If I understand correctly from http://rs.tdwg.org/dwc/terms/#recordedBy you would concatenate the observer and then the reporter in one single string that will be transferred in recordedBy. What should go first, if them observer or the reporter i dont know, in the case of Bioblitz I would say the observer (it is all about giving credit to people on the field no?). Of course this is a data loose transformation as the concatenated list will not tell you what is what.
I feel I am missing something...

Currently, it uses an observation ontology that we whipped up a few years ago. (Here's an illustrative record - http://spire.umbc.edu/spotter/observation/data.php?record=1534)

We distinguished between these two terms to accommodate situations where a student makes an observation, but her teacher reports it. Similarly, in a bioblitz event, one model is that a survey team leader will fill out and submit a spreadsheet comprised of the observations made by members of the survey team.
> Both these terms seem to map to DwC:recordedBy. According to http://rs.tdwg.org/dwc/terms/#recordedBy, "The primary collector or observer, especially one who applies a personal identifier (recordNumber), should be listed first." So if we simply listed observer followed by reporter, we would comply with the spec. Of course, the ordering would be lost in typical rdf representations, since triples are considered unordered. And whether in rdf or in text, the distinction between observer and reporter would be pretty much lost.
