Document fragments are managed by the use of fragment objects. Fragment objects contain a reference to a portion of a source document. Referencing documents contain a reference to a fragment object which delivers the content of the fragment of the source document to the referencing document. The source document can be directly updated through updating the fragment of the source document contained in the referencing document via the use of the fragment object. Source document deletion is controlled by storing the references to the source document by fragment objects so that no fragment object has a reference to a non-existent source document. A process for organizing document fragments within a document management system wherein source documents comprise duplicates of the document fragments includes replacing a duplicate fragment with a reference to a single fragment object the fragment object including a reference to a fragment of a source document and an object class method for deletion of the fragment object including instructions to remove the reference to the fragment object from the metadata of the source document to which the fragment object refers. |
