    66== 1)  Goals ==
    77
    8  Assume that Lookup Service will be implemented by GEMINI project using UNIS service.  [[BR]]
     8 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.
    99
    10  The Lookup Service will
     10 In addition, a similar Topology Service is used to store the topology of the network being examined. 
     11
     12 Together, these services are combined in the Unified Network Information Service (UNIS). 
     13
     14 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]]
     15
     16 For GENI, the Measurement Information service (MI) will be provided to serve the need for a global UNIS service.
     17
     18 Can the MI service be used for other registry functions?
     19
     20 Can the MI service be used for finding web interfaces, and other types of portals?
     21
     22 Can the MI service be used to provide topology information to assist resource assignment and stitching in GENI? 
    1123
    1224==  2)  Tasks ==
    1325
    14  For a detailed list, see the Spiral 4 SOW of the GEMINI project; these include:  [[BR]]
    15 c)      Refactor UNIS (combined Lookup and Topology Services) to support hierarchical operation with local and global instances:
    16 1.      Update topology model to Rspec version 3 and AM API (February 2012)
     26 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]]
     27
     281)      Refactor UNIS (combined Lookup and Topology Services) to support hierarchical operation with local and global instances:
     292)      Update topology model to Rspec version 3 and AM API (February 2012)
    17302.      Modifications to allow local UNIS to register with global UNIS (March 2012)
    18313.      Initial deployment of persistent GENI Global I&M Registry (GGR) service, based on UNIS. (May 2012)
     
    20335.      Unify Perl and Python implementations (September 2012)
    2134
    22  Define, prototype, demonstrate and operate a GENI Lookup service, starting at GEC12. [[BR]]
     35 Define, prototype, demonstrate and operate a MI service, starting at GEC12. [[BR]]
