Edit Classifications

Caliper uses VocBench as its editing platform. VocBench is an open source project maintained by the University of Tor Vergata (Rome, Italy), to manage resources such as thesauri, classifications, glossaries, taxonomies, ontologies. It natively supports RDF and related vocabularies, such as SKOS, SKOS-XL and OWL. VocBench is widely adopted by large institutional users

Main features of VocBench:

  • Web-based
  • Login and work using a specific editorial role, e.g. "editor" or "validator"
  • Create new vocabularies/classification, in different ways:
    • manually, from GUI
    • by importing data from spreadsheets
    • loading RDF vocabularies generated outside VocBench 
  • Create new correspondences
  • Edit any part of an already loaded classification
  • Edit any part of the associated metadata
  • Export data in various formats, incl. RDF
  • Query its internal SPARQL query endpoint and save results as Json, CSV, TSV, XLSX, OSD
  • Edit, import and export ontologies to be used together with the data
  • Triplestore-independent

If you are curious about how VocBench looks like, you can:

  • enter VocBench at Caliper by using a read-only guest account (credentials:, guest).
    • Once logged in, select a project, then click on "Data" (top left), to see the classifications. 
  • check out PMKI, the read-only version of VocBench that does not require creating an account.

The interfaces of VocBench and PMKI are very similar, as it is shown in the two figure below.

Being dedicated to public visualization, PMKI adopts a more common terminology for its interface than the one used in VocBench.
