Project e-documenta Pannonica will concern the insufficiency or professionally inconvenient interpretation and usage of data concerning cultural heritage of localities on the partnership territory. It will bring them public usage through project products. In this project we will establish strategic partnership of five cultural institutions, which will form an interdisciplinary base of credible archaeological, ethnological, cultural-historic and biographic data about cultural heritage of 120 places. General goals are: to increase the amount of competent data about cultural heritage, their public access and indirectly tourist visits. Localities’ cultural heritage database, which will be designed on joint methodology, will enable a promotion of smaller localities, quality improvement of their tourist offers and forming of new tourist contents. The product of the project will be a web portal in 3 languages with interactive map of localities, based on competent database, which will then transform data into general use. This portal, which will be accessible also through mobile app, will benefit organizers of tourist offers, local communities, schoolchildren, teachers, tourist guides and others. The basic outcomes are common, permanent and publicly accessible database as well as joint information office. Partnership of museums and archives, specialized for protection and interpretation of complex heritage, and tourist organizations, implementing these data into tourist offer, is crucial. It is essential for this project to include both sides of the border and to merge institutions and new and revised data of this bordering area by supporting the increase of their tourist offer. The fact that in museums and archives new collective database of cultural-historic data about localities will emerge is very innovative. This database will enable permanent usage of these data for different purposes.
