The Smart Object Framework is a reference implementation of the Smart Model API described at:

http://iot-datamodels.blogspot.com

Currently a copy of the RDFlib is in SmartObjectFramework/ObjectService/rdflib

This will later be made into an external dependency. Original source: https://github.com/RDFLib/rdflib

https://code.google.com/p/restlite/

Currently this is a heavily modified version in order to support the authentication model used in the SmartObject resource model. It is in

SmartObjectFramework/ObjectService/restlite

We may later switch this out for another Rest interface library that we can use as an external dependency

The root of the code is in SmartObjectFramework/ObjectService

ObjectService is a SmartObject instance which is used to store a Description for the service and a number of SmartObject instances

GatewayObjectService is an ObjectService with two service interfaces, for example one interface for a constrained network e.g. a sensor net using CoAP, and another interface for the internet using http.

The interface classes add URL-resource mapping, and content-type negotiation and generation by invoking parse and serialize methods from the specific resource classes.

Only tested with Python 2.7.x

Ideally use python virtualenv and virtualenvwrapper to create an isolated python evnironment but this is not required.

cd to some place you want to download the Smart Object Framework

git clone git@github.com:OSIOT/IoT-Toolkit.git
cd SmartObjectFramework/ObjectService
pip install -r requirements.txt  # This installs any python dependency libraries
python GatewayObjectService.py

You should see something like:

$ python GatewayObjectService.py
Gateway started
httpd started
coapd starte

Then with your browser or with curl access http://localhost:8000/ and you should see something like:
