 * `id`: Every record in every node in a data commons has the unique property `id`, which is not submitted by the data contributor but rather generated on the backend. The value of the property `id` is a 128-bit UUID (a unique 32 character identifier).
 
-* `project_id` and `code`: Every project record in a data commons is linked to a parent `program` node and has the properties `project_id` and a `code`. The property `project_id` is the dash-separated combination of `program` and `code`. For example, if your project was named 'Experiment1', and this project was part of the 'Pilot' program, the project's `project_id` would be 'Pilot-Experiment1', and the project's `code` would be 'Experiment1'. Finally, just like every record in the data commons, the project has the unique property `id`, which is not to be confused with the project's `project_id`.
