[tdwg-content] Bioblitz as rdf: does this make sense?

Hi Joel,

In the next day or so I will upload my TDWG talk to SlideShare, it explains
some of this.

**But remember this was just an experiment to see if it would work.***

The main advantage of creating URI's for commonly used things is that then
you can browse the connections between them and have them be the subjects of
triples.

See http://bit.ly/hTJkWz

It also allows you to connect additional information to a person or thing
that has a URI.

See attached png

In an ideal world, I might have done something like this.

http://notarealsite.org/genus_epithet

So a semantic web service would look up
http://notarealsite.org/Puma_concolor

Retrieve http://notarealsite.org/Puma_concolor.rdf

Which would give you:

1) list of what databases have that name

2) and what various kingdoms or Name Rules the different names fall under
(Plant, Animal etc)

   For example: "This is both a plant and an animal name"

3) What are the current valid names for each of the species listed. => The
list of related names you listed in your email.

=> *Puma concolor* (Linnaeus 1771)

I think this would be very useful since a number of data sources only list
the genus and specific epithet.

* For instance the index that is at the back of the Entomology Society of
America Annual Meeting Booklet

There are a couple of hurdles however.

1) What is the valid form of the name? Is there a machine that knows this or
will this need to be partially curated by humans?
    In some cases the "valid" name is not clear.

2) Even though there are ~20 million names, there are probably some valid
names that are not in the GNI.
    This is why I would encourage everyone to upload their names.

If these exist as URI's you get the following abilities

<gni_namestring:001> isSynonymOf <gni_namestring:002> etc.

Not that literals cannot be "subjects" of the subject-predicate-object
triple.

Also, as current configured names like *Callithrix melanura* (É. Geoffroy
1812) and *Callithrix melanura* (E. Geoffroy 1812) are seen as different.

* Also the É. will have to be properly escaped to be part of a valid URL.

So a simple text search might not find them.

So in summary if we are going to get past everyone marking up their own name
list in excel and then trying to merge them, we will need some architecture
than
can scale to millions of names and allow different groups to make assertions
about the relationships between those names.



Searching TaxonConcept.org:

For now you have two options for searching for names. (I am mainly
concentrating on the RDF representation right now)

You can use google "Puma concolor site:lod.taxonconcept.org" *Google seems
to prefer the .rdf version even though my sitemap specifies the .html.

Or use the Knowledge Base http://lsd.taxonconcept.org/fct/

I think I sent out a list of all the species collected at the BioBlitz, with
their matching species concept ID.

Did you not get this? I think it on the Google site.


*> iv. In what sense do you see Darwin Core as being deficient as a semantic
web representation?*

You agreed previously that some of the fields that currently use Literals
would be more efficiently and unambiguously represented as URI's.

I would characterize DarwinCore as "not optimal" rather than deficient.

There is no reason we can't still use the DarwinCore for what it is good
for, but it does not work very well for SPARQL queries and the LOD.

For instance, a search of occurrences of this *Callithrix melanura* (É.
Geoffroy 1812) will not return occurrences with *Callithrix melanura* (E.
Geoffroy 1812).

Respectfully,

- Pete
