TASK 1. Browse and lookup ONS concepts

ONS has been listen in the public ontology repository Bioportal.

Upon opening, the Bioportal summary page for ONS is shown.

This page reports some general information about ONS (i.e. the number of classes, the number of visits, and so on). The page also lists the version history (Bioportal retrieves changes from the ONS Github repository daily) and, more importantly, creates download links for the latest version of the ontology in various formats. The user would be typically interested in either:

• CSV format, to easily and quickly browse classes and definition in a spreadsheet software. The resulting CSV file contains various columns mapping each class (column “Class ID”) to various properties. In the “Class ID” reports the URL of the class, not particularly informative to humans. Typically the user would be interested in the columns:
  • “Preferred label” which reports a human-readable label for the class
  • “Definitions” reporting the textual definition of the class

Which are the most useful when searching ONS for a particular class. Other columns of the CSV file, reports the various properties of a class.

• OWL format, to browse or make local changes using an ontology software, such as Protègè (see TASK 2. of this wiki)

ONS classes can be browsed by clicking on the "Classes" tab. Here, the left panel report the hierarchical organisation of ONS. The hierarchy of concepts can be expanded or reduced to show more general or more granular terms of the ontology. By clicking on a class in the hierarchy, the right panel shows information about the selected class (i.e. its definition, label, properties, etc). The "Jump to" search tool allows to search for specific classes. An autocompletion functionality is available, so if the exact name of a class in ONS is not known, it can be found by typing few letters.
