Community of Interest (COI) Cooperation portal

The Community of Interest (COI) cooperation portal (known also as DNBL) is an online environment developed to foster NATO interoperability efforts. This portal is present on both NU and NS domains to improve and simplify collaboration on COI-related documents and facilitate dissemination among community's members and/or to wider communities.

The main objective of the portal is to be the entry point for interoperability related data either by hosting it or linking to other relevant NATO portals. The COI portal, operated by NATO Communications and Information Agency, is organized according to a Communities of Interest breakdown that offers each COI a controlled-access site for collaborative work (Initiatives sites) and a publishing environment (COI publishing sites) in order to reach wider audiences.

The COI cooperation portal provides also information on available C4ISR services offered by the NCI Agency.
