Does anybody really use IOTP?


Related to this, I have one question more: Is there any implementation available?

Regards,
Antonio.

Does anybody use ECML?
Regarding ECML I believe it is built on bad idea from a security/privacy point 
of view
as attributes should be released by the user in a controlled way and that is in 
conflict
with an arbitrary HTML page.  In a "competing" standard I am involved with,
we scrapped ECML for a set of attribute enquiry schemes which is much easier to
implement GUI-wise (giving a predictable and consistent behavior) and does
not lump together disparate data like payment instruments and shipping 
addresses.

Subject: Payment Application Programmers Interface (API) for IOTP



recently published RFC http://www.garlic.com/~lynn/rfcidx12.htm#3867

3867 I
   Payment Application Programmers Interface (API) for v1.0 Internet Open
Trading Protocol (IOTP), Beykirch H., Hiroya M., Kawatsura Y., 2004/11/05
(106pp) (.txt=234572) (Refs 1738, 2246, 2801, 3538) (was
draft-ietf-trade-iotp-v1.0-papi-06.txt)

clicking on the ".txt" field in the summary retrieves the actual RFC.
clicking on any of the referenced RFCs goes to the summary for that RFC ...
I got a request during Crypto 2004 for more complete indexing in the wake
of trying to find all references related to MD5 ... so I finally got around
to addeding document refs to the summary field. and somewhat aside ...
generated a brand new set of summaries just related to MD5
http://www.garlic.com/~lynn/rfcmd5.htm

this is another publication of the IOTP working group of the IETF. Long ago
and far away the group started out as trying to map Mondex to Internet
environment. Other works that the IOTP working group has done is ECML.

if you click on the actual RFC number in the summary, it brings up all the
ways the RFC is indexed; i.e.

3867 - Internet Open Trading Protocol, application program interface

if you click on "Internet Open Trading Protocol", you get the list of all
the RFCs from that working group (or at least the list since I started
tracking/keeping RFCs by working group) ... aka:

Internet Open Trading Protocol
   3867 3506 3505 3504 3354

and the respective summaries:

3506
   Requirements and Design for Voucher Trading System (VTS), Eastlake D.,
Fujimura K., 2003/03/13 (15pp) (.txt=30945) (Refs 2801)

3505 I

Eastlake D., 2003/03/13 (8pp) (.txt=13915) (Refs 2246, 2801, 3106)
