LAUDATIO aims to build an open access research data repository for historical linguistic data with respect to the above mentioned requirements of historical corpus linguistics. For the access and (re-)use of historical linguistic data the LAUDATIO repository uses a flexible and appropriate documentation schema with a subset of TEI customized by TEI-ODD. The extensive metadata schema contains information about the preparation and checking methods applied to the data, tools, formats and annotation guidelines used in the project, as well as bibliographic metadata, and information on the research context (e.g. the research project). To provide complex and comprehensive search in the linguistic annotation data, the linguistic search and visualization tool ANNIS will be integrated in the LAUDATIO repository infrastructure.
