My name is Maarten Zeinstra, I am an open content advisor and web developer at Knowledgeland. With a background in software engineering and philosophy of technology, I am mainly interested in how technologies change in a knowledge economy. At Knowledgeland I'm involved in EuropeanaConnect, Communia, Creative Commons and Images for the Future projects. For these projects, I acts as a researcher and advisor in the field of social innovation, technology and copyright.

I do not consider myself a Wikimedian, but as a pragmatic and practical open content researcher.

Wikipedia Bootcamp

In January 2011 a collaboration between the Dutch project Images for the Future, The Amsterdam Museum, and Wikimedia Netherlands organized a Wikipedia bootcamp. During this Bootcamp we brought experienced editors of Wikipedia together with a group of about thirteen employees of Cultural Heritage Institutions to transfer knowledge and skills about editing pages on Wikipedia. The aim of the meeting was to make the employees more familiar with how Wikipedia works and what the community processes look like. This was done through a thorough introduction and a gradual workshop where the employees were asked to write articles, upload images and use them with the support of the experienced editors. The workshop resulted in a number of articles, but more importantly in a more thorough understanding of Wikipedia with the employees and a better understanding of the hurdles that cultural heritage institutions might encounter when editing the encyclopedia with the Wikipedia volunteers.

I was involved in organizing and coordination this event.

Wikimedia Hackathon

Europeana Hackathon

On April 1st and April 2nd I particpated in Europeana's first hackathon, where I teamed up with Multichill to develop a proof of concept Europeana->Wikimedia commons uploader.

Note: I also work for Europeana where I give advice on its Copyright framework and I develop public domain calculators.

Report 'National Archive Joins Wikipedia' Effects

The Dutch National Archive made more than 1.000 photos of Dutch politician available to Wikimedia Commons in the Dutch Digitization project 'Images for the Future'. I've researched and written a report on the effects of this ingestion by Wikimedia.

The report can be found here (Dutch)

Wiki Loves Art Publication (active project)

Together with some of my colleagues at Knowledgeland I am currently working on a publication for the 2009 version of Wiki Loves Art/NL. Expect this very nice book full of images later this year.
