The OLAC Metadata Set extends the Dublin Core set only to the minimum degree required to express those basic properties of language resources which are useful as finding aids. All fifteen Dublin Core elements are used in the OLAC Metadata Set. In order to suit the specific needs of the language resources community, the elements have been ``qualified'' following principles articulated in ``Dublin Core Qualifiers'' [DCMI2000], and explained below. This section lists the OLAC metadata elements and controlled vocabularies. Full details are available from [www.language-archives.org].
