Project Description

We are currently developing the ability to add additional protocols in to ROXIE. In doing this, it will be possible to also add support for protocols currently being used in Internet of Things (IoT) projects.

There are several protocols being used in IoT projects, or you can suggest any protocol you think might be of value:

  • Constrained Application Protocol (CoAP) - Defined by the Internet Engineering Task Force (IETF) Constrained RESTful environments (CoRE) Working Group as a RESTful protocol for the sorts of constrained devices used in IoT projects.
  • MQTTextremely lightweight publish/subscribe messaging transport..
  • External REST protocol emulation - Roxie currently supports REST queries, but current Roxie protocols expect query input and output to conform to a standard "envelope" in which inputs and results are embedded.  If we want to be able to inter-operate with existing projects we need to be able to completely emulate their messaging formats.  Protocol emulation would allow roxie to match existing RESTful structures in use by outside projects.  ECL would have full control over the entire request and response object structure.
  • Propose another protocol of your choosing - IoT or otherwise.  Make a case for how it would improve the HPCC or what systems the HPCC will be able to inter-operate with.
  • IoT project INTEROP - If there is already a specific IoT project you are interested in, perhaps you could focus on what it takes to inter-operate with that project.

By the mid term review we would expect you to have:

  • Produced a set of test cases to test protocol or project interoperability.
  • Implemented a roxie protocol plugin that allows devices to interact with roxie queries using the selected protocol.
