Has anyone looked into adding XMPP support to the open-source meshblu
framework?
https://developer.octoblu.com/
I met the Octoblu folks recently and they were enthusiastic about adding
XMPP support (well, about having someone else add it).

Hi,
I was wondering if (parts) of the IoT XMPP specifications and / or components that are used within the specification are already implemented as open source or otherwise?
I'm particularly interested if there is some sort of a reference implementation of a "Thing Register".
Best regards,
Eelco

Hi,
I'm currently investigating options to implement something similar as the IoT registry that is described in XEP-0347 but I have some different requirements that I would like to share as they might help to improve this XEP.
I would like to allowing more complex searches in the registry. For example I would like to be able to do spatial searches:
- give me 10 temperature sensors closest to a given location.
- give me all light-switches in a range of hundred meters around a given location.
Following the current XEP I cannot ask such queries directly but should fire multiple queries and do all calculation in the client.
Also I would like to do union searches so I do not have to calculate intersections myself:
- give me all light-switches or light-dimmers closest to a given location.
As these type of queries are more complex and not all registry servers might have implemented such a feature I would like to add the possibility to discover registry capabilities. This kind of discovery can be done using entity capability (XEP-0115).
Also the current description XEP-0347 allows only meta-data that consist of numbers and strings but I would like to be able to have more options (including location). Maybe we can reuse the stuff that is in XEP-0004 data-forms (https://xmpp.org/extensions/xep-0004.html#protocol-fieldtypes) and add XEP-0350 (data forms geolocation element).
This would allow more semantical reasoning on the meta-data of a thing (like the example queries above).
What do you think?
Best regards,
Eelco
