Subject: RE: [Non-DoD Source] Re: [cti] The Adaptive Object-Model Architectural Style


CLASSIFICATION: UNCLASSIFIED 

Hi I am new to this committee.  I am very interested in the progress of this set of standards and am going to try to jump in to make a contribution.

Based on below, I agree with all comments as they each have merit, but I mostly agree that simple description and approaches should be used first.  

I am seeing comments that suggest this domain is difficult; ref: "Our standard has a lot that's hard to explain" and " dealing with a complex domain".  I do believe there are concepts and abstracts that will be tough to deal with but we should explicitly lay out what those complexities are; we may just find that they are not as complex as rumored.  They are rumors or speculative until we document them.  By documenting the complex abstracts and subsequently solving them, we will also reduce the chances that the domain will generally always be viewed or perceived as a complex domain, just because it has always been stated as such.

Documenting the challenging portions will also enable us to gauge our own abilities to deal with them correctly.  In turn, we may seek additional knowledge or support to tackle the challenges or we realize it is not as difficult as perceived.

V/R
- James

sorry for the others if off-topic.

Remember that a software is good only if it satisfies the users (meet, or exceed, their requirements).
You can write 'perfect/optimized' code. If the users are not satisfied; it's a bad software.

Then,
"If you can't explain it simply, you don't understand it well enough.", Albert Einstein

Challenges are exciting, but sometimes difficult. It's about motivation and satisfaction.

There is not programming language better than an other (just like OS); it is just you that can select the best for your needs.

I did a conceptual map for the 'biggest Ruby project of the internet'
(Metasploit Framework), it's just a picture, but represents 100 pages of documentation.
I think we could optimize (like for a maturity model) our approach of resolving problems.

I've learned that writing code--while applying KISS, DRY and YAGNI--saves me from entering the architecture stratosphere. That's why I ask the architects to express their creations in code, and not only in UML.

But this principal applies in any language: If the implementation is hard to explain, it's a bad idea. (Another quote from the Zen of Python.) Our standard has a lot that's hard to explain, esp. to new-comers. How can we simplify, so that it's almost a no-brainer to adopt?

>> Jerome,

>> On Page 20, the section "Maintaining the Model" [1] states pretty clearly that this type of architecture is very unwieldy, from an end-user perspective; consequently, it requires a ton of tooling development.

>>
>> If I were given the choice between (1) a very simple data model that's not extensible, but clear and easy to approach and (2) a generic, extensible data model whose extra layers of indirection make it hard to find the actual data, I'd gladly choose the first.

>> [1] The full wording from "Maintaining the Model":
>> The observation model is able to store all the metadata using a

>> programming tools to assist users with using these black-box 
>> components [18]. This is part of the evolutionary process of Adaptive 
>> Object-Models as they are in a sense, “Black-Box” frameworks, and as 
>> they mature, they need editors and other support tools to aid in describing and maintaining the business rules.
