perfsonar development work

["Murilo Vetter" <>]

Hi Freek,

I was following your messages about NMWG implementations. If it is 
interesting to you, we implemented the NMWG protocol in PHP. It is similar to 
pS version which parser the messages and creates an object so you can handle 
the NMWG messages in a higher approach.

We are using it to our services in RNP - Brazil. Tell me if it is interesting 
to you so we can provide an access to the source.

Cheers,
Murilo Vetter

Assunto: Re: [pS-dev] PerfSONAR WSDL

Hi Jason,

Thanks for the pointers. Indeed there are a bunch of WSDL files in the MDM 
subversion repository, including those for E2Emon. Roman pointed me off-list 
to them as well (thanks, Roman!).

Unfortunately, while the message types are described, the message content is 
not -- only the top level nmwg:message tag is described, not the nmwg:data or 
nwmg:metadata tags, let alone the really interesting tags and attributes. 
This means that even with a WSDL, one has to do a lot of validation 
themselves, so it only helps me a little bit.

I was trying to understand if it is possible to extend the WSDL or if NMWG is 
so flexible that this never gains anything useful. It indeed seems easier to 
simply parse the XML myself -- like pS-PS and Sander's code do.

Sander told me the same, but the difference is only sketchy to me yet.
This comments helps me, thanks!

Yup :)

Thanks,
