EPIC: Create vocabulary for DwC basisOfRecord

[ramonawalls]

BCO will house a new exemplar controlled vocabulary for the Darwin Core property basisOfRecord (BoR, http://rs.tdwg.org/dwc/terms/basisOfRecord).

The current vocabulary for BoR is already imported into BCO, and classified as appropriate.

BoR as a Darwin Core property is defined as "The specific nature of the data record." In BCO, it will need to be defined. It is generally understood that the BoR is the evidence of an occurence, which is in turn the existence of an organism (organismal entity, in BCO) at a particular place and time.

Since github has non-hierarchical issues, this issue is intended to serve as an epic, that is, as a gathering place for other issues which will describe the specific tasks to be completed in order to complete the goal of this issue.

Please put your comments on specific issues, rather than here, whenever possible. As we create issues, they should mention this epic so that they will be gathered here.
