According this scenario, how can I specify that Hominide is a Primate and Canidae is a Carnivora? Should exist the terms Primate and Carnivora in Ontology B and C, respectively, in order to add the is-a relationship from Hominide to Primate and from Canidae to Carnivora
The easiest way would be to add A as an import in B and C, this way your B or C ontology would be aware of the extern terms from A.
Could I write is-a relations to terms that are not included in the current ontology?
Yes you can, but you have to make sure the identifiers resolve correctly. For instance, if you have ontology A in http://example.com/a
and ontology B in http://example.com/b
, you'd add the following to your ontology B:
[Term]
id: http://example.com/b#Hominide
is_a: http://example.com/a#Primate
Or, with an ID space to avoid repeating yourself:
idspace: B http://example.com/b#
idspace: A http://example.com/a#
[Term]
id: B:Hominide
is_a: A:Primate
Thanks for your answer, @althonos. I think I get it now.

Hi all, I am dealing with a problem in obo regarding the use of external terms. In my case, I have an ontology that contains upper level terms, on one hand, and another ontology that has more concrete terms, on the other hand. I will show this situation with the following taxonomic example:
In this example Ontology A contains the upper elements of a taxonomic hierarchy, which includes from Animalia to Primate and Carnivora. Then, I have Ontology B keeping the hierarchy for primates and Ontology B keeping the hierarchy for carnivora.
According this scenario, how can I specify that Hominide is a Primate and Canidae is a Carnivora? Should exist the terms Primate and Carnivora in Ontology B and C, respectively, in order to add the is-a relationship from Hominide to Primate and from Canidae to Carnivora? Could I write is-a relations to terms that are not included in the current ontology?
I know that in RDF you only have to include the triple
hild owl:subClassOf parent
and parent could not be present, but I am not sure about obo.I would like to be as obo compliant as I can.
Thanks for your time, Francisco Abad.
