CorporateActionNarrativeV03

seev.038.001.03

Scope The CorporateActionNarrative message is sent between an account servicer and an account owner or its designated agent to cater for tax reclaims, restrictions, documentation requirements. This message is bi-directional. Usage The message may also be used to:

Message Construction

Every ISO20022 message has at the highest level what we call ‘building blocks’. Because the message is constructed as immutable records, the association is by composition. Below you can see the relationship between the message and its constituent building blocks: For comparison, see the ISO20022 official specification

     direction LR
%% CorporateActionNarrativeV03 recursion level 0 with max 0

ISIN International Securities Identification Number (ISIN). A numbering system designed by the United Nation’s International Organisation for Standardisation (ISO). The ISIN is composed of a 2-character prefix representing the country of issue, followed by the national security number (if one exists), and a check digit. Each country has a national numbering agency that assigns ISIN numbers for securities in that country. IsoISINIdentifier - Optional 0..1

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the CorporateActionNarrativeV03 implementation follows a specific implementaiton pattern. First of all, CorporateActionNarrativeV03 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, CorporateActionNarrativeV03Document implements IOuterDocument. Because CorporateActionNarrativeV03 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type CorporateActionNarrativeV03.

classDiagram
    class IOuterRecord
    CorporateActionNarrativeV03 --|> IOuterRecord : Implements
    CorporateActionNarrativeV03Document --|> IOuterDocument~CorporateActionNarrativeV03~ : Implements
    class IOuterDocument~CorporateActionNarrativeV03~ {
        CorporateActionNarrativeV03 Message
     }

Document wrapper for serialization

The only real purpose CorporateActionNarrativeV03Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:seev.038.001.03’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using CorporateActionNarrativeV03.ToDocument() method. The returned CorporateActionNarrativeV03Document value will serialize correctly according to ISO 20022 standards.
