Description

Constellation has long had an issue where a plugin could create attributes on a graph whose schema does not support them, and the behaviour has always been that that plugin should fail. I think instead we should allow plugins to create any attributes they want, and have views enforce schemas. For example, you might have a plugin create latitude and longitude attributes on a graph, but unless that graph is backed by the Analytic Schema (or one of its children) the Map View will not function as that is the minimum requirement of that view. We could build this functionality into the view framework - perhaps if a view is opened on top of an incompatible graph, it will default to a pane informing the user that their graph is incompatible with this view.

Steps to Reproduce

N/A

Expected behaviour:

Plugins can create attributes that are incompatible with underlying schemas.

Actual behaviour:

As per description, investiagte the statement: “We could build this functionality into the view framework - perhaps if a view is opened on top of an incompatible graph, it will default to a pane informing the user that their graph is incompatible with this view.” and implement if possible.

Reproduces how often:

Unable to quantify.

To follow up: different graph schemas will not work on all views. Simple Schema will not have default attributes content, geo or date time. When these schemas are in use, or if the current graph does not have the correct attributes registered that the view requires - The view should be disabled when opened. Upon adding those attributes the view should become active. Constellation should do nothing behind the users view - Constellation should alert the user that there is not a prerequisite met and therefore prompt them to add it if needed.
