Re: [science-iwg] Merge Python & Eclipse with EASE

[Scott Lewis <slewis@xxxxxxxxxxxxx>]

Hi Folks,

This is indeed very interesting.

Another technology to add to the mix:   Using Py4j, I've written what I'm calling an 'osgiservicebridge' [1].  What it does is dynamically expose Python object instances to the OSGi service registry, and allow Java-based OSGi services to be accessed from Python.  

You can think of it as making OSGi services available to Python (Python consumer -> Java provider), and Python objects as impls of OSGi services (Java consumer -> Python provider).  The main benefits are that all of the OSGi service dynamics, versioning, discovery, separation between contract and impl, interoperability with DS, etc are maintained, since everything is done via the OSGi Remote Service Admin specification and ECF's impl of that spec.   There are no dependencies directly on Eclipse or specific UI technologies although obviously since Eclipse is based upon OSGi everything is completely transferable to Eclipse-based apps.

Consumers are using this to allow OSGi-based Edge analytics systems to use Python for implementing parts of the analytics:  e.g. training/learning...and OSGi for other parts.

Hi all,

Yesterday evening at the Toulouse JUG, Alain Bernard gave a great talk and demo on the Python & EASE integration and how it is being used with the Airbus PerfIDE workbench. 

So I wanted to share the video here (it is in French, but the slides & demo are in English and speak for themselves). https://youtu.be/gShXE0OMTXI?t=1h34m41s

Particularly nice to see the custom module that has been developed for Airbus and how that integrates with the visualisation tool, so that a Python script can be used to control the plotting - see this part of the demo https://youtu.be/gShXE0OMTXI?t=1h48m55s

Looking forward to seeing more of it in June at our SWG event & EclipseCon France. 

Tracy
