This paper describes the need for new infrastructures for future eScience scenarios in the humanities. Three projects working on different aspects of these infrastructures are examined in detail. The first project is trying to achieve a federation of archives, developing an integration layer at the level of localization, access to and referring to an archive’s raw data objects. The other two try to achieve interoperability at the level of semantic interpretation of linguistic data-types and tagging systems. The project’s different approaches to this problem show the trade-of between flexibility and the user’s workload. All three approaches give an impression about the necessary steps to come to an eHumanities scenario
