+Discussion topics:
+Are these five services a complete group of I&M services?  
+
+Are these good names for the five I&M services?
+
+Is this five the right granularity for I&M services?
+
+Is this a complete and flexible configuration for I&M services?
+
+Can this configuration accommodate the range from small-scale to large-scale implementations?
+
+How can we obtain a consensus, so that we can set a firm foundation for the other topics?
+
+Interfaces, protocols and schema for measurement data:
+
+Issues:
+This topic suggested at GEC6 meeting:  Common schema for MD
+Can we identify a common set of interfaces, protocols and schema for MD, or at least a limited number of types?
+What needs to be included in the MD schema?
+
+Approach:
+Assume all MD after MPs follows this common set of interfaces, protocols and schema
+Start with definition of MD schema
+Next, understand  [8.  MD Transport via GENI Measurement Plane]
+Then, complete first set of interfaces and protocols
+
+From GENI I&M Capabilities Catalog (v0.1), these GENI projects (and others) are working on data schema and/or data archives:
+
+perfSONAR for network measurements   (Swany, Univ Delaware, 1788)
+IMF project  (Dutta, NC State, 1718)
+Embedded Real-Time Measurements  (Bergman, Columbia, 1631)
+GENI Meta-Operations Center  (Herron, Indiana Univ, 1604)
+netKarma:  GENI Provenance Registry  (Pale and Small, Indiana Univ, 1706)
+DatCat project at http://www.datcat.org/   (Klaffy, CAIDA)
+Crawdad project at http://crawdad.cs.dartmouth.edu/  (Kotz, Dartmouth)
+Amazon Simple Storage Service
+Data-Intensive Cloud Control   (Zink and Cecchet, UMass Amherst, 1709    )
+Experiment Mgmt System (Lannom and Manepalli, CNRI, 1663)
+others?
+
+What can we learn from these projects?
+
+Discussion topics:
+
+Standardized interfaces between measurement services
+Pt-to-pt vs pt-to-multipoint (e.g., pub/sub)
+Stream vs bulk transfer
+Disconnection operation expected, or not.
+
+Protocols for moving measurement data
+Streaming data
+Bulk-transfer of data
+
+Schema for measurement data
+Data record identifier
+Annotation, or meta data
+Data types and values, with timestamps
+
+How can we obtain a consensus on first set of intfc’s/protocols/schema for MD?
+
+What is the process for extending the set?
+
+
+GENI measurement plane:
+
+Issue:
+Need to understand how MD traffic flows are transported  by the GENI Measurement Plane before the interfaces and protocols for MD can be fully defined
+
+Approach:
+Understand current view of GENI Control Plane and Experiment Plane
+Consider options for GENI Measurement Plane to transport MD flows, using networks that implement GENI Control and Experiment Planes
