Korbo is a proposal for a web semantic platform used to create a basket (korbo) of items collected in the LOD. The main aim of the platform is to analyze, augment and republish in LOD the items collected.

Elogio dell’impurezza (Sistema periodico - Zinco)
Sulle dispense stava scritto un dettaglio che alla prima lettura mi era
sfuggito, e cioè che il così tenero e delicato zinco, così arrendevole
davanti agli acidi, che ne fanno un solo boccone, si comporta invece in
modo assai diverso quando è molto puro: allora resiste ostinatamente
all’attacco.
Se ne potevano trarre due conseguenze filosofiche tra loro contrastanti:
l’elogio della purezza, che protegge dal male come un usbergo; l’elogio
dell’impurezza, che dà adito ai mutamenti, cioè alla vita.
[…]Perché la ruota giri, perché la vita viva, ci vogliono le
impurezze, e le impurezze delle impurezze.
