Prefer Dublin Core and Darwin Core over schema.org

[aaronc]

I see that we are using schema.org for some of our schemas particularly for simple things like name, description, etc. Dublin Core is more widely adopted among the scientific community and covers all of these things. In particular, Darwin Core (which is based on Dublin Core) is the de facto standard in the biodiversity space. Most of the large GBIF datasets use Darwin Core. Wherever possible we should align with ontologies used broadly in the scientific community. Schema.org is a bit more tech industry aligned - not necessarily a bad choice, but Dublin Core and Darwin Core will make scientific dataset interoperability (for instance with GBIF) easier.

I'm aligned with this thinking. I left some thoughts as it pertains to project update posts here: #82 (comment)
