perfsonar development work

[Jochen Reinwand <>]

Hi,

Our perfSONAR services (Hades MA and BWCTL MP) are written in Perl. We did 
not 
try to make something similar to the Java implementation, since we decided to 
do it "the Perl way". We used mainly XML::LibXML for XML handling and 
SOAP::Lite for the SOAP stuff. But the later one will be replaced by directly 
using HTTP modules, because SOAP::Lite is (at the moment) not the right 
module for perfSONAR.
Our code was made having some sort of perfSONAR Perl module in mind, but 
since 
our services are by now the only services using Perl, we haven't put much 
effort into really supplying such a module. We also do not have a really 
fixed API, since we always have to implement new feature, that need to be 
compatible with the Java stuff. But since a few things have to be added and 
reworked we might put some more work in this module in the next few weeks...

You can find our code in the Subversion repository here: 
http://tod.rrze.uni-erlangen.de/hades/trunk/

http://tod.rrze.uni-erlangen.de/hades/trunk/framework/bin/perfsonar.pl
is our daemon providing all perfSONAR services. It uses modules in 
http://tod.rrze.uni-erlangen.de/hades/trunk/framework/lib/

I hope this helps you a little with your decision...
BTW: What exactly are you planning to do? Implementing a new service in Perl?

regards,
Jochen
