TP038 - Rules on payment instructions, SEPA direct debits, statements of account, partial statements and interest statements in paper and computerised form

ISO 20022-4:2013 was prepared to complement the ISO 20022 Metamodel, as specified in ISO 20022-1:2013, with the XML syntax transformation rules to be applied by the ISO 20022 Registration Authority in order to translate an ISO 20022 compliant MessageDefinition into an XML Schema for the description and validation of XML Messages. It specifies the transformation rules from level 3 to level 4. It is a deterministic transformation, meaning that the resulting XML Schema is completely predictable for a given MessageDefinition. There is neither manual input to the transformation itself nor manual adjustment to the result of the transformation.

ISO 20022-1:2013 consists of: the overall description of the modelling approach; the overall description of the ISO 20022 Repository contents; a high-level description of the input to be accepted by the Registration Authority to feed/modify the Repository's DataDictionary and BusinessProcessCatalogue; a high-level description of the Repository output to be made publicly available by the Registration Authority. BusinessTransactions and Message Sets complying with ISO 20022 can be used for electronic data interchange among any industry participants (financial and others), independently of any specific communication network. Network-dependent rules, such as message acknowledgement and message protection, are outside the scope of ISO 20022.

ISO 20022-2:2013 defines the UML Profile for ISO 20022. In essence, it defines how to use UML to create models that conform to the ISO 20022 Metamodel, which is defined in ISO 20022-1:2013. In so doing, it defines a UML-based concrete syntax for the Metamodel. It does not preclude the specification of additional concrete syntaxes for the Metamodel, such as a textual concrete syntax. The Profile defines how to represent in UML each of the Metamodel's Scope Level Elements (Level 1), Business Level Elements (Level 2) and Message Level Elements (Level 3), as well as Metamodel Elements that are scoped across the levels. Therefore, the Profile covers all of the Metamodel's Packages, except for the following: · ISO20022::Metamodel::ConceptualLevel::MessageTransport · ISO20022::Metamodel::LogicalLevel::Reversing · ISO20022::Metamodel::LogicalToPhysicalTransformation · ISO20022::Metamodel::PhysicalLevel The Profile also covers the ISO20022::TypeLibrary Package, upon which the Metamodel has some dependencies. ISO 20022-2:2013 is only applicable when UML is used.

ISO 20022-3:2013 describes the modelling workflow, complementing ISO 20022-1:2013 and ISO 20022-2:2013. The modelling workflow describes the required steps a modeller follows in order to develop and maintain standardized BusinessTransactions and MessageSets. ISO 20022-3:2013 is not intended to describe what will be the permissible artefacts and/or documents to be submitted to the Registration Authority (this information is contained in ISO 20022-7). Examples are provided only to illustrate the modelling methodology and are not normative.

ISO 20022-7:2013 specifies the responsibilities of the following bodies, which are involved in the registration and maintenance of the ISO 20022 Repository. The Registration Authority (RA) is the operating authority responsible for the registration and maintenance of the ISO 20022 Repository and for providing access to the information described in ISO 20022-1:2013. The RA is assisted by different Standards Evaluation Groups (SEG), i.e. groups of industry experts responsible for specific Business Areas of the Repository. A Technical Support Group (TSG) advises the SEGs, the RA, developers and communities of users on the technical implementation of ISO 20022. The Registration Management Group (RMG) is the governing body of the overall registration process and the appeal body for the communities of users, Submitting Organisations, the RA, the SEGs and the TSG. It monitors the registration process performance.

ISO 20022-8:2013 describes the transformation rules to generate ASN.1 abstract syntax from an ISO 20022 compliant MessageDefinition. The generated abstract syntax is for the description and validation of Messages. The transformation rules are a transformation from Level 3 to Level 4. It is a deterministic transformation, meaning that the resulting ASN.1 is completely predictable for a given MessageDefinition. There is neither manual input to the transformation itself nor manual adjustment to the result of the transformation. ISO 20022-8:2013 is the ASN.1 equivalent of ISO 20022-4:2013. In ISO 20022-4:2013 the abstract syntax generated is XML Schema; in ISO 20022-8:2013 it is ASN.1. In ISO 20022-4:2013 the only encoding supported is UTF-8 XML; in ISO 20022-8:2013 there are multiple encodings supported for ASN.1. These include all the standard encodings, but in addition the ability to register custom encodings in ECN.

ISO 20022-6:2013 specifies the characteristics of the MessageTransportSystem required for an ISO 20022 BusinessTransaction and MessageDefinition. Changes to the value of the MessageTransport Characteristics can affect the BusinessTransaction and MessageDefinition. Each BusinessTransaction in the ISO 20022 Repository is associated with a MessageTransportMode. The MessageTransportMode specifies the values for the MessageTransportCharacteristics.

ISO 11649:2009 specifies the elements of a structured creditor reference (RF Creditor Reference) used to facilitate the processing of data in data interchange and in the financial services, as well as between other business domains. The RF Creditor Reference is designed for use in an automated processing environment, but can also be implemented in other media interchanges (e.g. paper document exchange). ISO 11649:2009 does not specify internal procedures, file organization techniques, storage media, languages, etc. to be used in its implementation. It is applicable only to the textual data that can be conveyed through a system or network.

ISO/IEC 7064:2002 specifies a set of check character systems capable of protecting strings against errors which occur when people copy or key data. The strings may be of fixed or variable length and may have character sets which are numeric (10 digits: 0 to 9); alphabetic (26 letters: A to Z); alphanumeric (letters and digits). Embedded spaces and special characters are ignored. ISO/IEC 7064:2002 specifies conformance requirements for products described as generating check characters or checking strings using the systems given in this International Standard. ISO/IEC 7064:2002 is for use in information interchange between organizations; it is also strongly recommended as good practice for internal information systems. The check character systems specified in ISO/IEC 7064:2002 can detect: all single substitution errors (the substitution of a single character for another, for example 4234 for 1234); all or nearly all single (local) transposition errors (the transposition of two single characters, either adjacent or with one character between them, for example 12354 or 12543 for 12345); all or nearly all shift errors (shifts of the whole string to the left or right); a high proportion of double substitution errors (two separate single substitution errors in the same string, for example 7234587 for 1234567); a high proportion of all other errors. ISO/IEC 7064:2002 excludes systems designed specifically to: permit both error detection and automatic correction; detect deliberate falsification; check strings interchanged solely between machines. ISO/IEC 7064:2002 specifies two types of systems: pure systems; hybrid systems. The pure systems use a single modulus for all stages of the calculation.
