Trade wg efforts

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.

    • Status: Informational Version 1 Done. Need token document for SRV RR use. Need Author/Editor/Energy for Version 2.

Trade wg efforts1

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.

    • Version 2 is generalized and XML oriented.

    • Status: Version 2 Proposed Standard submitted.

Trade wg efforts2

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.

    • Status: Version 1 Proposed Standard submitted.

Document Status (cont.)

  • Active Documents in the Working Group

    • DNS SRV Location of Higher Level Services

      • draft-ietf-trade-srv-higher-services-00.txt

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

    • See RFC 2782.

Iotp use of dns srv rr1


  • 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


  • To provide separate search for IOTP services, we need to define tokens such as _iotp-merchant, _iotp-payment, _iotp-delivery, and _iotp-care.

    • _iotp-payment._http._tcp.merchant.example

Sccd and iotp v2

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

    • Can use ECML syntax.


  • 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.
