Query properties via HTTP GET

Hello,


I've been using WSRF::Lite (in perl) for a while, and
there's a feature 
that I find quite useful for debugging: it's possible to
get all the 
properties by pointing a web browser (or wget, etc.) to the
EPR address 
(WSRF::Lite include the resource identifier in the EPR
address).


In effect, it gives the same result as the content of the
response to a 
query like this:

<wsrp:QueryResourceProperties 
xmlns:wsrp="http://docs.oasis-open.org/ws
rf/2004/06/wsrf-WS-ResourceProperties-1.2-draft-01.xsd&
quot;>
<wsrp:QueryExpression 
Dialect="http://w
ww.w3.org/TR/1999/REC-xpath-19991116">*</wsr
p:QueryExpression>
</wsrp:QueryResourceProperties>



Is there a way to achieve something similar with Apache
WSRF? For 
example by querying something like this:
http://localhost:8080/wsrf/services/filesystem
?ref=/dev/vg00/lvol1

How hard would it be to implement? (Additionally, how hard
would it be 
to adapt Apache WSRF so that it can use EPRs without
resource identifier 
but with just an address of that form?)



Regards,


Bruno.

Well anything is possible....

But not all services implement Query, so then it becomes an
issue of 
does the service implement query?  if so do this, else do
that....

If you'd like to take a crack at implementing it, then I'm
all for it
