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:
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

(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!
