I have long been curious about the DBpedia ontology structure so I just took a
look at the ontology represented in
(https://dl.dropboxusercontent.com/u/375401/dbo_no_mappings.nt) as referenced
in the email below.
I normally start the evaluation of an ontology by looking at the top-down class
relationships. So, I did a search for the classes that were listed as a direct
subclass of owl#Thing to get a general idea of the organization of the DBpedia
class structure.
To say the least, I was sorely disappointed. Here are a few of the DBpedia
classes that are direct subclasses of owl#Thing: Food, Media, Work, Blazon,
Altitude, Language, Currency, Statistic, Diploma, Award, Agent, PublicService,
Disease, GrossDomesticProdutPerCapita, ElectionDiagram, Demographics,
Relationship, Medicine, List, BioMolecule. I gave up after this small sample.
It is obvious that the DBpedia community needs to worry a lot more about the
structure of the ontology itself rather than focusing on selecting a new
editor. A working group needs to be established to go back to the drawing board
and look at the DBpedia ontology form the top down. It certainly doesn't make
much sense as it is currently structured.

Subject: [DBpedia-discussion] Call for Ontology Editor demos for DBpedia
Dear all,
we are preparing a switch from the mappings wiki (http://mappings.dbpedia.org)
to another ontology editor and started to collect requirements/tools here:
https://docs.google.com/document/d/1HwtJJ3jIlrQAPwHYhvpw4a4Z4hZorTGaZTB8Bq8Y-TI/edit
We already have a demo for Webprotege thanks to Ismael Rodriguez, our GSoC
student. As we are lacking time and resources, we will probably only consider
editors with a running demo, so the community can try it.
Our main interest is of course to manage the DBpedia core ontology and push any
mappings to other ontologies in separate files. So we provide a core version
for demo purposes created with:
rapper -g dbpedia_2016-10.nt | grep -v
'\(http://schema.org\|http://www.wikidata.org\|http://www.ontologydesignpatterns.org\
<http://schema.org/|http:/www.wikidata.org/|http:/www.ontologydesignpatterns.org/>
)' > dbo_no_mappings.nt
https://dl.dropboxusercontent.com/u/375401/dbo_no_mappings.nt
(I hope that the regex didn't kick out anything essential or broke any
axioms...)
We would be very happy, if anyone from the semantic web community would make a
demo with their favorite editor and add a link to the Google Doc and post a
short message on the DBpedia discussion list[1] or on slack
https://dbpedia.slack.com/ .
This would help us to make a more informed decision. The next DBpedia Dev
online meeting will be on 2nd of August 14:00 (each first Wednesday per month).
Presentations of editors are also welcome. We will also discuss the editor
question during the DBpedia meeting in Amsterdam, co-located with SEMANTiCS on
14.9. http://wiki.dbpedia.org/meetings/Amsterdam2017
Thank you for your help!
