| description | string | User-provided DAG description, which can consist of several sentences or paragraphs that describe DAG contents. |
| file_token | string | The key containing the encrypted path to the file. Encryption and decryption take place only on the server. This prevents the client from reading an non-DAG file. This also ensures API extensibility, |

| has_task_concurrency_limits | boolean | Whether the DAG has task concurrency limits *New in version 2.3.0* |
| is_active | boolean | Whether the DAG is currently seen by the scheduler(s). *New in version 2.1.1* *Changed in version 2.2.0*: Field is read-only. |
| is_paused | boolean | Whether the DAG is paused. |
| is_subdag | boolean | Whether the DAG is SubDAG. |
| last_expired | string | Time when the DAG last received a refresh signal (e.g. the DAG's "refresh" button was clicked in the web UI) *New in version 2.3.0* |
| last_parsed_time | string | The last time the DAG was parsed. *New in version 2.3.0* |
| last_pickled | string | The last time the DAG was pickled. *New in version 2.3.0* |
| max_active_runs | integer | Maximum number of active DAG runs for the DAG *New in version 2.3.0* |
| max_active_tasks | integer | Maximum number of active tasks that can be run on the DAG *New in version 2.3.0* |
| next_dagrun | string | The logical date of the next dag run. *New in version 2.3.0* |
| next_dagrun_create_after | string | Earliest time at which this ``next_dagrun`` can be created. *New in version 2.3.0* |
| next_dagrun_data_interval_end | string | The end of the interval of the next dag run. *New in version 2.3.0* |
| next_dagrun_data_interval_start | string | The start of the interval of the next dag run. *New in version 2.3.0* |
| owners | array | |
| pickle_id | string | Foreign key to the latest pickle_id *New in version 2.3.0* |
