[Fiware-iot] [FI-WARE IoT] NGSI considerations

[Guerra Sabrina]

Hi Fermin,

Thanks for your prompt answer.
The next step could be to evaluate your NGSI considerations in the interaction between the Data Handling and the Protocol Adapter GEs.

Best regards,
Sabrina

Oggetto: Re: [Fiware-iot] [FI-WARE IoT] google doc updated and NGSI considerations

Dear Sabrina,

"I don't know if the actuation is comprised in the NSGI specification."

Probably this question fits better in NGSI mailing list, but I do confirm that NGSI have "build-in" actuation mechanisms.

However, there is a easy workaround: consider updates with side-effects. E.g. you can define an attribute e.g. "executeCommand" on a given entity, so when you do an updateContext on that "executeCommand" then a command is executed (the value used on the update for that attribute is the command to execute). If you need to capture a result for the command, you can have another attribute (eg. "executeCommandOutput") so when the command is finished, you will get the output in the attribute.

I'm not sure but old good SNMP has a similar approach to execute commands in managed devices.

My two cents...

Best regards,

Hi Thierry and Carlos,

As we agreed in the conf call I updated the minutes at the following link.

https://docs.google.com/document/d/15rp8NKsCvu9Q4ISXwXl2iHc8cXz3DaNyBhVLq3qhgj8/edit

In this google doc you can see these topics:

*         the feedbacks from the UC projects related to the webinars

*         a comment about the status of the implementation of the NGSI interface in the Protocol Adapter.

By the way there is another point that is not clear about the NGSI interface: the interface between the Data Handling GE and the Protocol Adapter GE doesn't define an actuation command. Currently this operation is only available using the TI servlet  that is based on the GDA API (by Ericsson). I don't know if the actuation is comprised in the NSGI specification.

Best regards,
Sabrina
