If no HXL hashtag is a perfect match, you still have a few options: 
  • You can use a more general hashtag combined with attributes, e.g. #affected +refugees +injured +elderly +f for the number of elderly refugee women injured. 
  • You can use the general #indicator hashtag combined with your own custom attribute to identify an indicator specific to your own organisation, project, or cluster, e.g. #indicator +facilities_damaged +num for the number of facilities damaged (where +facilities_damaged is the attribute that you created). 
  • If no general hashtag applies, you can create your own custom hashtag beginning with “x_”, e.g. #x_virulence for the virulence of a disease.
 More information is available in the HXL standard, 3.2. Creating extension hashtags.
