Technical Summary
This memo describes a detailed framework for composing and
aggregating metrics (both in time and in space) originally defined
by the IP Performance Metrics (IPPM) RFC 2330 and developed by
the IETF. This new framework memo describes the generic composition
and aggregation mechanisms. The memo provides a basis for
additional documents that implement the framework to define
detailed compositions and aggregations of metrics which are
useful in practice. 

Working Group Summary
The normal WG process was followed and the document has been discussed for
several years. The document as it is now, reflects WG consensus, with
special worth noticing.
Protocol Quality
This is a framework document, implementations for specific situations
(spatial, temporal, etc) will be discussed in future documents.
