I'm glad you're doing cool things with the data. A few comments/answers/questions ...<br>
<br>
i. The quests for consistently used canonical URIs, and consistently used canonical names are both, for now, somewhat quixotic, and I'm not sure one is more so than the other. GNA/GNI seems to be pursuing both. Is that a fair assessment?<br>
<br>
ii. I used opaque taxon concept URIs where they were readily available. Laziness motivated me to also use transparent identifiers for<br>
a. making sure each taxonConcept had an rdf:resource as an identifier, and<br>
b. asserting membership in the various rdfs:classes that I defined. But laziness has its drawbacks, and you point out a few of them. I think best practice when using either names or transparent URIs as identifiers would be to first run them through a spell checker and normalizer that would produce consistent usage of upper and lowe case characters, and probably drop authorship. Of course, this would produce some false positives when doing any sort of querying. But using UUIDs produces false negatives since they're not in common use. If we (as a community) follow through on the enthusiasm for creating competency cases that we showed in the Fall, it would be interesting to consider each case from the question of what's worse - false positives or false negatives. In any event, false positives can be weeded out by using the full scientific names and contextual information in the record, whereas false negatives may never be discovered.<br>
<br>
BTW, does anyone know a good spell checker for scientific names?<br>
<br>
iii. Mapping names to opaque URIs doesn't resolve the problems you raise below. Will the identifer for<br>
Carpodacus mexicanus<br>
be the same as the identifier for<br>
Carpodacus mexicanus (Statius Muller, 1776)?<br>
<br>
How about<br>
Arabis laevigata (Muhl. ex Willd.) Poir.<br>
vs.<br>
Arabis laevigata ?<br>
<br>
If yes, then why noy just use normalized names as identifiers? If no, then we'll get false negatives in the sorts of SPARQL queries that I gave at<div><br>
<a href="http://www.csee.umbc.edu/~jsachs/occurrences/queries/" target="_blank">http://www.csee.umbc.edu/~jsachs/occurrences/queries/</a><br>
<br></div>
BTW, is there a lookup service for <a href="http://taxonconcept.org" target="_blank">taxonconcept.org</a> identifiers (i.e. give a list of names, get a list of identifiers)?<br>
<br>
iv. In what sense do you see Darwin Core as being deficient as a semantic web representation?<br>
<br>

<br>
Implicit in each of the following notes is the question "Is this a good<br>
way to do it?":<br>
<br>
1. The data is "normalized" w.r.t. identification. "Normalized" is in<br>
quotes because I mean it in the sense that Steve Baskauf was using in his<br>
Fall 2010 series of posts. His meaning of the term makes sense to me, but<br>
many people (e.g. the OBO folks), take "normalized ontology" to mean<br>
"disentangled" (i.e. no multiple inheritance.)<br>
As an example, here's an occurrence with two crowdsourced determinations:<br>
<a href="http://www.cs.umbc.edu/~jsachs/occurrences/tdwg2010bioblitz_1644" target="_blank">http://www.cs.umbc.edu/~jsachs/occurrences/tdwg2010bioblitz_1644</a><br>
<br>
2. I used sequential integers for observation and identification IDs; in<br>
practice, a mechanism needs to be in place to prevent two people from<br>
assigning the same id to their respective identifications.<br>
<br>
3. My answer to Cam Webb's Question #1 from<br>
<a href="http://lists.tdwg.org/pipermail/tdwg-content/2010-October/001720.html" target="_blank">http://lists.tdwg.org/pipermail/tdwg-content/2010-October/001720.html</a><br>
is "both". In other words, just as "Joel Sachs" is both me and also my<br>
name, so<br>
<a href="http://www.cs.umbc.edu/~jsachs/occurrences/tdwg2010bioblitz_1668" target="_blank">http://www.cs.umbc.edu/~jsachs/occurrences/tdwg2010bioblitz_1668</a> is both<br>
an occurrence and an occurrence_id, expressed as:<br>
---<br>
<dwc:Occurrence<br>
rdf:about="<br>
<a href="http://www.cs.umbc.edu/~jsachs/occurrences/tdwg2010bioblitz_1644" target="_blank">http://www.cs.umbc.edu/~jsachs/occurrences/tdwg2010bioblitz_1644</a>"><br>
<dwc:occurrenceID><br>
<a href="http://www.cs.umbc.edu/~jsachs/occurrences/tdwg2010bioblitz_1644" target="_blank">http://www.cs.umbc.edu/~jsachs/occurrences/tdwg2010bioblitz_1644</a><br>
</dwc:occurrenceID><br>
<blah blah blah/><br>
</dwc:Occurrence><br>
---<br>
<br>
4. I was surprised to see that the Darwin Core Identification class has<br>
no<br>
"occurrenceID" or "specimenID" term. How is one supposed to tie an<br>
identification to an observation (assuming the identification is not<br>
in-lined, of course)? DeVries and Baskauf each mint their own terms for<br>
doing this (txn:identificationHasOccurrence, and<br>
sernec:basedOnOccurrence,<br>
respectively); I used dwc:occurrenceID as if it were a record level term.<br>
<br>
5. We had scope for multiple taxonConceptID columns in the Fusion table,<br>
and assigned lsids where possible. I also mean to work with Pete to<br>
assign<br>
GUIDs from <a href="http://taxoncocept.org" target="_blank">taxoncocept.org</a>. In addition, I assigned ethan taxon concept<br>
ids, which look like this:<br>
http:.//<a href="http://spire.umbc.edu/ethan/Coffea_arabica" target="_blank">spire.umbc.edu/ethan/Coffea_arabica</a><br>
<br>
In their argument over opaque vs. transparent taxonCoceptIDs, I was<br>
sympathetic to both Pete's and Gregor's arguments. Ultimately, if the<br>
tooling exists to always display the rdfs:labels every time I'm loooking<br>
at a list of opaqueIDs, then transparent IDs are unnecessary. But, for<br>
now, it's really helpful to look at an ID and know what it's referring<br>
to.<br>
<br>
(For species names not in the spire database, the rdf returned by<br>
http:.//<a href="http://spire.umbc.edu/ethan/$name" target="_blank">spire.umbc.edu/ethan/$name</a><br>
is simply an rdfs:seeAlso to<br>
http://<a href="http://gni.globalnames.org/name_strings?search_term=$name" target="_blank">http://gni.globalnames.org/name_strings?search_term=$name</a>)<br>
<br>
6. It was easy to assert membership in RDF classes corresponding to<br>
various Cape Cod categories of concern - invasive species, threatenened<br>
species, indicators, etc. You can see these classes at<br>
<a href="http://spire.umbc.edu/ontologies/lists" target="_blank">http://spire.umbc.edu/ontologies/lists</a> (Information of where these lists<br>
come from is included as rdfs:comments. I'll add further documentation,<br>
e.g. links to eml files.)<br>
<br>
Note that "ThingOfConcern" is defined as the superclass of all the other<br>
classes in the collection. The idea here is that people can create their<br>
own "ThingOfConcern" class, and then query for observations that are of<br>
concern to them. You can see sample sparql queries at<br>
<a href="http://www.csee.umbc.edu/~jsachs/occurrences/queries/sample.txt" target="_blank">http://www.csee.umbc.edu/~jsachs/occurrences/queries/sample.txt</a><br>
<br>
<br>
As an aside, I think we, as a community, should come up with a<br>
biodiversity benchmark suite of rdf data and corresponding sparql<br>
queries,<br>
that can be<br>
used to test the suitability and scalability of semantic web knowledge<br>
bases. I'll take this up in a future post (unless someone beats me to<br>
it).<br>
<br>
Comments, questions, and better ideas are welcome.<br>
<br>
Thanks -<br>
Joel.<br>
