perfsonar development work

[Charaka Palansuriya <>]

Hi Loukik, Nicola and Nina,

Thank you for your prompt replies.

What Kostas, Jeremy and I were trying find out is the difference between 
the "nmwg v2.2-netutil" schema and the "nmwg v2.2" schema. Few months ago, 
I read the NMWG Schema Developers Guide ( 
http://stout.pc.cis.udel.edu/NMWG/devguide.pdf) which describes how to use 
the NMWG base schema. If my memory is correct, the NMWG Schema Developers 
Guide describes a base NMWG (v2.2 ?) schema which can be extended for 
particular use with its own namespace (this would explain the usage of the 
"netutil namespace" that you mentioned in your emails:). Therefore more 
specific questions would be,

 1) How does the "nmwg v2.2-netutil" schema extends the base schema ?
    I.e., does it define its own elements and attributes ? For example,
    do you replace definition of elements in nmwg:metadata and nmwg:data
    present in the base schema.

 2) Does "nmwg v2.2-netutil" schema restrict and/or ignore usage of any
    elements in the base schema (e.g., optional commonTime element) ?

Hope these are much more clearer question. Please let me know if you 
require any further clarification.

If there are more suitable documents that I should have a look at please 
feel free to point them to me.

Cheers,
Charaka
