     2361)  Goals  [[BR]]
     237
     238 A Lookup Service is a type of registry defined in the perfSONAR toolset;  the availability of MD at perfSONAR interfaces MC services is registered there, using metadata describing the data and its location.
     239
     240 In addition, a similar Topology Service is used to store the topology of the network being examined. 
     241
     242 Together, these services are combined in the Unified Network Information Service (UNIS). 
     243
     244 The GEMINI project includes perfSONAR tools, and requires UNIS functions.  Some will be provided locally (within the slice), but a global service is required if available MD is to be registered, so that users can find it and get it.  [[BR]]
     245
     246 For GENI, the Measurement Information service (MI) will be provided to serve the need for a global UNIS service.
     247
     248 Can the MI service be used for other registry functions?
     249
     250 Can the MI service be used for finding web interfaces, and other types of portals?
     251
     252 Can the MI service be used to provide topology information to assist resource assignment and stitching in GENI? 
     253
     2542)  Tasks  [[BR]]
     255
     256 The MI service will be built by the GEMINI project using UNIS technology;  see the Spiral 4 SOW of the GEMINI project for the detailed steps, which include:  [[BR]]
     257
     2581)      Refactor UNIS (combined Lookup and Topology Services) to support hierarchical operation with local and global instances: [[BR]]
     2592)      Update topology model to Rspec version 3 and AM API (February 2012) [[BR]]
     2602.      Modifications to allow local UNIS to register with global UNIS (March 2012) [[BR]]
     2613.      Initial deployment of persistent GENI Global I&M Registry (GGR) service, based on UNIS. (May 2012) [[BR]]
     2624.      Complete noSQL (MongoDB) backend (September 2012)  [[BR]]
     2635.      Unify Perl and Python implementations (September 2012) [[BR]]
     264
     265 Define, prototype, demonstrate and operate a MI service, starting at GEC12. [[BR]]
     266
     267 Support use in GENI by many tools, including  GEMINI and GIMI I&M tools  [[BR]]
     268
     269 Define operations plan for MI service.  [[BR]]
