Metadata is hugely important in the lifecycle and maintenance of good data. Workspaces allows you to add, update, maintain and export metadata for datasets.

As soon as a dataset has begun uploading, you can add metadata using the Add Metadata function.

From the Dataset Overview or Dataset Preview, select the 'Edit metadata' option in the sidebar.

 

Adding metadata manually

The following fields are available to specify or change metadata for the dataset:

  • Title – The title of the dataset.
  • Source – The source of the dataset. This is a text field which could be used to supply an URL or any other description of the source of the data.
  • Description – A description of the dataset.

The following metadata can also be set for each column in the dataset:

  • Label – a label for the dataset column.
  • Description – a description of the column.

Adding metadata from a file

Instead of adding all of the metadata for your table manually, you can import the metadata from a file in your workspace.

Firstly, you should upload your TDF file using the normal upload process.

Once your file is uploaded into your workspace, navigate to the Edit Metadata page of the table you're interested in and select the 'Import from File' button.

Note, you need to confirm that you want to overwrite any existing metadata if it already exists.

Either search or navigate to your TDF XML file and select 'Confirm'.

Your metadata will be added to the form where you can edit or check it.

Note that the metadata for the table columns is matched based on the header of the column rather than the order that the metadata file is in.

 

Copying metadata from another table

From the Edit Metadata page, you can also import metadata from other tables in your workspace.

Select the 'Copy from another Dataset'. Again, if there is already metadata set then you'll need to confirm that you want to overwrite this.

Select the table which you want to copy metadata from and click 'Confirm' and your metadata will show in the form.

 

Viewing metadata

Dataset metadata can be viewed in the Dataset Preview as well as in the Edit Metadata tab.

 

Exporting metadata

You can easily create an XML copy of your metadata by using the 'Export to Metadata' button.

Select the destination for your file and click 'Confirm'. Your metadata file will be stored in your workspace files folder.

 

Metadata format

Workspaces currently support the use of TDF (Table Definition Format) files for importing and exporting metadata.

TDF files are XML formatted files which describe the format of a data table.
