I agree. The thing should be an LRMoo F5 Item :
Scope note: This class comprises physical objects (printed
books, scores, CDs, DVDs, CD-ROMS, etc.) that were produced by (P186i)
an industrial process involving a given instance of F3 Manifestation.
.......
Question: Are the sheets those actually bound, or are the bound pages
part of larger sheets? I assume the latter.
If we would do very analytical modelling of the processes, those sheets
would be the semi-finished product. Then, the final production process
would use the intermediate product. Sound unnecessarily clumsy.
If we in general infer the actual number of sheets from evidence in the
actual book, I think the Dimension is a good solution.
In LRMoo, the F3 Manifestation (former Manifestation Product Type) has
been generalized to the immaterial content including the intended
physical features. Then, the Dimension could go directly to F3, or a
new property "number of print sheets" would be needed.

First thing coming to my mind, assuming for instance it is “Yourbook” of 150 sheets:
introduce an E54 Dimension "number of sheets” and measure it
E70 Thing <“Yourbook”> (or whatever way you encode the physical book)
P43 has dimension
E54 Dimension <"Number of sheets">
P90 has value
E60 Number <150>
P91 has unit
E58 Measurement Unit <"Sheet number">
A bit verbose but you can extract & process directly the number of sheets,
select small books etc., calculate the printing cost etc
Note that P43 has domain E70 Thing so you can attach it to any subclass of
Thing / physical object you wish to use for the book. E-books may require
further work/different approach.
Obviously this refers to a specific paper edition, exactly “that" tangible
object, as a paperback may have a number of pages different from a hard-cover of the
same literary object.

Dear all,
I have a data modelling issue that I would like to discuss with you.
We have a database of books. Currently we are in the process of identifying,
for each book, the number of sheets used to print it. The number of sheets is a
good indication for the investment required to print a book. We want to store
this information in the database.
We do already capture the number of pages in the digitised copy as well as the
physical format of the book (using P43 has dimension on an F5 Item). We capture
data related to the printing of the book via a F3 Manifestation Product Type
and a F32 Carrier Production Event.
My intuition is that the number of sheets could be modelled as an E29 Design or
Procedure that P129 is about the F3 Manifestation Product Type.
But how to add the information "number of sheets" to the E29 Design?
Two thoughts:
- Simply as P3 has note: "20 sheets" (I would like it to be more machine
readable)
- as a P68 foresees use of E57 Material that P2 has type "sheet" (but where to
add the quantity of sheets?)
What do you think?
Best wishes,
Florian
