LIDO is an XML schema intended for delivering metadata, for use in a variety of online services, from an organization’s online collections database to portals of aggregated resources, as well as exposing, sharing, and connecting data on the web. Its strength lies in its ability to support the typical range of descriptive information about objects of material culture. It can be used for all kinds of objects, e.g., art, architecture, cultural history, history of technology, and natural history. LIDO supports multilingual application environments. Being an application of the CIDOC Conceptual Reference Model (CRM), LIDO is the result of a collaborative effort of international stakeholders in the museum sector, starting in 2008, to create a common solution for contributing cultural heritage content to portals and other repositories of aggregated resources. LIDO is maintained under the patronage of CIDOC - ICOM International Committee for Documentation.
