The org table is used for the "org:" attribute, which can appear in any
object.

The organisation and org_name tables are for the respective attributes,
which appear in the organisation objects.

The organisation_id table is used for the auto-generated "organisation:"
attributes. We base the attribute on the first letters of the
organisation name, plus a number. So "Shane's ISP" would have
"ORG-SI###-RIPE" as the "organisation:" attribute. The number, ###, is
determined by looking at the organisation_id table. So the code does
something like:

SELECT range_end+1 FROM organisation_id WHERE space="SI" AND source="-RIPE";

The source column is the same as the "source:" of the database: RIPE for
us, AFRINIC for you.
