What Is Self-Describing Message?

Self-describing messages are basically like a sandwich made out of metadata. You have the bread, the schema that describes the structure of the entire message. And then you have the meat, the actual values corresponding to that schema. Self-describing messages are the best kind of messages. They're like many things. They're easy on the eyes, pretty straightforward, and make sense when you look at them. Unlike other items, self-describing messages have something to say! They tell you everything about themselves, who they are, what they're made of, and what they do. So if you've ever wondered what makes a self-describing message so special, keep reading; we'll tell you all about it! Messages are the best way to communicate between components of your system. It is a self-describing message that contains the data and metadata describing the format and meaning of a message. They usually have all the data needed to understand the message and all the information necessary to complete a task. The degree of dependency that exists between components across the system can be reduced with the help of self-describing messages, which also make it easier for client-server details to independently evolve. Those who are struggling to make sense of the world around them will find the message helpful because it describes itself. They're like reading a non-fiction novel that can fill you in on what's going on while you're reading it, and you don't even have to look up words in the dictionary to understand what they're talking about! Syntax and semantics might both be included in a message that describes itself. An Extensible Markup Language (XML) is an example of a self-describing message containing tags and value pairs. Essentially, self-describing messages contain both the metadata describing the message schema and the values that correspond to the schema.
