Jan 14 - New browsing interface available - PMKI

A new browsing interface is now available in Caliper. All classifications available in Caliper are now also loaded in a test instance of PMKI, a tool developed by the University of Tor Vergata and based on VocBench, the editing tool using in Caliper. This is the third browsing interface currently available in Caliper. Visit the page Browse for a pointer to all of them (credentials: "caliper").

What is PMKI good for? PMKI presents the user with different tabs (Concept, Collection, Scheme, Property, Alignments), which can be used to have a closer look at those types of information. For example, the tab "Scheme" allows one to select only one or more concept schemes, when several are available. Cf. datasets CPC2.1 and FoodEx2.
