Lightweight Information Describing Objects

LIDO is an XML harvesting schema. LIDO is a 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 with its ability to represent the full range of descriptive information about museum objects. It can be used for all kinds of object, e.g. art, cultural, technology and natural science. It supports multilingual portal environments.
