          Textual Representation of IPFIX Abstract Data Types
                    draft-ietf-ipfix-text-adt-04.txt

Abstract

   This document defines UTF-8 representations for IPFIX abstract data
   types, to support interoperable usage of the IPFIX Information
   Elements with protocols based on textual encodings.

1.  Introduction

   The IPFIX Information Model[RFC7012] provides a set of abstract data
   types for the IANA IPFIX Information Element Registry [IANA-IPFIX],
   which contains a rich set of Information Elements for description of
   information about network entities and network traffic data, and
   abstract data types for these Information Elements.  The IPFIX
   Protocol Specification [RFC7011], in turn, defines a big-endian
   binary encoding for these abstract data types suitable for use with
   the IPFIX Protocol.

   However, present and future operations and management protocols and
   applications may use textual encodings, and generic framing and
   structure, as in JSON or XML.  A definition of canonical textual
   encodings for the IPFIX abstract data types would allow this set of
   Information Elements to be used for such applications, and for these
   applications to interoperate with IPFIX applications at the
   Information Element definition level.

   In most cases where a textual representation will be used, an
   explicit tradeoff is made for human readability or manipulability
