My hypothesis is that taxonomists (and taxonomy) "want" linkage like this:
taxon name ==> correct authority information ==> correct
bibliographic metadata ==> actual original publication (full-text)
Although a linkage to a full text version of the publication would be
nice, it's not really what I wanted/needed when I posed the original
question. As a non-taxonomist, I've absorbed the point which has been
made repeatedly that in an Identification which simply provides a taxon
name is inadequate and that we should be specifying a taxon name usage
(i.e. name sensu publication, or name sec. publication). So I'm more
interested in a globally unique and reusable identifiers for names,
publications, and their intersections as TNUs. As such, I don't care
that much whether there is a linkage to a pdf of the publication as
long as I can refer to the TNU by a GUID and somebody else knows
exactly what taxon usage I'm talking about. I don't have a high degree
of confidence in using text strings like "Andropogon virginicus L. sec.
Radford et al. (1968)" as identifiers for TNUs because all it takes is
one missing period, no parentheses, or an extra space and then I have a
different string from somebody else. If the GUID is going to be a URI,
then I'd really like it to be dereferenceable to RDF. In the event
that the Linked Data world comes together, that gets me out of the
business of thrashing with all of the taxonomy stuff that I'm not
interested in doing myself. I believe that this is exactly one of the
points that Pete was trying to make. "a GUID for the curated, corrected bibliographic metadata as something distinct from a GUID for the actual publication."makes an artificial distinction between a publication and its metadata. I think the correct approach is to consider that the GUID represents the publication as a conceptual entity (i.e. non-information resource) which has properties that can be described by the bibilographic metadata, and which can have a representation as a pdf, jpg image, etc. With that approach, the GUID can be an unchanging identifier for the publication while the metadata and representations associated with it can be free to be corrected, updated, or improved.

Nor is the bibliographic metadata for a publication the same thing as the publication. My hypothesis is that taxonomists (and taxonomy) "want" linkage like this: taxon name ==> correct authority information ==> correct bibliographic metadata ==> actual original publication (full-text) In the general case, you can't determine the authority date by inspection of the actual original publication. You often need external information regarding publication mechanics. (Yes, I know that the date printed on the publication is the correct date of publication for most papers, but anyone who's dealt with taxonomic literature knows that there are many, many exceptions to that.) I'm not sure that they actually want: taxon name ==> actual original publication (full-text) Which is why I start thinking about a GUID for the curated, corrected bibliographic metadata as something distinct from a GUID for the actual publication. -Dean -- Dean Pentcheff pentcheff@gmail.com dpentche@nhm.org On Tue, Jan 4, 2011 at 1:01 PM, Peter DeVries <pete.devries@gmail.com> wrote:Hi Chris, You are missing one of the main benefits of Linked Data. Users do not want to curate their own bibliographic databases and related RDF, they want to simply link to a globally unique, resolvable identifier for that citation. For example: Felis concolor Linnaeus 1771 Linnaeus 1771 <= What specific publication is this? "Felis concolor" hasOriginalDescription <http://www.biodiversitylibrary.org/citation/234123412> If the BHL exposed semantic web URI's for each publication, then content experts could search the BHL, find it, and then link to it with a simple resolvable URI. The alternative is that Steve, et al., will create their own identifiers for specific publications, code their own local bibliographic databases. In essence, each group or individual then continues to duplicate the efforts of others. Right now, I have duplicated your functionality in my species concepts. Ideally, I would have done this: <SpeciesConcept> hasOriginalDescription <http://www.biodiversitylibrary.org/citation/234123412> <SpeciesConcept> hasRevisionalDescription <http://www.biodiversitylibrary.org/citation/234124356> Not only are my concepts then linked to your citations, any other data sets that link to your citations are findable. For instance, who else has data sets that link to this citation?

Documentation is here: http://www.biodiversitylibrary.org/openurlhelp.aspx And linked from our broader documentation here: http://biodivlib.wikispaces.com/Developer+Tools+and+API Here's an example, referenced in the documentation, for querying on a monograph/book: http://www.biodiversitylibrary.org/openurl?genre=book&title=Manual+of+North+American+Diptera&aufirst=Samuel+Wendell&aulast=Williston&publisher=New+Haven+:J.T.+Hathaway,&date=1908&spage=16&format=xml You can also query based on common abbreviations, like Sp. Pl.: http://www.biodiversitylibrary.org/openurl?stitle=Sp.%20Pl.&date=1753&format=xml MOBOT's Tropicos uses the OpenURL resolver to link to protologues, as in this example: http://www.tropicos.org/Name/2735114 With Tropicos we have an authority record for each journal or monographic title. We match Tropicos' TitleID to BHL's TitleID & use that as a more direct link to the appropriate reference, but still send collation & other info to get to the appropriate page, as in this link: http://www.biodiversitylibrary.org/openurl?pid=title:626&volume=5&issue=&spage=244&date=1830 I know that this is insufficient for zoology & other natural sciences beyond botany, where we need to be able to support citations like "Pallas 1767", which may or may not be preparsed into appropriate fields. A known problem, for sure, and one that we're eager to address, pending funding from NSF.

Most recently in this blog post. http://www.taxonconcept.org/taxonconcept-blog/2010/8/5/why-linked-open-data-makes-sense-for-biodiversity-informatic.html What I have realized is that, for many works that are out of copyright, Google books has already scanned and converted them to PDF. You can use these, even extract the relevant PDF pages as long as you keep the Google watermark. This is what I have done for the Cougar. http://lod.taxonconcept.org/ses/v6n7p.html For more recent works you may be able to link to the article PDF. As in this spider example. http://lod.taxonconcept.org/ses/2mqjL.html We also need a URI for to uniquely identify authors and in the absence of a better solution, I have been using, and in some cases creating, entries in Wikipedia which currently has over 5,000 taxonomic author profiles. This results in usable RDF via DBpedia. As you can see in the RDF in this example. http://lod.taxonconcept.org/ses/v6n7p.rdf And in the Knowledge Base <http://lsd.taxonconcept.org/describe/?url=http%3A%2F%2Flod.taxonconcept.org%2Fses%2Fv6n7p%23OriginalDescriptionThat said, I have also been experimenting with this. http://lod.taxonconcept.org/people/sci_people_1700.rdf About: Carl Linnaeus http://bit.ly/gLgElf - Pete On Mon, Jan 3, 2011 at 7:47 PM, Steve Baskauf <steve.baskauf@vanderbilt.edu> wrote:I was reviewing some of the previous posts on taxon name usages in an attempt to understand them better. I have learned that the Global Names Index is an attempt to catalog taxon names and that it is possible to generate a URI that points to a name there. Is there a parallel effort to do the same thing for literature references? In other words, if I want to describe the TNU: Andropogon virginicus L. sec. Radford et al. (1968) I think I could find a URI GUID for the name Andropogon virginicus . But is there some place where I could find a unique identifier, or better a URL, or best a URI providing RDF/XML for Linnaeus 1753 (the author and publication for the name) and for Radford et al.1968 (the author and publication that expresses the usage I'm intending). I suppose that this question has previously been answered in the in the many posts on taxon names, concepts, etc. However, since usually my brain goes numb and my eyes glaze over in those threads, I probably missed it.
