transform_value_for_tile for resource-instance datatype simplification/enhancement

[whatisgalen]

The ResourceInstanceDataType class supports this kind of value for importing from, for example, csv:

def transform_value_for_tile(self, value, **kwargs):
        try:
            return json.loads(value)
        except ValueError:
            # do this if json (invalid) is formatted with single quotes, re #6390
            try:
                return ast.literal_eval(value)
            except:
                return value
        except TypeError:
            # data should come in as json but python list is accepted as well
            if isinstance(value, list):
                return value

Meaning that each value has to look like this:

{
    "resourceName": "",
    "ontologyProperty": "",
    "inverseOntologyProperty": "",
    "resourceId": ""
}

This datatype already considers data valid if it only contains a value for "resoruceId" and nothing else. It would be nice if a user could import a value that only contained a resourceId uuid string and then the datatype method populates the rest of the boilerplate with empty string values.

Funny, I just hacked out a version of this in #11596 (not that it's factored perfectly), and I'd definitely be up to pull it out into its own PR or collab on your implementation. Say the word.

I'm hacking out a proof of concept right now to import either a single uuid string or a list of uuid strings from a csv cell. I'd be happy to push to a branch to see if there's a collab that makes sense

My hack also took a list of python UUID types (not strings), but doesn't handle a jumbled array of some-of-one-and-some-of-the-other, which would be easy to handle if factored well. Happy to review!
