Re: [soa-rm] Related to Proposed Reorganization of Our Spec: SOA-RM "First-Class" Concepts
So you're creating the reference model for organizing the document and this can lead to multiple possible document organizations? Too many emails to too many BAH people. Night all.

So this analysis is simply an interim step on the way to my proposed new organization, and it may also be used to come up with alternate organizations as well (as I don't automatically assume that my proposed new organization will be adopted, of course).

True, there is usually a small number (relative to the total number of references) of "core" descriptions, but these may also be distributed so as to be explained in the appropriate place/context. This is not to say your analysis may not be valuable, but it may not in itself provide a satisfactory answer.

In order to get to that proposed new organization, I've decided to go through the entire spec and pull out what I would call "first-class" concepts whose discussion we may wish to consolidate into one section/subsection so that readers can jump right to those concepts (though I recognize that sometimes one needs to describe certain concepts in pieces). To that end, I've begun developing a list of "first-class" concepts - please see the analysis below (search on "ANALYSIS" - I've gone through half of the main part of the spec so far). In the analysis, I've basically reproduced each section/subsection heading, and listed groups of lines and what they cover. So for example, under Section 2.1 below you will see the following: <Quote> Lines 159-163: Visibility - Lines 161-163: Metadata, constraints, policy </Quote> This indicates that on lines 159-163, the "first-class" concept of "visibility" was discussed. Also, within that line range, on lines 161-163, the "first-class" concepts of "metadata", "constraints", and "policy" were discussed. I am being careful to use the same terminology throughout the list - i.e. always "policy", not "policy" sometimes and "policies" other times. What this will allow us to do, of course, is to take the information below and organize it by first-class concepts (perhaps in a spreadsheet), with the line numbers associated with each concept. Taking "metadata" as an example, in the information below we see that "metadata" is discussed on the following lines: - Lines 161-163 - Lines 163-164 - Line 179 - Lines 316-320 - Lines 341-345 This will also enable us to examine all of these occurrences and ensure that we speak consistently about metadata in each case (i.e. that there are no contradictions). So the analysis below is the interim step to arriving at this. I will also use these line numbers for the proposed new organization. Regarding the line numbers: I am using "an entire sentence" as the smallest reference. So if a sentence spans 3 lines, and there is a mention of a concept on the 2nd of those 3 lines, I list the range for all 3 lines. Please stay tuned for the final result (shortly)....
