ISO/IEC 19785-3:2007 specifies several patron formats that conform to the requirements of ISO/IEC 19785-1.

ISO/IEC 19785-1 defines a basic structure for standardized biometric information records (BIRs) that consists of three parts, the standard biometric header (SBH), the biometric data block (BDB), and the security block (SB). CBEFF also defines several data elements and their standardized abstract values that can be used in SBHs and SBs (CBEFF treats the BDB as opaque data). CBEFF also establishes mechanisms by which organizations, called “patrons” by CBEFF, can specify and publish BIR format specifications, which are in turn called “patron formats”. CBEFF enables patrons to develop BIR specifications that are fully standardized and interoperable, yet are specifically adapted to the requirements of a particular application environment.

CBEFF defines rules for BIRs that contain only one BDB (simple BIR) and that contain at least one BDB (complex BIR). CBEFF defines mandatory data elements that identify the format of a BDB and its security attributes (encryption and integrity). All the other CBEFF-defined data elements and abstract values are optional. CBEFF enables patrons to define additional data elements and abstract values as required by the application environment

This Standard defines the characteristics of 90 mm Optical Disk Cartridges (ODC) with a capacity of 2,3 GB per Cartridge. The Standard specifies only Type R/W for 2 048-byte sectors of such cartridge. Type R/W provides for data to be written, read and erased many times over the entire recording surface of the disk using the thermo-magnetic and magneto-optical effects. It is also referred to as "fully rewritable". This International Standard provides for 2 048-byte sectors only. All sectors on a disk are of the same size.

This Recommendation | Standard specifies the messages and encodings that enable the use of Fast Web Services, together with the means of description of such services.The protocol used to support these services satisfies the requirements of the SOAP processing model (see W3C SOAP Part 1, clause 2) and is based on the transfer of:a) ASN.1 SOAP messages that contain embedded ASN.1 encoded values and embedded fast infoset documents; andb) fast infoset SOAP messages.This Recommendation | Standard also specifies:?an ASN.1 module for ASN.1 SOAP that defines the Envelope type (a value of this type corresponds to an ASN.1 SOAP message);?a conceptual mapping between ASN.1 SOAP messages and W3C SOAP messages (defined as an instance of the XML Infoset, see W3C SOAP Part 1, clause 5);?an extension to the W3C SOAP processing model for the processing of embedded ASN.1 encoded values;?the ASN.1 SOAP HTTP Binding, which is a modification and extension of the W3C SOAP HTTP Binding (see W3C SOAP Part 2, clause 7), for the transfer of ASN.1 SOAP messages;?support for the transfer of W3C SOAP message infosets serialized as fast infoset documents (fast infoset SOAP messages) using the W3C SOAP HTTP Binding (see W3C SOAP Part 2, clause 7);?SOAP-oriented service descriptions that define the interface to and the semantics of Fast Web Services.Two Multipurpose Internet Mail Extensions (MIME) media type names are allocated to identify:?ASN.1 SOAP messages encoded using Basic Aligned PER;?fast infoset SOAP messages.

Specifies the operating conditions of an integrated circuit card that provides a USB interface. An integrated circuit card with a USB interface is named USB-ICC. Specifies the electrical conditions when a USB-ICC is operated by an interface device - for those contact fields that are not used, when the USB interface is applied; the USB standard descriptors and the USB-ICC class specific descriptor; the data transfer between host and USB-ICC using bulk transfers or control transfers; the control transfers which allow two different protocols named version A and version B; the (optional) interrupt transfers to indicate asynchronous events; status and error conditions.
