I'll summarise briefly some ideas that were floated with rlb over
e-mail a little while back. It was generally decided that we'd like
to get out:
* Sources (as per can be passed to fetch()).
* Whether a given source is guaranteed unique, or may have
failovers available for it.
* Human readable names for each source.
* The module(s) which implement each given source.
So the data structure we'd like to get out would look something like this:
{
asx =>
{ name => 'Australian Stock Exchange (failover)',
direct => 0,
modules => ['Finance::Quote::ASX',
'Finance::Quote::Yahoo::Australia']
}
asx_direct =>
{ name => 'Australian Stock Exchange (direct)',
direct => 1,
modules => ['Finance::Quote::ASX']
}
# etc etc
}
This means it's easy for us to find methods that will not be subject to
failover, can have nice human-readable names, and can tell easily who's
providing what methods.
Doing so will probably require a few changes to the Quotelet
(Finance::Quote:XXX) modules, and I'm going to have F::Q enforce
the direct attribute.
I'll discuss this a bit more on the F::Q development list shortly.
Short on time right now.
Cheers,
Paul
