 images in an earlier pilot project together with Spaarnestad Photo of Dutch politicians. The photos will be from the ANeFo collection (General Dutch Photo Agency) and are not just politically focussed, but encompass general news events from 1945 to 1989. The meta data will be released under the license CC-0, but as many photos lack attribution, this means they will not be able to be used on Wikimedia Commons.
Though a lot of work will need to be done on Wikimedia Commons to use some images fully due to incomplete descriptions, this is still a great step forward for illustrating Dutch history on Wikipedia. It seems the release was done in the context of the 'Hack the Government' Open Data initiatives. More information in Dutch on "Hack" de Overheid. The National Archives have also announced a contest for using the images in an app. More information in Dutch on National Archief website.
The first release of the 140.000 images was a XML datadump with limited (Dublin Core) metadata fields. Recently, for this collection an open search api (www.opensearch.org) is developped. In its output attribution is available.
