### Issues Identified in the Uploaded Datasets:

1. **Issue:** Incorrect graph-level attribute value in 'metadata.json' for ogbl-collab dataset.
   
   **Evidence:** The README.md file lists the number of nodes and edges, which doesn't match the metadata.json file.
   
   In README.md:
   ```
   * num_nodes: 310112
   * num_edges: 114922
   ```
   
   In metadata.json:
   ```
   "num_nodes": 20000,
   "num_edges": 114922,
   ```

   **Description:** The metadata.json file incorrectly lists the number of nodes for the ogbl-collab dataset. It should be 310112 as per the README.md.

2. **Issue:** Inconsistency in task descriptions between task_time_dependent_link_prediction_1.json and task_time_dependent_link_prediction_2.json files.

   **Evidence:** The task descriptions differ between the two JSON files.
   
   In task_time_dependent_link_prediction_1.json:
   ```
   "task": "link prediction",
   "task_type": "transductive link prediction"
   ```
   
   In task_time_dependent_link_prediction_2.json:
   ```
   "task": "link prediction",
   "task_type": "inductive link prediction"
   ```

   **Description:** The task descriptions for time-dependent link prediction are inconsistent, with one file specifying "transductive" and the other "inductive". This needs to be clarified.

3. **Issue:** Missing license information in the uploaded datasets.

   **Evidence:** The LICENSE file lacks any license information.
   
   **Description:** The absence of license details in the LICENSE file creates uncertainty about the datasets' usage terms. Including this information is crucial for clarity.

Feel free to ask if you need more information or further clarification on any of the identified issues.
