NM-WG V2 Schemas Discussion (1 of 2)

• Issues in arbitrary order
• Normalisation (Jeff)
• If were returning a lot of data all with same
  time stamp, we don't want the include the same
  timestamp repeated for each piece of data.
• We want to be able to pull out a certain piece of
  data (timestamp is just an example, theres
  probably more) and refer to it just once.
• Versioning.can it be done using the namespace,
  e.g. http//ggf.org/ns/0.0.1/nmwg/? (Martin)
• GridFTP (Mark) - can V2 schemas be produced to
  express GridFTP logs? src, dest, file size, time
  taken
• Bag of generic parameters for message and store
  (Martin)
