Yes. That could work.  And we already have (in perl) a recommended way
to say what we want to import from a module.   But most modules uses
an OO interface.  You should do something like:

my $obj =3D new http://www.uxn.nu/rpm/Math/Complex.pm;


But I'm sure that the Perl6 stuff will be good.

It depends on if you are stating the implementation or the function
you want to use.  And maby there is someone else who wants to import
the module.  The users choise has to be approved by the sysadmin.

I'm mainly thinking about connections to other RDF services.  And that
all Wraf interfaces should be extendable and upgradable through Wraf
itself.

The embedded version numbers in the interface module names is a step
on the they to eventually store the interface inside Wraf.

        RDF::Service::Interface::DBI::V01

He. Another moment 22.  How do I connect to the DBI interface if it's
stored in the DBI interface? :-)


and this will have two types of interfaces.  The local interfaces that
transparently gets downloaded and installed.  And the remote
interfaces that use another Service on another server.


The SOAP thing would be just like having an interface to retrieve
resource properties.  Nothing complicated here...

Yes. :-)

And to get the second first name you had in 1980:

[% person.fn( date =3D 1980 ).li(2).value %]


But that's not implemented yet...






 RDFS:label

Now I must continue hacking.  I have a stupid resource that doen't
want to be saved.  It should be because i have put a label on it, and
that label should be preserved...

labels being one of the special cases.  Maby it shouldn't be a special
case.  Probably shouldn't...  But it forces me to sort out entrypoints
for implicit properties. And that will be used by infered properties.
So this is sort of a small step toward that.
