I'd like to think that ontology-building started more or less as data 
modeling;  however, in the context of AI where the Gruber's use of the 
term 'ontology' is rooted^1, agents are supposed to be intelligent, as 
opposed to dumb databases, and their data are representations of their 
reality, and thus 'ontology' sounds better than mere 'data model'. 
(Note, this is my pure speculation.)    (03)

I have heard many times that XML schemas are not ontologies, they are 
data models.  Well;  the data in a particular XML document are real, and 
the schema that the document is valid against is an ontology -- it 
represents that bit of reality where the document belongs.  (Not that I 
will furiously defend this terminological experiment.)    (04)

^1 He was not the first to use it;  wikipedia says, "Although not the 
first to mention the word "ontology" in computer science (that 
distinction belongs to John McCarthy), Hayes was one of the first to 
actually do it.")    (05)
