I am not following close enough the discussion on subjects as literals , and
whtere they contribute
to the awkwardness of RDF

One thing I remember finding it disorienting though, is that there is no
rule that a predicate must be a verb
(when I was looking at triple as if it were a subject- predicate- object
model )

In standard modelling practices  (E/R modeling) the relations tend to be
verbs

I did bring this up on another list, and the engineers thought it would be
good practice to
restrict predicates to verbs for obvious reasons (obvious to anyone who does
data models)

Not sure how that would play if RDF is shown as  EAV (entity attribute
value) rather thant SPO (subject predicate object)

Just thought I d mention this, in case someone wants to fix RDF thats the
first crack I spottend a while back

cheers
