Information technology — ASN.1 encoding rules — Part 3: Specification of Encoding Control Notation (ECN)

This document defines a notation for specifying encodings of ASN.1 types or of parts of types. It provides several mechanisms for such specification, including: – direct specification of the encoding using standardized notation; – specification of the encoding by reference to standardized encoding rules; – specification of the encoding of an ASN.1 type by reference to an encoding structure; – specification of the encoding using non-ECN notation. It also provides the means to link the specification of encodings to the type definitions to which they are to be applied. ECN does not currently provide any support for specifications using the OID internationalized resource identifier type or the relative OID internationalized resource identifier type (see Rec. ITU-T X.680 | ISO/IEC 8824-1), and these are not referred to further in this Standard.

Information technology — ASN.1 encoding rules — Part 8: Specification of JavaScript Object Notation Encoding Rules (JER)

This document specifies a set of JavaScript Object Notation Encoding Rules (JER) that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1, Rec. ITU-T X.681 | ISO/IEC 8824-2, Rec. ITU-T X.682 | ISO/IEC 8824-3 and Rec. ITU-T X.683 | ISO/IEC 8824-4. It is implicit in the specification of these encoding rules that they are also to be used for decoding. The encoding rules specified in this document: – are used at the time of communication; – are intended for use in circumstances where interoperability with applications using JSON is the major concern in the choice of encoding rules; – allow the extension of an abstract syntax by addition of extra values for all forms of extensibility described in Rec. ITU-T X.680 | ISO/IEC 8824‑1. This document also specifies the syntax and semantics of JER encoding instructions, as well as the rules for their assignment and combination. JER encoding instructions can be used to control JER encoding for specific Abstract Syntax Notation One (ASN.1) types.

Information technology — ASN.1 encoding rules — Part 5: Mapping W3C XML schema definitions into ASN.1

This document specifies two versions of a mapping from any XSD Schema into an Abstract Syntax Notation One (ASN.1) schema. The ASN.1 schema for both versions support the same semantics and validate the same set of XML documents. This document specifies the final XER encoding instructions that are to be applied as part of the defined mapping to ASN.1 types, but does not specify which syntactic form is to be used for the specification of those final XER encoding instructions, or the order or manner of their assignment. NOTE – Implementers of tools generating these mappings may choose any syntactic form or order of assignment that results in the specified final XER encoding instructions being applied. Examples in this document generally use the type prefix form, but use of an XER Encoding Control Section may be preferred for the mapping of a complete XSD Schema, as a matter of style. There are different ways (syntactically) of assigning XER encoding instructions for use in EXTENDED-XER encodings (e.g., use of ASN.1 type prefix encoding instructions or use of an XER encoding control section). The choice of these syntactic forms is a matter of style and lies outside the scope of this document.

Information technology — ASN.1 encoding rules — Part 4: XML Encoding Rules (XER)

This document specifies a set of basic XML Encoding Rules (BASIC-XER) that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1 and Rec. ITU-T X.681 | ISO/IEC 8824-2. This document also specifies a set of Canonical XML Encoding Rules (CXER) which provide constraints on the basic XML Encoding Rules and produce a unique encoding for any given ASN.1 value. This document further specifies a set of extended XML Encoding Rules (EXTENDED-XER) which adds further encoders options, and also allows the ASN.1 specifier to vary the encoding that would be produced by BASIC-XER. It is implicit in the specification of these encoding rules that they are also used for decoding. The encoding rules specified in this document : – are used at the time of communication; – are intended for use in circumstances where displaying of values and/or processing them using commonly available XML tools (such as browsers) is the major concern in the choice of encoding rules; – allow the extension of an abstract syntax by addition of extra values for all forms of extensibility described in Rec. ITU-T X.680 | ISO/IEC 8824‑1. This document also specifies the syntax and semantics of XER encoding instructions, and the rules for their assignment and combination. XER encoding instructions can be used to control the EXTENDED-XER encoding for specific ASN.1 types.

Information technology — Abstract Syntax Notation One (ASN.1) — Part 1: Specification of basic notation

This document provides a standard notation called Abstract Syntax Notation One (ASN.1) that is used for the definition of data types, values, and constraints on data types. This document: – defines a number of simple types, with their tags, and specifies a notation for referencing these types and for specifying values of these types; – defines mechanisms for constructing new types from more basic types, and specifies a notation for defining such types and assigning them tags, and for specifying values of these types; – defines character sets (by reference to other Recommendations and/or International Standards) for use within ASN.1. The ASN.1 notation can be applied whenever it is necessary to define the abstract syntax of information. The ASN.1 notation is referenced by other standards which define encoding rules for the ASN.1 types.

Information technology — Telecommunications and information exchange between systems — WS-Session — Web services for application session services

ISO/IEC 25437:2012 specifies Web Services (in WSDL, in Clause 5) and SOAP bindings (in Clause 6) for the Application Session Services defined in ISO/IEC 22534. The Application Session Services allow Applications to create and maintain a relationship with Servers termed Application Session. The Web services specified herein, allow Service Requesters (Applications in ISO/IEC 22534) and Service Providers (Servers in ISO/IEC 22534) to create and maintain such Application Sessions. ISO/IEC 25437:2012 builds upon and imports the XML schema definitions from ISO/IEC 22534. The method of making the WSDL description of the specified services available to Service Provider and Requester is out of the scope of ISO/IEC 25437:2012. The Notification WSDL specifies the ApplicationSessionTerminated operation. The operation specifies one input message for the event notification that Service Requesters receive from the Service Provider. Service Requesters may also receive the event notifications from web services, e.g. ECMA-348, that use ISO/IEC 25437:2012 for session management.

Information technology — Generic applications of ASN.1: Fast infoset — Part 1:

ISO/IEC 24824-1:2007 specifies a representation of an instance of the W3C XML Information Set using binary encodings. These binary encodings are specified using the ASN.1 notation and the ASN.1 Encoding Control Notation (ECN). The technology specified in ISO/IEC 24824-1:2007 is called Fast Infoset. This technology provides an alternative to W3C XML syntax as a means of representing instances of the W3C XML Information Set. This representation generally provides smaller encoding sizes and faster processing than a W3C XML representation. ISO/IEC 24824-1:2007 specifies the use of several techniques that minimize the size of the encodings and that maximize the speed of creating and processing Fast Infoset documents. These techniques include the use of dynamic tables (for both character strings and qualified names), initial vocabularies and external vocabularies. ISO/IEC 24824-1:2007 also specifies a Multipurpose Internet Mail Extensions (MIME) media type that identifies a Fast Infoset document.

ISO/IEC 24824-2:2006(Main)
Information technology — Generic applications of ASN.1: Fast Web Services — Part 2:

ISO/IEC 24824-2:2006 specifies the messages required for Fast Web Services. It provides the specification of ASN.1 SOAP messages which carry the same semantics as W3C SOAP messages. The exchange of ASN.1 SOAP messages provides Fast Web Services. ISO/IEC 24824-2:2006 references other ASN.1 International Standards and the Web services specification W3C SOAP 1.2 to fully define application exchanges that use Web protocols and W3C SOAP functionality. This is an extension to the provision of Web services using W3C SOAP messages, without any change to the functionality of W3C SOAP and service description languages. The main change is to the use of compact and easily-processed binary encodings of XML data, rather than character encodings. The use of ISO/IEC 24824-2:2006 (with the ASN.1 SOAP messages encoded using the ASN.1 Packed Encoding Rules, PER) allows applications to provide Web services using messages that require less network bandwidth and less processing power (and hence provide a higher transaction processing rate) than use of the character encoding of XML data. ISO/IEC 24824-2:2006 also specifies a Multipurpose Internet Mail Extensions (MIME) media type that identifies an ASN.1 SOAP message encoded in PER. It also specifies a MIME media type that identifies a W3C SOAP message infoset encoded as a fast infoset document (see ISO/IEC 24824-1). Both of these encodings are used by ISO/IEC 24824-2:2006.

This Recommendation | International Standard specifies a set of JavaScript Object Notation Encoding Rules (JER) that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1, Rec. ITU-T X.681 | ISO/IEC 8824-2, Rec. ITU-T X.682 | ISO/IEC 8824-3, Rec. ITU-T X.683 | ISO/IEC 8824-4. It is implicit in the specification of these encoding rules that they are also to be used for decoding. The encoding rules specified in this Recommendation | International Standard: ? are used at the time of communication; ? are intended for use in circumstances where interoperability with applications using JSON is the major concern in the choice of encoding rules; ? allow the extension of an abstract syntax by addition of extra values for all forms of extensibility described in Rec. ITU-T X.680 | ISO/IEC 8824-1. This Recommendation | International Standard also specifies the syntax and semantics of JER encoding instructions, and the rules for their assignment and combination. JER encoding instructions can be used to control the JER encoding for specific ASN.1 types.

Information technology — Abstract Syntax Notation One (ASN.1): Specification of basic notation — Part 1:

ISO/IEC 8824-1:2015 provides a standard notation called Abstract Syntax Notation One (ASN.1) that is used for the definition of data types, values, and constraints on data types. ISO/IEC 8824-1:2015: - defines a number of simple types, with their tags, and specifies a notation for referencing these types and for specifying values of these types; - defines mechanisms for constructing new types from more basic types, and specifies a notation for defining such types and assigning them tags, and for specifying values of these types; - defines character sets (by reference to other Recommendations and/or International Standards) for use within ASN.1. The ASN.1 notation can be applied whenever it is necessary to define the abstract syntax of information. The ASN.1 notation is referenced by other standards which define encoding rules for the ASN.1 types.

Information technology — ASN.1 encoding rules: Specification of Basic Encoding Rules (BER), Canonical Encoding Rules (CER) and Distinguished Encoding Rules (DER) — Part 1:

ISO/IEC 8825-1:2015 specifies a set of basic encoding rules that may be used to derive the specification of a transfer syntax for values of types defined using the notation specified in Rec. ITU-T X.680 | ISO/IEC 8824-1, Rec. ITU-T X.681 | ISO/IEC 8824-2, Rec. ITU-T X.682 | ISO/IEC 8824-3, and Rec. ITU-T X.683 | ISO/IEC 8824-4, collectively referred to as Abstract Syntax Notation One or ASN.1. These basic encoding rules are also to be applied for decoding such a transfer syntax in order to identify the data values being transferred. It also specifies a set of canonical and distinguished encoding rules that restrict the encoding of values to just one of the alternatives provided by the basic encoding rules.

Information technology — ASN.1 encoding rules: Specification of Packed Encoding Rules (PER) — Part 2:

ISO/IEC 8825-2:2015 specifies a set of Packed Encoding Rules that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1. These Packed Encoding Rules are also to be applied for decoding such a transfer syntax in order to identify the data values being transferred. The encoding rules specified in this Recommendation | International Standard: - are used at the time of communication; - are intended for use in circumstances where minimizing the size of the representation of values is the major concern in the choice of encoding rules; - allow the extension of an abstract syntax by addition of extra values, preserving the encodings of the existing values, for all forms of extension described in Rec. ITU-T X.680 | ISO/IEC 8824‑1; - can be modified in accordance with the provisions of Rec. ITU-T X.695 | ISO/IEC 8825‑6.

Information technology — ASN.1 encoding rules: Specification of Encoding Control Notation (ECN) — Part 3:

ISO/IEC 8825-3:2015 defines a notation for specifying encodings of ASN.1 types or of parts of types. It provides several mechanisms for such specification, including: - direct specification of the encoding using standardized notation; - specification of the encoding by reference to standardized encoding rules; - specification of the encoding of an ASN.1 type by reference to an encoding structure; - specification of the encoding using non-ECN notation. It also provides the means to link the specification of encodings to the type definitions to which they are to be applied. ECN does not currently provide any support for specifications using the OID internationalized resource identifier type or the relative OID internationalized resource identifier type (see Rec. ITU-T X.680 | ISO/IEC 8824-1), and these are not referred to further in this Standard.

Information technology — ASN.1 encoding rules: XML Encoding Rules (XER) — Part 4:

ISO/IEC 8825-4:2015 specifies a set of basic XML Encoding Rules (BASIC-XER) that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1 and Rec. ITU-T X.681 | ISO/IEC 8824-2. This Recommendation | International Standard also specifies a set of Canonical XML Encoding Rules (CXER) which provide constraints on the basic XML Encoding Rules and produce a unique encoding for any given ASN.1 value. This Recommendation | International Standard further specifies a set of extended XML Encoding Rules (EXTENDED-XER) which adds further encoders options, and also allows the ASN.1 specifier to vary the encoding that would be produced by BASIC-XER. It is implicit in the specification of these encoding rules that they are also used for decoding. The encoding rules specified in this Recommendation | International Standard: - are used at the time of communication; - are intended for use in circumstances where displaying of values and/or processing them using commonly available XML tools (such as browsers) is the major concern in the choice of encoding rules; - allow the extension of an abstract syntax by addition of extra values for all forms of extensibility described in Rec. ITU-T X.680 | ISO/IEC 8824‑1. ISO/IEC 8825-4:2015 also specifies the syntax and semantics of XER encoding instructions, and the rules for their assignment and combination. XER encoding instructions can be used to control the EXTENDED-XER encoding for specific ASN.1 types.

Information technology — ASN.1 encoding rules: Mapping W3C XML schema definitions into ASN.1 — Part 5:

ISO/IEC 8825-5:2015 specifies two Versions of a mapping from any XSD Schema into an ASN.1 schema. The ASN.1 schema for both Versions support the same semantics and validate the same set of XML documents. ISO/IEC 8825-5:2015 specifies the final XER encoding instructions that are to be applied as part of the defined mapping to ASN.1 types, but does not specify which syntactic form is to be used for the specification of those final XER encoding instructions, or the order or manner of their assignment. NOTE ? Implementers of tools generating these mappings may choose any syntactic form or order of assignment that results in the specified final XER encoding instructions being applied. Examples in this Recommendation | International Standard generally use the type prefix form, but use of an XER Encoding Control Section may be preferred for the mapping of a complete XSD Schema, as a matter of style. There are different ways (syntactically) of assigning XER encoding instructions for use in EXTENDED-XER encodings (for example, use of ASN.1 type prefix encoding instructions or use of an XER encoding control section). The choice of these syntactic forms is a matter of style and is outside the scope of this Recommendation | International Standard.

ISO/IEC 25437:2009(Main)
Information technology — Telecommunications and information exchange between systems — WS-Session — Web services for application session services

ISO/IEC 25437:2009 specifies Web Services (in WSDL) and a SOAP binding for the Application Session Services defined in ISO/IEC 22534. The Application Session Services allow Applications to create and maintain a relationship with Servers termed Application Session. The Web services specified herein allow Service Requesters (Applications in ISO/IEC 22534) and Service Providers (Servers in ISO/IEC 22534) to create and maintain such Application Sessions. It builds upon and imports the XML schema definitions from ISO/IEC 22534. The method of making the WSDL description of the specified services available to Service Provider and Requester is out of the scope of ISO/IEC 25437:2009. The ApplicationSessionTerminated operation of ISO/IEC 25437:2009 is an outbound asynchronous event notification that Service Requesters receive from the Service Provider. Service Requester may also receive the event notification from web services, e.g. ECMA-348, that use ISO/IEC 25437:2009 for session management. ISO/IEC 25437:2009 specifies the event subscription and notification behaviors supported by the two defined Options. Additionally it specifies the event subscription mechanism using WS-Eventing, specifies the event subscription mechanism using WS-BaseNotification, specifies the asynchronous subscription response Option for the two event subscription mechanisms, shows an example WS-Session WSDL binding with SOAP/HTTP, lists SOAP XML Templates for ISO/IEC 22534 messages, lists some SOAP XML Templates for WS-Eventing messages, lists some SOAP XML Templates for WS-BaseNotification messages, and provides a summary of changes from the previous edition (ISO/IEC 24537:2006).
