The aim of this scholarly blog is to provide a single space where the progress made on the definition of an heritage data reuse charter can be recorded and documented. This charter is targeted towards researchers, cultural heritage institution as well as any organisation for which the issue of data reuse for research can be relevant. After an initial impetus provided by the European research infrastructure DARIAH, several institutions have joined the effort: CLARIN, E-RIHS, APEF, LIBER.
