Teledoc and Unique Doc. IDs etc

[[e-mail]]

 Some information was recently sent to the IETF list re Teledoc - which
 is the International Telecommunication Union's Document Delivery
 Project.

 The following taken from a doc.  on their project may be of interest
 to this group:


      " Fortuitously, after the project was started in the beginning of
      1992, a new International Standard was published that provided a
      conceptual model for the document reference system.  This was the
      International Organization for Standardization's (ISO)) Document
      Filing and Retrieval Standard (ISO 10166) more commonly known as
      DFR.  To quote from the introduction of this standard:

           "The Document Filing and Retrieval (DFR) application
           provides the capability for large capacity non-volatile
           document storage to multiple users in a distributed office
           system..

           Documents have associated attributes, to facilitate and
           control retrieval.  Use of these attributes according to
           given algorithms will enable documents in the document
           storage to be browsed, retrieved, managed and deleted in a
           variety of ways.  Access control protects documents from
           unauthorized operations.  Documents can be stored in nested
           groups.  With specific attributes a document can be
           designated a version of another document.  Single documents,
           references or groups can be moved from one group into
           another group.  Enumeration of groups, identification by
           other attributes besides names, identification by conditions
           over attributes, search for documents meeting search
           criteria, concurrent access to the same documents, reference
           or group of documents are further functions provided by this
           standard for the user requirements in an office
           environment."
                              "

 Then later:


      " Support for "conceptual document" which links together multiple
      stored format versions of the same document.  For example, one
      conceptual document may have Word for Windows, Rich Text Format,
      ODIF, and Postscript stored representations.

      DFR Unique Permanent Identifiers (UPIs) for groups and documents
      is key value generated by the SQL database.  The project team
      will follow evolution in this area (discussions by Internet
      Engineering Task Force group on Network Information Resources,
      ISBN's - ISO DIS 2018)."
