The sharing of data via internet technologies is an obvious and basic principle of our information society today. Based on data accessible free of charge by initiatives Open Data or INSPIRE we are able to observe the independent development of thousands and millions of large and small scale internet applications for traditional web or smartphones. In contrary to the growing amount of data accessible in the web and requested by a wide range of users and developers, it can be stated without doubt that archaeological data are still widely unpublished. Even if forward-looking projects can be observed in certain countries or regions the overall development of digital archaeological data across Europe shows no significant step forward towards an active sharing of data. In contrary to this lack of development we can observe that data resp. information from the field of cultural heritage and especially archaeology is particular demanded by the public and private sector. Information from this field may be part of a high number of applications for different use cases such as tourism or education.
