Yury Katkov: As far as I know, sometimes thedrafts of ISO standards are available for free. Is there a free draft version somewhere

One can get some text information within the ISO database, here is the documentation: http://isotc.iso.org/livelink/livelink?func=ll&objId=8421449&objActi...

but you don't get RDF specifications etc.

that is a search at: http://www.iso.org/obp/ui/#search

for for example: cutting and grinding

(there is sofar no direct link to a search request)

reveals a lot of unclickable items, but just ISO numbers and a little text. but then the database browsing is still in beta.
