You make a strong case for us having to respond to both SIF and IMS.
I am sure that many others are working to harmonize the SIF and IMS XML
As Steve T pointed out, SIF is more than just an XML schema: it is also
ZIS; like a telephone central hub which allows for secure communications
between SIF-compliant software using HTTPS and the protocol to transfer SIF
XML packets. (below I propose to make a napster-like ZIS)
Perhaps a few of us on this mailing list can experiment by transferring
XML Metadata between each other's applications so that we have something
concrete to show everyone else ... a picture (a live working system albeit
non-productive at this stage) is worth a thousand words.
Steve has his SIF Ack server, I have my zope server, Knut Y has a J2EE
if we assign a URL each using HTTPS such as:
which is a cgi form taking a made up student id such as "Doug Loss" and
spitting out some information about the fictitious courses he is taking at
each of these institutions, then anyone (with authentication privileges) can
compile a combined list of all the courses Doug Loss is taking at these
(let's say EDUML) compliant institutions
likewise another form with a keyword for subject such as "Math", could spit
out all the learning objects available marked as having subject "Math" in
their metadata ... and anyone can compile a list of all learning objects
about math from these 3 institutions
in fact, this has been called by a colleague, **learnster**, the napster of
education ... peer to peer sharing of resources and edu-administrative
We have a HUGE advantage over the commercial consortia (IMS, SIF) in that we
are not bogged down with commerical competitiveness consideration; so we
won't be spending too much time (I hope) worrying about making our learning
resources inaccessible to non-subscribers. But we do have PGP GPG and HTTPS
to protect stakeholders privacy.
Nonetheless, we will want to clearly (a la debian) mark the intellectual
property rights attached to each record... in fact that is already part of
metadata schemas right from Dublin Core and up.
