The DTCCCARESD1 message extends ISO corporate action movement reversal advice message with DTCC corporate action elements not covered in the standard message.
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
classDiagram direction LR %% DTCCCARESD1V03 recursion level 0 with max 0 DTCCCARESD1V03 *-- "0..1" CorporateActionGeneralInformationSD35 : CorporateActionGeneralInformation DTCCCARESD1V03 *-- "0..1" FinancialInstrumentAttributesSD20 : UnderlyingSecurity
Now, we will zero-in one-by-one on each of these building blocks.
CorporateActionGeneralInformation building block
Information to be extended as supplementary data to corporate action general information. Provides additional information regarding corporate action general information. For comparison, see the ISO20022 official specification
classDiagram direction tb %% CorporateActionGeneralInformationSD35 recursion level 0 with max 1 class CorporateActionGeneralInformationSD35{ PlaceAndName IsoMax350Text EventGroup EventGroup3Code EventType ExtendedEventType6Code SubEventType DTCCSubEventType6Code }
CorporateActionGeneralInformationSD35 members
Member name | Description | Data Type / Multiplicity |
---|---|---|
PlaceAndName | Xpath to the element that is being extended. | IsoMax350Text - Optional 0..1 |
EventGroup | DTC processing domain/ category for event types. | EventGroup3Code - Optional 0..1 |
EventType | DTCC (The Depository Trust and Clearing Corporation) native corporate action event type name. Used in place for the events that cannot be classified by ISO code and mapped to OTHR or when two or more distinct events (in DTCC model) use same ISO code and there are no additional data elements that distinguish those two or more events. | ExtendedEventType6Code - Optional 0..1 |
SubEventType | DTCC (The Depository Trust and Clearing Corporation) native corporate action sub event type name further defines the event type. | DTCCSubEventType6Code - Optional 0..1 |
UnderlyingSecurity building block
Information to be extended as supplementary data to underlying security details. Provides additional information regarding underlying security details. For comparison, see the ISO20022 official specification
classDiagram direction tb %% FinancialInstrumentAttributesSD20 recursion level 0 with max 1 class FinancialInstrumentAttributesSD20{ PlaceAndName IsoMax350Text MoneyMarketInstrumentFlag IsoYesNoIndicator }
FinancialInstrumentAttributesSD20 members
Member name | Description | Data Type / Multiplicity |
---|---|---|
PlaceAndName | Xpath to the element that is being extended. | IsoMax350Text - Optional 0..1 |
MoneyMarketInstrumentFlag | Indicates that the underlying security is a money market instrument. | IsoYesNoIndicator - Optional 0..1 |
Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the DTCCCARESD1V03 implementation follows a specific implementaiton pattern. First of all, DTCCCARESD1V03 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCARESD1V03Document implements IOuterDocument. Because DTCCCARESD1V03 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCARESD1V03.
classDiagram class IOuterRecord DTCCCARESD1V03 --|> IOuterRecord : Implements DTCCCARESD1V03Document --|> IOuterDocument~DTCCCARESD1V03~ : Implements class IOuterDocument~DTCCCARESD1V03~ { DTCCCARESD1V03 Message }
Document wrapper for serialization
The only real purpose DTCCCARESD1V03Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.025.001.03’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCARESD1V03.ToDocument() method. The returned DTCCCARESD1V03Document value will serialize correctly according to ISO 20022 standards.
