About MDDL
Market Data Definition Language (MDDL) is an XML-based interchange format and common data dictionary on the fields needed to describe 1) financial instruments, 2) corporate events affecting value and tradability and 3) market-related, economic and industrial indicators.
MDDL Mission Statement
The goal of Market Data Definition Language (MDDL) is to define a publicly available standard that provides a generic XML-based interchange format for the fields needed to describe financial instruments (including identifiers and current/historical values), corporate events (including specific corporate and instrument information affecting value and tradability), and market-related information (including economic and industrial indicators). The goal is to promote data interoperability.See more details on these pages:
