Tutorial
[TECHNICAL SLIDE TRAIL] The Webel libraries for Wolfram Mathematica: With SysMLv1 models.
Keywords
Please make sure you've read the intro page about this highly technical trail on the Webel libraries for the Wolfram Language and SysML4Mathematica.
This trail section is supported by the following Policy Notes, many of which are cross-referenced from the slides of this trail:
Mathematica: POLICY NOTES for the Webel Abstract Data Type (ADT) pseudo classes with inheritance for the Wolfram Language
Please keep the following in mind throughout this section:
Mathematica: Webel ADT: The term 'Abstract Data Types (ADT)' is used informally (the Webel ADTs do not always adhere to strict definitions of ADTs). Please just think of it here as meaning a strong type or stateless "pseudo class".
The following page provides some background and historical context (but it's best for now just to stick with this trail):
Dr Darren of Webel IT Australia makes the case for better object-orientation for Mathematica using pseudo class ADTs without losing the super-functional power of the Wolfram Language

Introduction to Webel Abstract Data Types (ADTs) with SysMLv1 models
Webel Abstract Data Types (ADTs) vs the user-contributed MTools for OO
Webel ADTs include inheritance (and aren’t actually formal ADTs)
Webel ADT hierarchy views as tree, graph, and SysML
Mini SysMLv1 BDD view of the Webel ADT Block
SysMLv1 Internal Block Diagram (IBD) of the Webel ADT base class
Webel ADT`package: Some ADT pseudo class utility functions in a ::usage help viewer. Diagnostic, help, and development functions.
Simple Webel ADT in the development view dV[adt] and class/methods help hC[adt]
Classes in the ADT` package: Extendable ADT pseudo classes have corresponding "definer functions"
Creating new ADTs that extend other classes using a definer function (and adt$addSuper)
Extending ADT sub-classes represented as SysML Blocks with redefined wrapped ‘$$’
Webel «adt:pseudo» elements in the SysMLv1 ADT model (1)
Webel «adt:pseudo» elements in the SysMLv1 ADT model (2)
Chained wrapped ADT pseudo Lists: Example: EX` package structured data ADTs
Chained wrapped ADT pseudos as a SysMLv1 Internal Block Diagram (IBD)
Clients of List ADTs don’t usually directly access the wrapped Lists (but can for testing with ADT⊙get which BREAKS ENCAPSULATION)
Webel ADT SysMLv1 Stereotypes
adt$graphHierarchy example: The EX` package for structured data
ADT finder functions and “methods” adt$findUp, adt$findUpArg, ADT⊙fM
ADT help functions and methods: adt$treeHierarchy (adt$tH), adt$hC, ADT⊙hC: Example: XL$Cell
ADT`: helpADT[class]: help on methods registered with HelpO`: Example: XL$Cell
adt$store, adt$fetch, and «adt:ref»: Example: Reference XL$ResourcesMap by ID in US$ResourcesHolder.

SECTION: Webel ADT case study: Extracting structured data from unstructured Open XML spreadsheet data
Mathematica: Webel ADT pseudo classes: There does not seem to be a way to register ::usage specific to a Webel ADT-Method (TagSetDelayed UpValue). The Webel libraries offer method documentation support via the HelpO` class/method registry.
Mathematica: Webel ADT pseudo classes: «adt:ref» applied to a property indicates that it is resolved by ID through the ADT store using adt$fetch[id]. Use adt$store[adt] for very large ADTs and for cleaner ADT views and easier Notebook development.
