Chapter 4: Describing Data with SDDL: Your Data’s Blueprint

Welcome back, compression adventurers! In the previous chapters, we laid the groundwork for understanding what OpenZL is and why it’s a game-changer for structured data. We learned that OpenZL isn’t just another generic compressor; it’s a smart framework that wants to understand your data’s shape to compress it more effectively.

But how do we tell OpenZL about our data’s structure? That’s precisely what we’ll uncover in this chapter! We’ll dive into SDDL (Simple Data Description Language), OpenZL’s dedicated language for describing data schemas. Think of SDDL as the blueprint you provide to OpenZL, detailing every room, wall, and window of your data house.
