How are hierarchical non-geographical subjects like "Widgets--Andorra--18th century" expressed with 1 authority = 1 descriptor? --Andy >>> [log in to unmask] 12/17/04 6:00 PM >>> A new (preliminary) draft of MADS is available at: http://www.loc.gov/standards/mads/mads-preliminary-draft-2-dec-17.xsd Similar to the previous draft, there is a companion version of MODS imported, http://www.loc.gov/standards/mads/mods-for-mads.xsd a slight change from the earlier version, and still compatible with MODS 3.0 Some changes in this draft from the November 23 draft: 1. The following is now explicit in the schema: Each authority, related, or variant element has exactly one descriptor. Before, it could have more than one, but that was to accomodate name-title (so you included a name descriptor and a title descriptor) but aside from the name-title combination, there was no other case where it made sense to include more than one descriptor. What we've done is to add a nameTitle descriptor. (It combines name and title, and also includes role, which is applicable only for a name-title, and role is therefore removed from the name definion.) --Ray
