[Crm-sig] representing textual phenomena

[Carlo Meghini]

Hi,

I'm working on the representation of literary works (LWs) using the CRM 
core and the LRMoo. I've made every LW, or any part of it, an instance 
of both E33_Linguistic_Object and F2_Expression. I'm interested in 
describing the syntactic structure of a LW, so by "part" I do not mean 
just chapters and sections, but also sentences, clauses, syntagmata and 
words; and I have compositional properties of coordination and 
subordination.

Now I need to describe the fact that any part of a LW occurs within the 
text in several segments (some sentences are in fact broken in 2, 3 or 
even 4 segments), and the position of each segment within the LW. This 
is very similary to the situation where there is a global event (such as 
the execution of a piano concerto) which has one sub-event (such as a 
specific instrument playing) occurring in several time intervals. The 
difference is that these occurrences are not in the relative time of the 
concerto, but in the relative space of a LW.

I've made these segments instance of class TextFragment, a subclass of 
E33 but not of F2 because a fragment may be as small as a word or two. 
The property linking a part to the text fragments where it occurs is 
called "occursIn". Now my first question is (assuming the modeling is 
ok), where should I hook such property in the CRM property taxonomy?

The property linking a text fragment to the actual text is 
P190_has_symbolic_content. I guess this is rather uncontroversial.

Finally, the position of each text fragment within the LW must be 
represented. This is done by using 2 properties, one for the beginning 
and one for the ending of the fragment. The value of each property is a 
position within the text. A position, in turn, is identified by 2 
coordinates: the content unit where it occurs (e.g., chapter) and by a 
number giving the offset within the content unit. Final question: where 
would position, begining and ending position belong in the CRM?

Thank you for your time.

Carlo
