To solve troublesome interoperability problems by using various metadata formats,
a Common Terminology (CT) of MARC, MODS, DC and QDC is suggested.
The goal of the CT is to embrace diversity of metadata formats fulfilling needs of many communities, and
to provide uniformity to achieve and improve interoperability minimizing loss information and keeping accurate information.
The CT of MARC and (Q)DC is a set of 12 Common Terms:
contributor, date, description, format, identifier, language,
publisher, relation, right, subject, title, typeGenre.
The CT has the reduced common terms than DC, but has more qualifiers/attributes than QDC
so that it can preserve much information from MARC and MODS.
That is to say, it is to achieve and improve metadata interoperability addressing existing
loss of data problems by different generality or specialty degrees, and addressing lack of standardizations.
