The commentary by Derrfuss and Mar (2009) discusses some of the limitations of the present databases and calls for a universal coordinate database. Here I discuss further issues and propose another angle to the solution of a universal coordinate database with the use of wiki technology. The commentary by Derrfuss and Mar (2009) in NeuroImage shows how far the present coordinate databases lag behind the published literature and the two authors call for a universal coordinate database. Since 1998 we have gained some experience in the area by working both with the BrainMap and the Brede coordinate databases, and apart from the issues mentioned by Derrfuss and Mar I would like to raise three additional concerns: Ownership, extensibility and community involvement. A recent dispute has brought forth the issue of ownership to primary neuroimaging data within-laboratory (Fox et al., 2009) but disputes with neuroimaging data sharing between laboratories has a longer history (Aldhous, 2000). The issue of ownership of analysis results and meta-data, such as bibliographic information, would also be present for a coordinate database. U.S. National Library of Medicine claims ownership and imposes restrictions
