There are three levels of importance in pitfalls according to their impact on the ontology:

Critical It is crucial to correct the pitfall. Otherwise, it could affect the ontology consistency, reasoning, applicability, etc.
Important Though not critical for ontology function, it is important to correct this type of pitfall.
Minor It is not really a problem, but by correcting it we will make the ontology nicer.

Pitfalls detected:

It refers to reusing or referring to terms from another namespace that are not defined in such namespace. This is an undesirable situation as no information can be retrieved when looking up those undefined terms. This pitfall is related to the Linked Data publishing guidelines provided in [11]: "Only define new terms in a namespace that you control" and to the guidelines provided in [5].

• This pitfall appears in the following elements:
› http://www.w3.org/2002/07/owl#Prefix
› http://www.w3.org/2002/07/owl#Import

• For detecting this pitfall we rely on TripleChecker. See more results at TripleChecker website. Up to now this pitfall is only available for the "Scanner by URI" option.

Suggestions or warnings:
