Hughes-Jones Manchester 8 Schemata: History  NM-WG then focused on standardizing schemas for exchanging network measurements  Extended concept to Requesting historical network measurements Requesting measurements to be made on demand Traps and Event Notification  NM-WG has Two sets of schemata: v.1::Monolithic, straight mapping of “characteristics” doc v.2::Framework: Base schema - common components, types, topology Add separate sub-schema for each characteristic and/or tool Framework has extensibility to just about anything Schema language: Relax-NG compact syntax

To the schemata: Corrections Additions For the Recommendation document itself: What form should the document take? Do we explicitly include the Base Schemata? What about common example schemata rtt/ping achievable throughput/ping … Definition of the Namespaces, nmwg probably yes what about the others we currently use?  How dependent is the Recommendation document on Relax NG?
