The City of Bergen's citizen portal is the city administration's main point of contact with the population, serving both as an information outlet and as an entry point to the services provided by the city to the population. The entire site is structured using a topic map offering multiple points of entry into the site. One entry point is using Los, a standardized taxonomy for local administrations published by the Norwegian government as a topic map. Another entry is the organizational structure of the city administration. Other entry points are provided by the site editors using the navigational menus and articles.

The site is run by Oracle Portal, with most of the structure contributed from Ontopia-based portlets, while the content is managed using the Escenic Content Engine. Much of the topic map structure is converted from an internal data warehouse using DB2TM to do nightly synchronization.
