A document log is an ordered list of entries providing a history for any sort of media or file, just as a logfile provides a history of a computer program and a logbook provides a history of a journey. The history of a document may consist of copyright information, approvals, annotations, or any sort of metadata. This paper describes a metadata architecture using Content Based Identifiers and Document Logs that facilitates location of metadata from distributed sources, caching, ordering of log entries, and detection of changes in metadata or documents. The techniques used complement existing metadata format standards and are contrasted with storage of metadata in a file or document management system.
