I've had my head down in dbnomics stuff lately (informative
posting to
come before long), but I noticed in passing some comments/queries
about series in bundles. I'm afraid I've lost the references but I'll
post on the topic in general.
Perhaps one of those comments was my post from June 29th.
The thing to remember is that bundles are just a transport mechanism
for series. You can't "really" have a series in a bundle, since series
belong to datasets and bundles know absolutely nothing about datasets;
you can only have the ghost of a series.
A "series" in a bundle has a status akin to a soul being rowed across
the Styx by Charon, with the difference that it is possible to regain
the living side under the right circumstances (the ghost-series is
extracted into a conformable dataset).
Very nice metaphor! I wonder how this whole affair should be
communicated to script writers. Maybe it should be pointer-to-series
instead of series in a bundle then?
How is the "ghost" actually kept in the bundle? By ID number, and if so,
what happens upon renumbering? Or by name?
thanks,
