Development of the Exhibition Object Data Exchange Model (EODEM) reached an important milestone yesterday with the formal release of version 1.1 of the LIDO data-sharing standard. This is significant because EODEM is defined as a profile of LIDO – that is, an EODEM record comprises a fixed sub-set of LIDO data elements and values. And this in turn means that, if a collections management system vendor implements a LIDO 1.1 importer or exporter, they will have done the bulk of the work required to produce an EODEM importer or exporter.
