HXL and HDX Tools

| January 9, 2021

You can use Data Check to compare your HXL-tagged dataset against a collection of validation rules that you can configure. Data Check identifies the errors in your data such as spelling mistakes, incorrect geographical codes, extra whitespace, numerical outliers, and incorrect data types.

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.

At this stage, Quick Charts are working with a limited number of HXL hashtags, but we are constantly expanding the list. The current set of JSON-encoded Quick Charts recipes is available on GitHub.

Every Quick Chart on HDX includes a small link icon at the bottom, that will give you HTML markup to copy into a web page or blog to add the chart. The chart will be live, and will update whenever the source data updates.

If your data uses HXL hashtags, then the Quick Charts tool can automatically create customizable graphs and key figures to help you highlight the most important aspects of your dataset. Quick Charts require the following:

  1. The first resource in your dataset (stored on HDX or remotely) must have HXL hashtags.
  2. That dataset must have the HDX category tag 'HXL' (not to be confused with the actual HXL hashtags).

The Humanitarian Exchange Language (HXL) is a simple standard for messy data. It is based on spreadsheet formats such as CSV or Excel. The standard works by adding hashtags with semantic information in the row between the column header and data allow software to validate, clean, merge and analyse data more easily.

HDX is currently adding features to visualise HXL-tagged data. To learn more about HXL and who's currently using it, visit the HXL standard site.
