The fundamental principles have new context.    (02)

Data issues are longer nascent and somewhat lost is marketing babble 
spewed by DBMS vendors. My data and applications that help me work with 
my data are too distinct things. The need to loosely couple Data and 
Applications (including DBMS engines) was so clear in the past.    (03)

Due to the evolution that's occurred in our innovation continuum.    (05)

Of course! At least that's what I hope.    (07)

Yes, of course.

Yes. Likewise, I prefer our conceptual graph notations to those used by 
the W3C. For instance, you don't make the mistake of using literals to 
denote relations which ultimately ensures confusion.    (010)

[subject]-->--(relation)--->---[object]    (011)

Is much clearer than:    (012)

[subject] -- predicate --> [object]    (013)

No disagreement. They all benefit from the incorporation of URIs that 
enable data representation to become web-like.    (015)

Yes, and I've never (and never will) disagree with that.

Software exhibiting those characteristics are the exception rather than 
the norm. Most are just the result of hard-nosed-lock-in by vendors 
especially RDBMS vendors :-(    (017)
