  As part of ongoing research projects, three Jagiellonian University units --
the Jagiellonian University Museum, the Jagiellonian University Archives, and
the Jagiellonian Library -- are collaborating to digitize cultural heritage
documents, describe them in detail, and then integrate these descriptions into
a linked data cloud. Achieving this goal requires, as a first step, the
development of a metadata model that, on the one hand, complies with existing
standards, on the other hand, allows interoperability with other systems, and
on the third, captures all the elements of description established by the
curators of the collections. In this paper, we present a report on the current
status of the work, in which we outline the most important requirements for the
data model under development and then make a detailed comparison with the two
standards that are the most relevant from the point of view of collections:
Europeana Data Model used in Europeana and Encoded Archival Description used in
Kalliope.
