Yes, this is what most of the other comments aren't emphasizing—resource forks had a standardized format and Apple even shipped a tool for visualizing/editing them. They were also extended so you could tag and embed any arbitrary data you wanted to. This was fantastic because it allowed me as a young programmer to poke around in real shipping products and see how they organized things. The same way you might poke around inside an .app wrapper or a .xib file nowadays. But 30 years ago!

From today's perspective, they are just there for backwards compatibility.
