Metadata Explained

Example: Dataset metadata missing or incomplete

How to notice if this is a problem

*   The dataset will not download when using the disk icon
*   Tools error when using a specific dataset that has been used before successfully
*   Tools error with a message that ends with: `OSError: [Errno 2] No such file or directory`. Note that not all failures of this type are due to metadata and may simply be a cluster failure - rerunning the job may resolve the problem instead, but try the solution first.

Solution

*   Reset the metadata on the dataset(s). This may be an uploaded dataset or one created by prior tools. It could be one of the input datasets to a failed job.
    *   Directly reset metadata: click on the the dataset's ![pencil](/images/icons/pencil.png "pencil") icon, then click into the _Dataype_ tab and reset to the correct format. Don't forget to save! The dataset will turn yellow in the history while the job is processing.
    *   Autodetect: click on the dataset's ![pencil](/images/icons/pencil.png "pencil") icon, cthen lick on the _**Auto-detect**_ button found near the bottom of the _**Edit Attributes**_ form. The dataset will turn yellow in the history while the job is processing.

If this does not resolve the problem

*   If resetting metadata does fix the issue, then there may have been a transient cluster job failure. Re-run the job at least once.
