add EARMARK

[chiarcos]

Yet another early (pre-2010) ontology for linguistic annotation to be compared with the other approaches. I thought that had been largely abandoned, but it continues to be used by FRED (http://wit.istc.cnr.it/stlab-tools/fred/demo/; along with NIF, that is) and [apparently] occasionally in the DH context, too.

However, the original earmark site (http://earmark.sourceforge.net) only contains a redirect to https://essepuntato.it/lode/ which is a machine reading service, not the EARMARK documentation. It does use the actual EARMARK documentation links as illustrative data (https://essepuntato.it/2008/12/earmark), but these don't work anymore.

Suggestion: Add EARMARK to related vocabularies and explore its characteristics, if any reliable and up-to-date documentation can be identified. Given its current state of documentation (and use) it should not be the basis for a harmonization effort, but it can inform such an enterprise.
