The Library of Congress' Network Development and MARC Standards
Office, in partnership with the NISO
Technical Metadata for Digital Still Images Standards Committee and
other interested experts, is developing an XML schema for a set of
technical data elements required to manage digital image collections.
The schema provides a format for interchange and/or storage of the
data specified in the Data
Dictionary - Technical Metadata for Digital Still Images (ANSI/NISO
Z39.87-2006). This schema is currently referred to as "NISO
Metadata for Images in XML (NISO MIX)".
MIX is expressed using the XML
schema language of
the World Wide Web Consortium. MIX
is maintained for NISO by the Network
Development and MARC Standards Office of the Library of Congress
with input from users.
2.0 is now the current version of MIX.
