IETF 57, Vienna Slide 3 of 15 TRADE WG Efforts IOTP – Internet Open Trading Protocol –An XML syntax for shopping that Assumes no prior relationship between the customer and the merchant Is payment systems independent. (Payment messages are tunneled through IOTP.) Allows the merchant functions of shopping, payment acceptance, fulfillment, and customer care to be distributed to different host computers if desired.

IETF 57, Vienna Slide 4 of 15 TRADE WG Efforts IOTP (cont.) –Some IOTP message formats used by InterPay and Royal Bank of Canada. Also used by Hitachi in the Japanese SMILE project. –Status: Informational Version 1 Done. Need token document for SRV RR use. Need Author/Editor/Energy for SCCD. Need Author/Editor/Energy for Version 2.

IETF 57, Vienna Slide 5 of 15 TRADE WG Efforts ECML – Electronic Commerce Modeling Language –A standard naming and hierarchical structure for identity, shipping, and payment information between customers and merchants. –Version 1 was oriented to HTML Forms completion by wallet software. The field names defined are recognized by mainstream browsers. –Version 2 is generalized and XML oriented. –Status: Version 2 Proposed Standard Specification submitted.

IETF 57, Vienna Slide 6 of 15 TRADE WG Efforts XML Voucher –An XML syntax to describe a logical entity that represents a right to claim goods or services. –A voucher can be used to transfer a wide-range of electronic-values, including coupons, tickets, loyalty points, and gift certificates, which are often necessary to process in the course of payment and/or delivery transactions.

IETF 57, Vienna Slide 7 of 15 TRADE WG Efforts XML Voucher (cont.) –Progress is occurring towards deployment. A standard for using XML Voucher with infrared is being developed in the Infrared Data Association (IrDA). Members of that association should see the working draft of “Infrared Financial Messaging: Voucher Profile” –Status: Proposed Standard Specification and Informational API submitted.

IETF 57, Vienna Slide 10 of 15 Document Status, in WG Active Documents in the Working Group –IOTP DNS SRV Location of Higher Level Services draft-ietf-trade-srv-higher-services-00.txt

IETF 57, Vienna Slide 11 of 15 IOTP use of DNS SRV RR The service, or SRV, DNS resource record provides a facility for indicating where to find a particular service for a particular domain name. It is like MX for finding mail servers except: –It can map to different ports. –It can give different weights to different servers. –It uses a constructed name based on the service such as _ldap._tcp.example.com –See RFC 2782.

IETF 57, Vienna Slide 12 of 15 IOTP use of DNS SRV RR To extend this for higher level services such as IOTP and the XML Key Management Service (XKMS) draft-ietf-trade-srv-higher-services-00.txt extends the syntax to allow a third level such as _iotp._http._tcp.example.net. To provide separate search for IOTP services, we need to define tokens such as _iotp-merchant, _iotp-payment, _iotp-delivery, and _iotp-care. For example _iotp-payment._http._tcp.merch.example

IETF 57, Vienna Slide 13 of 15 SCCD and IOTP v2 SCCD – Secure Channel Credit Debit –Simple payment system to be tunneled through IOTP. –Equivalent to filling in a credit card form. –Probably uses ECML syntax. –NEED AUTHOR/EDITOR. IOTP v2 – Internet Open Trading Protocol –New version for Proposed Standard corresponding to the IOTP v2 Requirements RFC. –Can be one document or multiple documents. –NEED AUTHOR/EDITOR.

IETF 57, Vienna Slide 14 of 15 Future Actions/Meetings Needed: –Author/Editors for SCCD Specification IOTP v2 Specification Next IETF Meeting: –Minneapolis, Minnesota, November 9-14, 2003 –see info about meeting as it appears on the IETF web page
