[Fiware-iot] Status of UniSurrey ConfMan GEI wrt NGSI-9

[t.elsaleh at surrey.ac.uk]

Hello Thierry, All,

I would like to clarify the status of the GEI from UniSurrey, i.e. IoTDiscovery

Our current implementation has focused on the features defined in the technical roadmap for ConfMan GE that are based on semantic descriptions as this was our original planned contribution to FIWARE. And since there are no GEs in the IoT chapter that are involved in this, then from this perspective our current implementation is more or less a standalone enabler for any user who wants to register and discover IoT-A based semantic descriptions. There are other semantic-oriented enablers from the Data chapter, but I do not believe we are at the stage of integration with them at the moment.
The reason why we focused on the features that were not related to NGSI was that I understood that the all the features declared had to be collectively covered by the GEIs, meaning that if one GEI does one set of features, the other has to cover at least the remaining features.

With respect to NGSI-9 support, the currently supported bindings for our GEI are the following Convenience Operations:

* POST - //{serverRoot}/NGSI9/contextEntities/{EntityID}
* GET - //{serverRoot}/NGSI9/contextEntities/{EntityID}
* GET - //{serverRoot}/NGSI9/contextEntities/{EntityID}/attributes
* GET -  //{serverRoot}/NGSI9/contextEntities/{EntityID}/attributes/attributeName
* GET -  //{serverRoot}/NGSI9/contextEntities/{EntityID}/attributeDomains/{attributeDomainName}
* GET -  //{serverRoot}/NGSI9/contextEntityTypes/{typeName}

Updating registrations and specific discovery request restrictions like <operationScope> and <Association> have not yet been implemented, but are planned for R3.

In comparison to TID implementation, according to this spreadsheet<https://docs.google.com/spreadsheet/ccc?key=0Aj_S9VF3rt5DdEhqZHlBaGVURmhZRDY3aDRBdlpHS3c#gid=0>, their implementation supports (with updating, scope and associations):

GET    /ngsi9/contextEntities/{EntityId}
POST   /ngsi9/contextEntities/{EntityId}
GET    /ngsi9/contextEntities/{EntityId}/attributes
POST   /ngsi9/contextEntities/{EntityId}/attributes
GET    /ngsi9/contextEntities/{EntityId}/attributes/{attributeName}
POST   /ngsi9/contextEntities/{EntityId}/attributes/{attributeName}

Based on this I will liaise with NEC, to see how we can go about testing, despite the missing features.

Best regards,
Tarek
