The Museum of Mankind library and pictorial archive staff are currently working on the ethnic group terms. Work is also underway on geographical place names. Ethno collections done first and not updated for 5 years. Flat list used with multiple entries possible per object. Have a separate field for categories as opposed to simple names.
All fields can have multiple entries.
They use the Blackwood system, with multiple classification entries per object. They are working on a hierarchical materials list and a flat list for processes. Entries are usually made to catalogue level. All fields have on-line controlled terminology. Early work on materials and processes has stopped, and we will look to outside sources immediately rather then develop these further.
