* add exemplar for telecom, hardware and field comparison.adoc

No exemplar yet for field comp'
exemplar for telecom and hardware refers to Vocab guildeline. But as the controlled vocab are pending (not served by a vocabulary server yet, I do not know how i should fill the `*_vocabulary` attribute.

* Update OG_Format.adoc

resolve conversation 'V' toward 'v'
