Concepts

Five short pages covering the cross-cutting ideas that apply to every LABO data stream. Read them in order if you're new to LABO data; jump to a specific page if you have a specific question.

Page	What it covers	Read it when
Regular vs irregular	The two stream families and how to tell which one fits your question.	First. Everything else assumes this framework.
Timing	Three clocks, MonotonicExecutionTime, when each row is stamped, display offset.	Second. Anchors all temporal analysis.
Join keys	Which columns to use to align rows across CSVs.	When you're combining two streams.
Column conventions	The shared prefix, coordinate system, units, placeholders, value encoding.	Reference; dip in as needed.
File layout	Where CSVs land on disk, naming patterns, gating rules.	When a file you expected isn't there, or you're scripting bulk loads.

These pages link into each other and into the per-stream pages. If you only ever read two of them, read Regular vs irregular and Timing.
