[Crm-sig] Fwd: Re: Issue 383 Homework, addition

Dear All,

Continuing the question from my last message below:

Very large strings one would normally describe in a file and instantiate 
E90 Symbolic Object or a subclass of it with the URL. However, the 
question is, if the URL would indeed be a good persistent identifier, 
since the URL stands for a physical location, albeit indirectly 
addressed. The Linked Open Data community has not yet given satisfactory 
answers for the long term validity of resolvable URIs. If the URL is not 
a good identifier, another, primary URI should be chosen, and the 
content found in the URL should be related to the primary URI as a 
representative of the content of the symbolic object identified with the 
primary URI.

I would like to discuss a new property,

PXXX has content representation
domain: E90 Symbolic Object
range:     E90 Symbolic Object

Tentative scope note:
Scope note: This property associates an instance of E90 Symbolic Object 
with another instance of E90 Symbolic Object (or any of its subclasses) 
that represents completely the content of the former identically 
concerning the the symbol set  in which the former is defined and 
nothing more. For instance, a text of Aristotle may be defined in terms 
of the ancient Greek alphabet, paragraphs and section titles, but the 
representing object may use some type phases and page layout. Metadata 
in the range instance are not regarded as part of the content.

What about introductions, foot notes etc.?

Can someone make a scenario with a real canonical instance of a text of 
Aristotle or Platon, with indexed phrases, and propose how the text 
itself should be identified, possibly independent from spelling variants?

Another case: I submit to Springer a paper in .doc and they create a 
pdf, and a Journal image. How do we define "my paper" regardless these 

In the worst case, we would need yet another node in order to specify 
the part of the file that is the defining text.

Further, P165 incorporates is from information object to symbolic 
object, hence not compatible.

Another argument being, that an ontological link from E90 to E90 doesn't 
make sense. If the target should be a URL, we may regard this as an 
implementation level question.
