  The objective of this paper is to present a meta-corpus of diplomatic
documents entitled Cartae Europae Medii Aevi or CEMA. It shows the logic and
limits of this meta-corpus, which contains 250,000 documents, by specifying
both its structure and its possible future extensions. The second part of the
paper is devoted to specific examples that will attempt to show the interest of
such a database. The third part examine the possibilities opened up by the
corpus in terms of historical semantics.
