We use three tools to visualize and search statistical classifications and their correspondences.
SKOSMOS offers an intuitive interface to browse classifications hierarchically. Correspondences are shown together with the item to which they refer.
Main features of SKOSMOS:
- You can search for items names in any language available, or for codes
- You can search for items either inside a given classification, or against all of them
- Tip: By default, search in Skosmos looks for items starting with the value you typed. So, if you type "wheat" it will return "Wheat, seed" but not "Buckwheat". For a more general search, use "*" before and after your input value, like in "*wheat*".
Correspondences are visible once you access a specific classification entry, as shown the picture above.
PMKI offers a rapid mechanism to visualize content being edited in VocBench, but it does not require an account on VocBench.
Correspondences are visualized in two ways: together with item to which they refer, and separately, in a dedicated tab.
- PMKI is the recommended tool to visualize some resources, such as FoodEx2 2016 and the Geopolitical Ontology.
- Geographical classifications (such as M49 or SDG Country Grouping) will be available in PMKI soon.
PMKI is good to look at how classifications look like in the editing environment.
Drupal is the content management system used for the Caliper website. As Drupal can consume RDF natively, we also use it to visualize classifications and to offer a convenient searching tool against classifications and correspondences. We use Drupal also to automatically compile reports about all content of Caliper.

While the pictures below show how classifications are visualized. To the left, the hierarchy structure, to the right a specific item.
