[tdwg-tag] provenance chains and DwC:recordedBy

In preparation for the tdwg bioblitz, I'd like to configure our Spotter
tool (http://spire.umbc.edu/spotter) to compose DwC records. Currently, it
uses an observation ontology that we whipped up a few years ago.
(Here's an illustrative record -
For the most part, the mapping is straightforward. However, I'm wondering about
two terms: "hasObserver" and "hasReporter". 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.
Since one of the goals of the bioblitz is figuring out good ways to use
DwC in citizen science, I'm interested in opinions on whether we should preserve the
and include these non-DwC terms in the bioblitz data profile.
Many thanks -
