INCCA is an ongoing activity of the Rijksdienst voor het Cultureel Erfgoed (RCE) / Cultural Heritage Agency in the Netherlands. RCE is part of the Dutch Ministry of Education, Culture and Science. RCE provides the salary of the INCCA Coordinator as well as the hosting and development of the INCCA website. 

The content on www.incca.org is provided on a volunteer basis by INCCA members.  Most members work for organisations, such as museums, universities and conservation research institutes. These organisations are considered INCCA partners for the reason that they allow their employees to spend time sharing knowledge via the network. RCE is grateful to the generosity of all INCCA partners and of course for the hard work provided by individual members. Members of the INCCA Steering Committee and the  INCCA group coordinators also work on a volunteer basis. The INCCA network is not a legal entity and could be described as a volunteer network.



Yes. Freelance or private professionals are encouraged to join the network. Sharing a document through the INCCA website only takes a few minutes and doing so can be helpful to your practice, but also to others in the field!

Often freelancers are unsure if they are allowed to share documents they collect and create. It is up to the individual member to ensure that they have the proper permission from their clients (museum, private collector, artist) to upload information into the member document section of the website. 

For this purpose a generic permission form has been created which can be useful for freelancers. The form canbe found in the member document section. Enter the term 'useage' and click search.

INCCA loosely defines modern art as artistic works from the late 19th century though the 1960s. Modern art is often experimental and frequently abstract. Contemporary art is considered to have begun in the 1960s, as artists challenged the concerns of modern artists and questioned the definition of art itself. Given the complex nature of artistic movements during this period, INCCA adopts broad definitions of these terms and relies on its members to decide what, for instance, qualifies as appropriate art for its Database.
