Museums preserve, study and display heritage. They are also the first to spot suspect works and to record the condition of collections. OIMAP therefore cooperates with a network of museum institutions, national or private, around the world.

For the list of network members, see the Museums page. Museums also take part in the exhibitions organized with the Organization.

The role of museums

Museums hold collections whose provenance must be documented. They have laboratories, libraries and networks of researchers, and they welcome the public. Their voice is essential for raising awareness of the issues of trafficking and restitution.

Their cooperation with OIMAP makes it possible to harmonize acquisition, documentation and loan practices between countries.

Shared expertise

Partner institutions make curators and restorers available for ad hoc opinions. These experts may be accredited by the Organization and listed in the directory of experts.

They are bound by the code of ethics, which notably forbids appraising a work in which one has a direct interest.

Restitutions and mediation

When an object is claimed by a State or a community, the holding museum is a central player. OIMAP offers a mediation that brings the parties together, examines the evidence and seeks an acceptable solution: restitution, long-term loan or joint study ownership.

Partner museums undertake to examine any documented request in good faith and not to conceal information about provenance.

Training of professionals

Training cycles are organized for curators, registrars and documentalists. They cover provenance research, management of donations, international loans and verification of export documents.

Partner establishments host trainees from the OIMAP Academy, who thus discover varied practices from one country to another.
