Meme Paths (Data Flow Diagrams)

Trace one meme BUTNDIAM

We follow one FITS keyword BUTNDIAM through an imaginary control system.

Trace an entire bundle MOS_Catalog

An entire bundle (header) can be traced as one meme through our imaginary control system.

Trace one Agent "scrap"

What memes does the agent called "scrap" handle? If we changed it or it failed, what would be the effects?

MaskDesign bundle

Here we are sketching the information flow for manufacturing DEIMOS slitmasks.

Memes table

Here we show some of the tools that run against the Memes database, and their output. Where does Memes data come from, and what products does it turn into by means of what processes?

Sybase server

This is a trace of one agent, like "scrap" above, but the picture is very complicated even at this sketchy level because the database server sits in the middle of so many processes. This illustrates the need for context distinctions among meme paths.
