Subject: [xcbf] Initial TC Request
Here's a complete copy of what I sent to OASIS. A few things were changed before it was accepted and the call for participation went out. But I thought that you all might like to have a look. It is essentially our charter. Phil Name of the TC The name of the technical committee is OASIS TC "XML Common Biometric Format", usually abbreviated as the XCBF TC. Statement of purpose This Technical Committee will define a common set of XML 1.0 encodings for the patron formats defined in CBEFF, the Common Biometric Exchange File Format (NISTIR 6529, available at http://www.nist.gov/NISTIR-6529-CBEFF). These formats will be specified in accordance with the ASN.1 schema definitions published in ANS X9.84:2000 Biometrics Information Management and Security For The Financial Services Industry© (available from the ANSI electronic bookstore at http://www.ansi.org). The Common Biometric Exchange File Format defines a common set of data elements necessary to support multiple biometric technologies and to promote interoperability of biometric- based application programs and systems by allowing for biometric data exchange. CBEFF describes a set of "required" and "optional" data fields, a "domain of use", and "CBEFF Patron" formats that utilize some combination of these standard elements. Patron formats specify encoding of the data elements and any additional (non-common) data elements. The two defined CBEFF Patron formats are the BioAPI Biometric Identification Record (BIR) format specified in the BioAPI Consortium BioAPI Specification Version 1.0 and the X9.84:2000 BiometricSyntax type. But all of the encoding formats defined in CBEFF and X9.84 are binary encodings, making their use in XML systems and applications limited or difficult. A common XML schema that can carry the values in all of the CBEFF standard elements will promote the ability to exchange biometric information, between users of binary patron formats, and with XML-aware applications and systems. As new patron formats are added to CBEFF in future revisions, a common XML schema based on the X9.84 definitions should make it possible to exchange data with applications implemented using earlier versions of CBEFF. Common, underlying type definitions will allow information to be validated and exchanged without ambiguity. The exact same values specified in binary encodings will be used in XML representations of these values. This feature of the work will serve to promote interoperable solutions. The canonical variant of the XML Encoding Rules (CXER) will produce inputs suitable for cryptographic enhancement of the XML representations of X9.84 biometric objects, but which in that standard are expected to be processed solely in binary. All processing and security requirements used by this TC will be harmonized with standardization of the XML formats of CMS messages undertaken by ANSI X9F working groups. ------------------------------------------------------------ Proposed list of deliverables and projected dates * Published document defining the ASN.1/XML CBEFF schema, an introduction and overview of canonical DER, PER, and XER, and the processing and security requirements needed for the creation and verification of all cryptographic types defined in X9.84, in the form of XML encoded objects * Published working module including ASN.1 XML Markup Value Notation examples of X9.84 biometric types defined in the CBEFF standard, along with the underlying ASN.1 schema * Published example DER, PER and XER encodings of values of X9.84 biometric types and equivalent BIR encodings * Published documentation of new CBEFF patron formats that may become standard during the period of this work, in particular an anticipated smart card patron format * Initial drafts of all deliverables: May 30 2002 * Draft version of working module: November 2002 * Draft version of example binary encodings of XML values: March 2003 * Draft final versions of all remaining deliverables: May 2003 * Final versions of any new CBEFF formats: July 2003 * Final versions of all deliverables: November 2003 In order to achieve maximum interoperability between the efforts of various standards organizations, these XCBF deliverables may depend on work being done by ANSI X9F working groups and the new INCITS M1 Biometrics TC, so the completion of these deliverables may be affected by delays (if any) in the work of these groups. Though the schedule extends into November 2003, it is hoped that this work can be concluded no later than May 2003. Language in which the TC will conduct business: English. Speakers of other languages are encouraged to participate. Date, time, and place of first meeting Monday March 18 - Conference call at 7:00 pm. All interested UBL attendees will meet for the call in the Hotel Barcelona Universal, Barcelona, Spain Proposed meeting schedule for the first year * Monday March 18, 2002, 7:00 pm, Barcelona, Spain * Thursday, May 16, 2002, Somerset, NJ USA. * Thursday, August 22, 2002, Net Meeting/conference call * Tuesday, November 19, 2002, Geneva, Switzerland (just prior to the ITU-T SG17 meeting) * Further dates for 2003 to be announced Names and email addresses of proposing members Phillip H.
