The HXL Tag Assist tool will show you different HXL hashtags in datasets that organisations have already uploaded to HDX. You can find a quick (and portable) list of the core HXL hashtags on the HXL Postcard. 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.
