What you propose works except that it is not stable to changes in nomenclature.

It is really no better than using the name.

You are still left with is Aedes triseriatus the same as Ochlerotatus triseriatus?

Data linked to http://example.org/Aedes_triseriatus is lost when the name is changed to http://example.org/Ochlerotatus_triseriatus

by citing a secundum

Yes if that publication is generally available and contains enough information that a set of general taxonomists will assign the same secundum to the same set of specimens.
and if everyone uses the exact same string of characters to when citing that secundum

the proposal saves this trivial processing time, but does not contribute to the problem

If this is so trivial then why does GBIF have one map for Felis concolor and one map for Puma concolor?

also why does the Barcode of life not have all their Aedes triseriatus and Ochlerotatus triseriatus mapped to one id rather than one for each name and misspelling?

se:Puma_concolor_sec._Smith

How many lexical variants of the string above are there likely to be?

The GNI name string URI's are simply a way to create a correctly formed URI from a name

I have the name string "Puma concolor (Linnaeus 1771)" in my database, the GNI has the same namestring.

We share a common algorithm to convert this into a standard uuid > '772d5162-f5aa-596c-98e0-a1c6c5a29bb9'

Now as long as the GNI has the same namestring I have, I can link our two databases together using the following URI.

http://gni.globalnames.org/name_strings/772d5162-f5aa-596c-98e0-a1c6c5a29bb9

These URI are simply to allow different databases to link to each other.

Names as they are structured do not make good URI's since certain characters need to be encoded so (Schmoe) becomes something like %28Schmoe%29 in a URL.

What you see as http://en.wikipedia.org/wiki/Cassia_(legume) is actually http://en.wikipedia.org/wiki/Cassia_%28legume%29

Also what about heterotypic synonyms? 

Things like & need to be replace with & Note that if you are not careful this can become &&&&& as it is re-encoded.

The GNI URI's are not for human consumption and if you view the entity above in a semantic web browser (see link below) it will substitute the URI for the human label.

Note that this is what Sig.ma has done with both the GNI URI's and the Geonames URI's.

The difference is that in this case the RDF has made it clear that we mean "the geospatial entity that is the state of Texas."

http://sig.ma/search?pid=013030d4a93abdd6206234b683c51b31

So these have a human label, unfortunately your current browser does not know to display it.

Also aren't TDWG URI's supposed to be opaque?

To an extent the TaxonConcept URI's are designed for humans in that it is easier to copy and paste and type V2ldt or http://lod.taxonconcept.org/ses/V2ldt.html

than 

Centrocercus minimus J. R. Young, C. E. Braun, S. J. Oyler-McCance, J. R. Hupp and T. W. Quinn 2000

and then recognize that this is the same thing as 

Centrocercus minimus J. R. Young, C. E. Braun, S. J. Oyler-McCance, J. R. Hupp and T. W. Quinn, 2000

Centrocercus minimus J. R. Young, C. E. Braun, S. J. Oyler-McCance, J. R. Hupp & T. W. Quinn, 2000

Centrocercus minimus J. R. Young, C. E. Braun, S. J. Oyler-McCance, J. R. Hupp & T. W. Quinn 2000

Centrocercus minimus J. R. Young, C. E. Braun, S. J. Oyler-McCance, J. R. Hupp et T. W. Quinn 2000

Centrocercus minimus J. R. Young, C. E. Braun, S. J. Oyler-McCance, J. R. Hupp et T. W. Quinn, 2000

Centrocercus minimus Young et al., 2000

It is also clear (or will be) that http://lod.taxonconcept.org/ses/V2ldt.html is about a species that is known by all those names and other synonyms through the GNI.

In contrast is not clear that Centrocercus minimus Young et al., 2000 is the same as all the other name variants listed above or that it may have other synonyms.

This is without getting into the variations in secundum.

So are people going to include all the possible name variants in their data sets or simply choose a uri that links to those variants for them?

The current species concepts are not complete in the sense that they do not make it clear as to what is and what is not an instance of a given species concept.

However, they are a start and since they contain links to both Wikipedia and Wikispecies, as well as a number of other annotative information sources, they will provide
humans a simple way to determine if what they have in their records is the same "kind of thing" as what is represented by the species concept URI.

Also there is nothing that says that taxonconcept.org could not be moved to some other institution in the future.

Respectfully,

- Pete

This always looks nice... However, with such proposals we, the
computer guys, make the concept-assessment someone elses problem (i.e.
the taxonomists, ecologists, pathologist, etc.), and, at the same
time, do not provide them the means to communicate. The assumption is
that a scientist or applied worker would know whether to add se:v6n7p
to a given taxon name or not.

With my taxonomer/pathologist hat on: I mostly have no clue which
concept XXX concolor is - and whether it is changed or not. Puma
concolor may be a different concept than Puma concolor. We are, of
course, guilty of communicating in a shamefully loose way (s.str., s.
lat. etc.), which could and should be improved by citing a secundum,
but beyond that: mapping concepts is a taxonomic opinion, no objective
truth.

So given that any trivial mapping mechanism can map multiple IDs (Puma
concolor, Eupuma concolor) to a single concept - the proposal saves
this trivial processing time, but does not contribute to the problem
of communicating in a way that is suitable to assess taxon concepts.

----

Aside: Please compare the highly linked, and generally correctly
linked Wikipedias with other content management system for the
advantage of human legible IDs [[Puma concolor]] over
http://x.y.net/node/234872561 - links. My own observation is that in
the latter case only a fraction of the desirable links are created,
and that these are quite often going to wrong, or perhaps obsoleted
places.

I therefore think:
se:Puma_concolor_sec._Smith
would be a much more useful mechanism than all the
computer-scientists-only proposals like se:v6n7p or
