=head1 DESCRIPTION

This class manages asset sources. A source is an organization that provides
content, such as a wire service or a syndicate. Thus, each source object is a
kind of organization, and inherits all of an relevant data accessors, including
those for addresses.

This class adds three basic data points to the organization: A description, an
expire, and an active flag. The description is a simple free-text
description of the source. The expire property is a simple integer
representing the number of days an asset provided by a given source may be used
before it must be removed as content. The active flag is just like any other
active flag, except that it is separate from the Bric::Biz::Org active flag. Thus a
Bric::Biz::Org::Source object may be deactivated while its parent Bric::Biz::Org
object remains active.

Returns an anonymous hash of introspection data for this object. If called
with a true argument, it will return an ordered list or anonymous array of
introspection data. If a second true argument is passed instead of a first,
then a list or anonymous array of introspection data will be returned for

assumed).

Each hash key is the name of a property or attribute of the object. The value
for a hash key is another anonymous hash containing the following keys:

attribute.

=item set_args

An anonymous array of arguments to pass to a call to set_meth in order to set
the value of the property or attribute.

types:

=over 4

=item short

=item date

=item blob

=back

=item len

If the value is a 'short' value, this hash key contains the length of the
field.

=item search

=item req

The property or attribute is required.

=item props

An anonymous hash of properties used to display the property or
attribute. Possible keys include:

=over 4

the change persistent.

=item my (@gids || $gids_aref) = $u->get_grp_ids

=item my (@gids || $gids_aref) = Bric::Biz::Person::User->get_grp_ids

Returns a list or anonymous array of Bric::Biz::Group object ids representing the
groups of which this Bric::Biz::Org::Source object is a member.

B<Throws:> See Bric::Util::Grp::list().

B<Side Effects:> NONE.

B<Notes:> This method returns the group IDs for the current object both as a
Bric::Biz::Org object and as a Bric::Biz::Org::Source object. [Actually, I've
commented this out for now, since it seems more likely at this point that we'll
want only the source group IDs, not also the organization IDs. We can uncomment
this later if we decide we need it, though.]
