We are currently researching this item and evaluating it for a future release.
If you have a moment, please let us know if you have a preference for how data item descriptions should be displayed in trends. For example, would you prefer to be able to configure the trend legend to show the item’s description, that the descriptions be shown under the plot area of the trend, or would you like them to be displayed in another way?
Let us know what your preference is by adding a comment below.

We are aware of the interest in this functionality but at this time it is not in our short-term plans to implement.

I find Dave Johnsen’ post excellent.
There are probably several ways to achieve “Extensible analytics”.
To give another customer’s view on this:
We use a Python Flask server hosting our Python code and a custom DR to call the functions. As Dave points out the CDR has some draw backs.
We can also call our Python Flask server using the REST possibility in Notifications but creating an event frame for each calculation is over kill.
One possible extension for Osisoft that would be more generic is to let the analysis service be able to send web requests with a setup much like the one in Notifications, but where the trigger is the same as a built-in analysis. Then it would be up to the hosting server to able to handle the web requests. The hosted functions could essentially do all that is needed i.e. retrieving data from PI and writing data back to PI. If a response to an attribute is required, then Osisoft should define the response format. (Mathworks or other calculation server providers would have to adapt the Osisoft format)
