Using a property from a well-known vocabulary like SKOS would be good.&nbsp;
But there is the problem that Bob mentioned.&nbsp; Also, I'm not clear about
the entailments that would result from skos:note and skos:example being
declared as annotation properties. [1]<br>
<br>
I think that the intention of the RDF guide was that as new properties
were added to DwC, they would be birthed simultaneously in both the
IRI-object and literal-object versions without necessitating a change
to the guide itself.&nbsp; Whether that is allowed technically, I don't
know.&nbsp; When we add terms to the normative DwC document, they show up in
the non-normative documents of the standard (e.g. the quick reference
guide) without additional action.&nbsp; If that's not a problem, then adding
them to the list in the RDF guide also should be able to happen
routinely.&nbsp; <br>
<br>
This is a good topic for the vocabulary maintenance task group
(currently in the process of formation).<br>

of the RDF Guide? That is, would it be explicitly declared as taking a
literal object and be accompanied by an IRI version
dwcattributes:exampleIRI? Would this require adding to the scope of
the Guide? (Is the scope of the Guide sufficient for the current
enterprise in general?)

The proposals to use skos:example are appealing on several grounds.
But  skos:note and its subproperties (including skos:example) can take
literals or references [1].  To me, that weighs   more than the
baggage of minting two new terms.

Dear all,

We have been musing about how to make it easy to mark up examples in
human-readable renditions, and how best to enable that in the RDF as source.
I think, Ramona, that the separate example usage annotations solve multiple
real problems that we have right now and align us well with how we would
like to manage Darwin Core in BCO. Thus, though it may not be necessary for
Darwin Core at this time, I think it will actually help us.

Thus, I would like to formally amend the original proposal. Specifically, I
would add a new attribute dwcattributes:example. I would add an instance of
this attribute for every example in every Darwin Core term. All examples
would be removed from the definitions and comments. The recommendations on
controlled vocabularies would still be moved consistently to the comments as
in the original proposal.

Given this proposed amendment, I'll change the end-date for commentary on
this proposal to 5 Mar 2015.

Cheers,

John

Dear all,

During the process of reviewing the recent set of changes to the Darwin
Core standard in early November 2014, it was proposed to make the
definitions and comments for terms more consistent in their treatment of
content recommendations. The specific proposal is logged in the Darwin
Core
issue tracker as <a class="moz-txt-link-freetext" href="https://github.com/tdwg/dwc/issues/26">https://github.com/tdwg/dwc/issues/26</a>.

The gist of the proposal is that recommendations on how to populate a
term
are often in the definition whereas we would like them to be consistently
in the comments section. The list of affected terms is given below for
reference.

This message is to elicit responses from any who might have a reason to
recommend against these changes, which are not semantic in nature. We
will
leave this proposal open for commentary until 19 February 2015 unless
further discussion arises resulting in amendments.

Cheers,

John
