The HXL Postcard provides a quick summary of the most common HXL hashtags and attributes. You can find more in the full HXL standard, and can also create your own.

The HXL Hashtag Chooser helps you choose hashtags and attributes interactively by answering questions about your data.

The HXL Tag Assist tool will show you different HXL hashtags in datasets that organisations have already uploaded to HDX.

The detailed list of HXL hashtags and attributes is available in the HXL hashtag dictionary. Finally, an up-to-date machine-readable version of the hashtag dictionary is available on HDX.
