Standardize Security Code

This project aims to provide an integrated link tables between ISIN and many other company/security identity codes.

Since many link tables are too large, please refer to this Dropbox folder.

Usage

The data format is Parquet. To read these files:

• In Python, you can use pandas.read_parquet (Doc).
• In R, you can follow Apache's official guidance.
• In MATLAB, see MathWork's guidance.
• In Stata, I have not tested the stata-parquet (GitHub). You can use Python to transform them into CSV format.

You can use URL to always read the most updated version of link tables:

import pandas as pd

df = pd.read_parquet('https://github.com/Wenzhi-Ding/Std_Security_Code/blob/main/isin/a4_orgid.pq?raw=true')
