Challenges with Data Model creation using CDF Toolkit Examples

For workItem you probably want to pint back to your work order - but your type is: workOrder: JSONObject

Look at linked Assets, exepct that your item should not pint to a list just one WorkOrder

yes it points to JSONObject instead of WorkOrder. This is the issue I am facing. I have created this data model using mentioned url’s example

If you look at the examples in toolkit as Activity pointing to Asset:

  assets:

    container:

      space: cdf_cdm

      externalId: CogniteActivity

      type: container

    containerPropertyIdentifier: assets

    name: Assets

    description: A list of assets the activity is related to.

    source:

      space: {{ schemaSpace }}

      externalId: {{ organization }}Asset

      version: v1

      type: view

==> we describe the source not type pointing to the Asset view and location for the view

you should try this in your code too….

​@Khilesh Sahu A few additional notes.

Very creative to look into the test data for Toolkit to find examples. However, note that this is risky as the test data is typically for a specific purpose, which is not to serve as an example. In this case you have selected a data model in the response format. Data models consists of views which comes both in request (write) and response (read) format. Instead, recommend you to use `cdf modules init/add` and select the models package to find examples. 

As Jan Inge is saying, when a connection shows up as a JSONObject in the UI it is typically because the connection is implemented as a direct relation and the `source` property is not specified. This is used to specify what the direct relation is pointing to. For more information see the API specification for the creation of views. (The YAML files in Toolkit is matching the API spec for views)

​@Khilesh Sahu One more question. What is it you are trying to achieve? Doing data modeling directly on configuration files is a very challenging task that is very error prone, I have been burned a lot when doing this. We are working at improving data modeling experience at Cognite. I am happy to take a call if you are interested. Let me know.

that would be great if we can discuss over call. Can you please setup a call

Thanks ​@Khilesh Sahu for opening the thread here. Please update the thread once we try out the suggestions.

Hello ​@Anders Albert ,
We have created a Data Model. And now this data model needs to be versioned controlled and distributed to multiple tenants. Model is kind of universal and hence it is same for all multiple tenants.

So what we are trying to do is converting this model to yamls, committing it to repos and then using cdf toolkit to deploy this to multiple tenant environments. We want to automate it via pipelines.

Thanks

​@Anders Albert and ​@Jan Inge Bergseth - I have tried similar approach as you suggested with our data model. Later, I tried with the mentioned example. 

From CDF Example in WorkItem.view.yaml
 

From our sample entiry.view.yaml

 

We got same issue in both case.
