Museu da Imagem e do Som do Rio de Janeiro (MIS RJ)
The Museu da Imagem e do Som do Rio de Janeiro (MIS RJ) announced that it began using Tainacan on 3 September 2022. The museum’s public announcement links to its Tainacan catalogue and describes searchable material from several collection areas, including historic radios, audiovisual records, sound recordings from the Dorival Caymmi collection and photographs of performers and broadcasters. This supports a documented implementation for public collection access. The announcement does not identify a predecessor platform, describe a data migration or specify metadata standards, so none is claimed. The case is distinct from IBRAM’s federal museum network: MIS RJ is administered by the State of Rio de Janeiro and is described by the museum as the first state museum in that government’s portfolio to use Tainacan.
