[osis-core] references and self-ids Part 1 - Assumptions/statements

[Todd Tillinghast]

I have read through the Patrick's most recent posting as well as several
of the other postings.

Just to make sure we are all on the same page I put together the
following statements with I believe are TRUE and represent our intent
with respect to references.  If you don't believe any of these
statements to be true please post a response.
(I am using the term reference in the broadest sense to mean either self
identification or to mean an external reference that is either work
specific or work abstract.)
1) The simple part of the reference (ex Gen.1.1) has no meaning outside
of the context of at least a reference system.  
2) Whether validated or not a reference system defines the set of valid
references.
2) There may be zero or more specific works that are compliant with and
use a given reference system.  
3) In some cases a reference system and a specific work are equivalent,
either because a specific work defines the reference system or because
there is only one instance of the work.
4) It is possible to create a reference to a specific work using a
reference system that it does not support.  (The
translation/transformation would be left to software to resolve.)
5) Although a reference system is required, the specific work is
optional. 


It seems that we desire to do the following:
A) Self-identify text (mainly verses but also ranges of text, chapters,
and books).
B) Have the self-identifying identifiers be tied to a reference system
OR a reference system and a work without having to explicitly state the
reference system and work with each identifier.
C) Be able to self-identify text from more than one reference system
and/or work within a single document.
D) Create references (not self-identification).  
E) Create a reference to a range of text.
F) Describe a reference at greater granularity than the reference system
defines.  (grain)
