Administrative Components Final version 2003, Jytte Hansen & Leif Andresen Updated January 2006 with an additional property (source) a practical tool for users of metadata to manage metadata with special focus on interoperability between different systems...for administration of metadata 23 properties in 3 categories: Metadata for the entire record Metadata for update and change Metadata for batch interchange of records
Properties About the metadata identifier source scope comment location language rights dateRange handling About change & update activity action name contact date affiliation
Properties 2 About transmission and interchange database transmitter fileName technicalFormat characterSet bibliographicFormat resultFile These are about transmission of the metadata records
