Speleology terms for tagging from italian

Hello,

I wrote an import wiki to document an import of cave entrances, but I have some difficulties in tagging. I also posted a message about it on tagging mailing list.

I need help for the following key=value.

General question: for cave entrance morphology (not cave morphology), with key should be used? cave_entrance:type=* ?

About cave_entrance:type values, dataset is in italian language and I don't have skills to translate speleo terms correctly; Below a list with frequency and my guesses:

• Pozzo 5814 well, pit
• Pozzetto 1641 pit, cockpipt
• Cunicolo 317 cuniculus
• Caverna 263 cavern
• Galleria 236 gallery, tunnel
• Cavernetta 138 small_cavern
• Fessura 124 crack, gap
• Scivolo 92 slide
• Baratro 34 abyss, chasm
• Riparo sottoroccia 23 rock_shelter (a shelter with rocky ceiling)
• Meandro 16 meander
• Voragine 14 chasm, sinkhole

Any suggestions?
Better set a description:it/note tag instead and leave the job for speleologists who (hopefully) will come across?
