[MIB2RDML] SNMP MIB to XSD mapping I-D available

["Natale, Bob" <RNATALE at mitre.org>]

Hi,

 

For those of you on the MIB2RMDL list who have been wondering what (if anything!) has been going on during this long period of silence on the e-mail list, and for others interested in having an IETF standard methodology for mapping SNMP MIBs to XML via XSD for generic use by XML-based management applications, I can now report some progress.

 

That progress is best represented by a new Internet Draft which is now available at http://home.comcast.net/~bobnatale/draft-li-natale-smi-datatypes-in-xsd-00.txt, pending posting to the IETF I-D repository following the imminent Vancouver IETF meeting.

 

Dave Harrington has led this effort, starting with the XSDMI proposal at the Chicago IETF meeting.  As I published on this list around that time, it makes sense for the MIB2RMDL effort to see XSDMI as the essential first half of the equation (i.e., the "MIB2->" part) of MIB2RMDL.  Once the IETF publishes a standard methodology for the _expression_ of management information described in and accessible via SNMP Management Information Bases (MIBs) as XML documents, then other groups (if desired) can undertake the second half (i.e., the "->2RMDL" part).  (Note that this approach also allows for multiple resource model mappings from the standard MIB to XSD mapping.)  Yan Li did much of the concrete research of multiple existing independent approaches for doing the fundamental datatypes mapping addressed in this draft.  We then did a comparative analysis of those approaches, relative to the requirements stipulated in Sec. 3 of this draft, as a baseline for the specific approach this draft proposes.  This draft originated from draft-romascanu-netconf-datatypes, but now bears little resemblance to that document, due to differences in scope, structure, and content.

 

Any errors or otherwise errant statements in the draft are purely my responsibility.

 

I believe that the OPS ADs plan to allocate some agenda time to discuss this work at the Vancouver IETF.  I will post that scheduling info when it becomes available, and I will do a post-Vancouver recap message as soon after IETF-70 as possible.

 

In the meantime, please feel free to raise any issues or post any comments concerning the draft or the plans here and on the ops-area list (unless the ADs give other guidance about which list(s) to use).

 

Cheers,

BobN
