This tutorial assumes at least some experience with Systems Modeling Language v1 (SysML^®). To learn SysML^® please attend our comprehensive course:

Course: Model-Based Systems Engineering with the OMG's Systems Modeling Language® (v1) and the SysML Plugin for MagicDraw® and Cameo™ (CATIA Magic)

This tutorial explains the theory behind the Webel Parsing Analysis recipe for SysML^®. This trail is a good introduction for the following complementary tutorial trails:

TRAIL: Webel SysML Parsing Analysis example: Optical telescopes from Wikipedia: Structure and port-based light flow model

TRAIL: Webel SysML Parsing Analysis example: A particle physics taxonomy from Wikipedia

In Webel Parsing Analysis tutorials, Wikipedia pages are often used as a placeholder sources to represent authoritative domain source documents from which text extract "snippets" are sourced, and from which SysML model elements are traceably elicited.

It may help if you've already explored the following section within the main Webel tutorial for SysMLv1.x, although most of the concepts covered there will be covered during this trail anyway (and in more detail):

18:01: Logical grouping with the ElementGroup extension of Comment in SysMLv1.x

We'll be referencing "super-relational" Policy Notes for the recipe as we go along, and we'll also be employing some of the more general Webel Best Practice modelling policies. Note especially that:

The Webel Parsing Analysis recipe for SysML1.x does not use the ElementGroup directly, it extends it as a user-defined Snippet stereotype with keyword «snippet» and with MagicDraw Customization.

Webel Parsing Analysis: typically the quoted extract text (body) of a «snippet» is a short phrase, a sentence, or a couple of short sentences (but not dozens of sentences).

For this relatively academic trail we'll be analysing first the following famous pangram:

Wikipedia: '"The quick brown fox jumps over the lazy dog" is an English-language pangram — a sentence that contains all of the letters of the English alphabet. '

«pa:term»: Dealing with synonyms, alternative names, and identifiers

«pa:triple»: Pseudo semantic triples (c.f. RDF/S and OWL)

A «pa:implied» Element: Include a tagged value for at least one Snippet that implies it

Indicating relationships between Snippets using tagged values: contradicts/contradictedBy

More on tracking contradictions: Optical telescope example

Webel Parsing Analysis as a meta-process: Snippets before Requirements!

Using Trace to quickly elicit model elements from an identified figure, drawing, diagram, plot, graphic, or table from a domain source document

Using a generic MagicDraw/Cameo query table to track /tracedTo for any NamedElement type using a derived relationship
