Open Data and the API (English)

A photo from the collection 'Bonda'

The Regionaal Archief Alkmaar wants to show as many people as possible the rich history of Alkmaar and other towns (Bergen, Castricum, Den Helder, Heerhugowaard, Heiloo, Hollands Kroon, Langedijk, Schagen en Texel) in the province of North-Holland in the Netherlands. We try to use different ways to do that. For example, we have a lot of photo's in our online image library that can be downloaded. You can read the conditions (Dutch) here.

API 

The Regionaal Archief Alkmaar also has an API (Application Programming Interface) to give you free access to some of our collections. This API has been made because of our participation in an Open Cultural Data (Dutch) initiative in the Netherlands. The collections are:

A page from the 'Album Amicorum'

The pictures in the API are marked "no known copyright restrictions" and "public domain" This means that we are unaware of any current copyright restrictions on the works so designated, either because the term of copyright may have expired without being renewed, because no evidence has been found that copyright restrictions apply, or because we own the copyright but are not exercising that control.” You can use them for commercial and non commercial works without premission from the Regional Archief Alkmaar. The information in the API consists of a hi resolution image (jpg2000) and information about the catalog number, location, description, date en annotation. 

When you use pictures from the above mentioned API we would appreciate it that you use our name as a source, but it is not compulsory.
