Clarification of `observed data`

[brandomr]

Is the idea behind observed data that there would be some datasets that a user uploads which represent ground truth that could be used for assessing the model?

For example, if the model predicts crop production, then a observed data would be some set of data cubes which represent "actuals" for crop production (e.g. from the Central Statistical Agency etc)?

Correct, this field arose from our discussions on tracking provenance. A model could include some data that would be exposed as "cubes" in Causemos that the user could use for performing transforms or comparative analysis.

I added it as an array in the model structure because presumably these cubes would be available and known right away during model registration. We could also move this to be a flag on an actual cube if it makes it easier.
