Only just spotted this - but I agree with you Didier. I've actually
implemented a system using Microsoft's LDAP server to store XML nodes
and RDF nodes. I'm not yet on Win2000 so I don't know if the performance
will improve when I switch (and also use SQL 7), but at the moment it is
not too good. However, the advantages of the ease with which I can
change the meta data coupled with the resilience of LDAP have made me
stick with it.
 
I think the next piece of the jigsaw is the interface. I have
written (or shall we say - am still writing!) a WebDAV layer over the
LDAP. So far I can browse my XML with Microsoft's WebFolder client, and
upload NITF documents which get broken into XML nodes, and then have
loads of RDF added to them.
 
Regards,
 
Mark

Hi,
 
Did we mentionned directory services to store RDF?
In fact, directory services like for instance, LDAP are a perfect match
with RDF. 
a) they are hierarchical (useful but not necessary for RDF)
b) they are frame based (very useful and necessary for RDF)
c) they support frame typing (very useful for RDF and a plus because we
have here the occasion to apply concretely RDF shemas)
d) they already or will in a very near future contain the enterprise
meta data for devices, users, organization units, etc...
e) they are or will be part of operating systems (Solaris, Win2000,
Linux, etc...)
 
So, in my own opinion, directory services like for instance LDAP servers
are a very good match for storing RDF. Going further on this, don't you
think that RDF is a perfect candidate for directory data serialization.
 
Cheers
Didier PH Martin
