BLUE – Metadata—parts or the whole of
information packages and descriptive information. On the well-known,
high-level OAIS diagram, they appear in little ovals.
GRAY – Internal computer
messages—not meant for human consumption
Next we’ll hear from Markus Enders from Gottingen who will talk about metadata,

PINK – Human-readable policies and
reports.
When I look at this diagram, with the messages highlighted this way, I start
to understand that the functions are information processing functions. They modify
the messages they receive and send them on—ultimately to storage or to the
human actors identified in the high level OIAS diagram: the Management, the
Producer, or the Consumer.
