Need to add geological eras to adj.pert

[fcbr]

An era could also be seen as an adjective (as in "Bathonian formations", for example). Should we also create the same synsets for the ISC eras as adjectives, not just nouns?

[fcbr]

Please notice that this is already the case for existing eras in PWN:

$ cd wordnet-dsl/dict/
$ grep Jurassic adj*.txt
adj.pert.txt:w: Jurassic pe noun.time:Jurassic
adj.pert.txt:w: pre-Jurassic pe noun.time:Jurassic
adj.pert.txt:g: of or relating to or denoting the time before the Jurassic period

So in order to be consistent, we need to add the new eras in noun.geotime to adj.pert too.

commit own-pt/own-en@e92f987 added pertainyms for the most frequent (at least 10 citations) eras and periods in the Onepetro corpus.

I would close it since it is an ongoing work . I also had some discussion about it in GWC and we can also following another path: create mix pos tag like nadj for zero derivared adjectives
