perfsonar development work

[Yee-Ting Li <>]

Hi all,

thanks for the quick response! i think i have plenty to study for now ;)

i've noticed that the wiki is 'littered' with very old spec xml  
files, and i found it rather confusing as none of them seemed to work!

are there higher level documents describing the overall structure/ 
method of the xml files? ie like lists of message types, event types  
to use etc?

Nina: yes, i was playing around with perfsonarui and i found the  
playground very useful :) in as much as none of the examples on the  
wiki worked! ;)

many thanks,

Yee.
