mifir-concat

Derive MiFIR CONCAT identifiers in accordance with EC 2017/590 article 6 and the ESMA guidelines for transaction reporting. The package exposes a reusable CreateConcat helper while the CLI streams input from stdin so it can be composed in shell pipelines.

Features

• Deterministic CONCAT derivation aligned with ESMA guideline test cases
• Prefix and title stripping based on the MiFIR specification
• Unicode character folding to the expected Latin alphabet
• Throughput-oriented implementation; single-core benchmarks exceed 100k CONCAT/s

Installation

go install github.com/robfordww/mifir-concat@latest

Building and Testing

Clone the repository locally when you need to develop or run the legacy benchmarks.

git clone https://github.com/robfordww/mifir-concat.git
cd mifir-concat
go test ./...
go build

Command-Line Usage

Pipe MiFIR person records to stdin using the pipe-delimited format ISOCOUNTRYCODE|YYYYMMDD|FIRSTNAME|LASTNAME:

./mifirconcat < persons.txt

Example:

AT|18870812|Erwin|Schrödinger

Output:

AT18870812ERWINSCHRO

Library Usage

concat, err := CreateConcat("AT", "18870812", "Erwin", "Schrödinger")
if err != nil {
    log.Fatal(err)
}
fmt.Println(concat)
