Thank you Thomas for your intrest

We have gone through the SOX proposal before and looked into several other solutions finding them not so general in the abstraction as we would like them to be to handle different use cases such as smart metering and business model spanning smart grid applications

The Andrew initiative is very good and can infact be more or less realised in our proposed solutions. The coming XEP's will show how to do provisioning and get access rights to field's on nodes. Which has similarities to your UUID_meta UUID_data JID proposals for accessrights but is more general.

Please let us elaborate more on the issues as we move forward

Hi Joachim,

Do these standards draw from or build upon the Sensors Over XMPP (SOX) proposal put forth by the Sensor Andrew team at CMU?

As noted we have posted 2 XEP proposals to the council.
http://xmpp.org/extensions/inbox/sensor-data.html
http://xmpp.org/extensions/inbox/exi.html

This is a serie of in total 11 XEP's that will be submitted shortly. Peter W and I Joachim L have been looking on earlier initiatives on using XMPP for sensor networks and specifically Internet Of Things.
We both have a long history in working with large scale sensor networks such as smart metering and energy efficiency systems. We are very aware that a lot can be created via the use of MUC,adhoccommands, pubsub, x-forms etc from other XEP's and we will adress this.

But what is very clear to us is that to create a solid infrastructure for interoperable sensor networks that will attract large companies, we need a set of XEP's that interact closely to cover the whole area from private proprietary networks up to the full internet of things open sensor networks. Therefor the XEP's are also namned together under XEP-0000-SN- exept for the EXI that is general.

The base is the SensorData just published and we are now working on the Provisioning, Control will come soon. EXI will enable us to implement this into very constrained networks. This will

XEP-0000-Exi Defines how to EXI can be used in XMPP to achieve efficient compression of data. Albeit not a sensor network specific XEP, this XEP should be considered in all sensor network implementations where memory and packet size is an issue.
xep-0000-SN-BatteryPoweredSensors Defines how to handle the peculiars related to battery powered devices, and other devices intermittantly available on the network.
xep-0000-SN-Concentrators Defines how to handle architectures containing concentrators or servers handling multiple sensors.
xep-0000-SN-Control Defines how to control actuators and other devices in sensor networks.
xep-0000-SN-Discovery Defines the peculiars of sensor discovery in sensor networks. Apart from discovering sensors by JID, it also defines how to discover sensors based on location, etc.
xep-0000-SN-Events Defines how sensors send events, how event subscription, hysteresis levels, etc., are configured.
xep-0000-SN-Interoperability Defines guidelines for how to achieve interoperability in sensor networks, publishing interoperability interfaces for different types of devices.
xep-0000-SN-Multicast Defines how sensor data can be multicast in efficient ways.
xep-0000-SN-Provisioning Defines how provisioning, the management of access privileges, etc., can be efficiently and easilly implemented.
xep-0000-SN-PubSub Defines how efficient publication of sensor data can be made in sensor networks.
xep-0000-SN-SensorData This specification. Provides the underlying architecture, basic operations and data structures for sensor data communication over XMPP networks. It includes a hardware abstraction model, removing any technical detail implemented in underlying technologies. This XEP is used by all other sensor network XEPs.

About Us

I am running a project iea.sust.se<http://iea.sust.se> in Sweden where we are looking on how to span sensor networks over the business model borders for companies. We have utility, energy service providers, domestic alarms, ventilation and heating systems working together to use XMPP as the infrastructure.
looking at large initiatives in eu such as fi-ware.eu<http://fi-ware.eu> we have identified the XMPP community as the best way to move forward.

Peter W has integrated numerous systems that the clayster.com<http://clayster.com> system supports and is now the main author of the XEP's

We are also active in the IEC/IEEE initiative where XMPP is to be used as infrastructure

Peter W had a presentation for the group
http://www.slideshare.net/peterwaher/xsf
The group is now looking also looking on these extensions

Anyone willing to participate in this work are eagerly encouraged to contact us bilaterally or through the mail groups.
