Methods and systems for tracking document lineage
Systems and methods for managing data, such as metadata, are disclosed. In one exemplary method, metadata representing a document lineage are stored, and the stored metadata are searched. The metadata representing a document lineage may comprise a document identifier, identifying a collection of related documents; a file identifier, identify document branches in the collection of related documents; and version identifier, identifying a version of document within a branch of documents. The searching of metadata allows the identifying and tracking of document lineage through modification and duplication operations. Other methods are described and data processing systems and machine readable media are also described.
