rename umbel_reference_concepts.n3 to rdf

https://github.com/structureddynamics/UMBEL/blob/master/Reference%20Structure/umbel_reference_concepts.n3 is not n3 but rdf: rename accordingly

how are supertypes assigned?

I'm trying to find all RCs related to Food & Drink and I thought they all would have the supertype umbel:FoodDrink. I started with Cuisines:

• there are a total of 55 cuisines, see 1
• of them 31 are rdfs:subClassOf umbel:FoodDrink, see 2
• all 55 are rdf:type rc:Cuisine but not subClassOf thereof, see 3
• rc:Cuisine is rdfs:subClassOf umbel:FoodDrink but this so all individual cuisines will get rdf:type umbel:FoodDrink

Why all 54 cuisines have rdf:type umbel:FoodDrink but only 30 of them have rdfs:subClassOf umbel:FoodDrink? Should I use rdf:type or rdfs:subClassOf for my task?

rdfcat -x umbel_reference_concepts.n3 -out ntriple > umbel_reference_concepts.nt
perl -S prefixize.pl umbel_reference_concepts.nt > umbel_reference_concepts1.ttl
1: grep -i "cuisine.* rdf:type umbel:RefConcept" umbel_reference_concepts1.ttl
2: grep -i "cuisine.*FoodDrink" umbel_reference_concepts1.ttl
3: grep -i "cuisine.*rc:Cuisine" umbel_reference_concepts1.ttl|wc -l

Note: only 83 RCs have rdfs:subClassOf umbel:FoodDrink. They vary a lot: rc:TastePerception, rc:NorthAmericanCuisine , rc:SpoiledFood, rc:SaltingFood (an activity), rc:TripleCremeCheese, rc:BasicVegetarianDiet

What does it apply to: Quote or WrittenWork

https://umbel.org/ is advertising some casinos. I guess it is no longer associated with this project.

This is the current content there:

Maybe consider getting an .eu.org domain instead, they are free and dont need renewal.

• change hasNationalArchivesIdentifier to sameAs
• change identifiedBy to dc:identifier, to fit common use

Sample API is not functioning

It seems that the umbel.org API has been down for a few weeks now. Is there a plan to continue maintaining the site?

dbpediaOntologyPages.n3 is subject to cut-down?

I've counted the RCs in two files at https://github.com/structureddynamics/UMBEL/blob/master/Named%20Entities/, and the correlation between them, using these commands:

cut -d " " -f3 dbpediaOntologyPages.n3 | perl -S prefixize.pl | sort | uniq -c > types.txt
cut -d " " -f 3 wikipediaCategoriesListsIndividuals.n3|perl -S prefixize.pl| sort | uniq -c > relatesTo.txt
join  -j 2 relatesTo.txt types.txt > relatesTo_types.txt

Results: https://gist.github.com/VladimirAlexiev/2510e8ea78aecda94dd6

• dbpediaOntologyPages has 896423 triples, using 184 different RC (lines in types.txt)
• wikipediaCategoriesListsIndividuals has 4395002 triples, using 1668 different RC (lines in relatesTo.txt)
• relatesTo_types.txt shows this correlation:
  96 common RC, 28% of the relatesTo triples and 57% of the type triples

Questions/problems:

• I see many counts in types.txt that are 10000 and 20000. I'm suspicious of such round numbers, is it possible that the mapping process has cut-down something?
• Isn't the correlation of types to relations too small? I'd have expected that each type also corresponds to a relation triple?

remove coatOfArms, has blazon

Maybe we don't need this since we have "blazon", which is used in some 200 templates:

Cound someone with knowledge of heralrdy tell us whether they are the same?
