TRAIL: The Webel SysMLv1 Pattern for Digital Twinning

Webel Parsing Analysis: The name of a Parsing Analysis Diagram (PAD) may be drawn from a focus Snippet OR may simply indicate a topic of interest to the analysis

Webel Parsing Analysis: Where too many dashed line "anchors" from Snippets to elicited members lead to clutter they may be selectively omitted from a Parsing Analysis Diagram (PAD) once each member has been collected.

Webel Parsing Analysis: While Associations may be collected as elicited members of a Snippet this can quickly lead to clutter in the /member list display. Often just collecting an end Property as member is sufficient.

Webel Parsing Analysis: While Generalizations may be collected as elicited members of a Snippet this can quickly lead to clutter in the /member list display.

Webel Parsing Analysis: A "focus" Parsing Analysis Diagram (PAD) for one or more Snippets SHOULD always show the /member tagged value of every Snippet.

Webel Parsing Analysis: A Parsing Analysis Container MAY collect any other Element type as a member EXCEPT for another Parsing Analysis Container

Webel Parsing Analysis: A Parsing Analysis Container MAY own other child Parsing Analysis Containers

Webel Parsing Analysis: The symbol for a Parsing Analysis Container MUST be able to indicate the unique domain source document from which its analysed text extract was quoted.

Webel Parsing Analysis: It SHOULD be possible to relate one Parsing Analysis Container to another and stereotype that relationship as an RDF/OWL-like semantic triple

Webel Parsing Analysis: It MUST be possible to collect elicited members of a Parsing Analysis Container graphically in diagrams using relationship-like path drawing (not just via a specification dialog or other indirect modelling means)

Webel Parsing Analysis: The symbol for the relationship between a Parsing Analysis Container and elicited model elements SHOULD be a dashed line (like the anchor/handle line used with a UML Comment)

Webel Parsing Analysis: The symbol for a Parsing Analysis Container MUST be text-friendly and evocative of quoting a domain source text extract

Webel Parsing Analysis: The symbol of a Parsing Analysis Container MUST be usable on every possible diagram type

Webel Parsing Analysis: A Parsing Analysis Container MUST NOT be able to own the Elements it elicits

SysMLv1.x: Q: Why can't a Package with PackageImports be used as a Parsing Analysis text container? Why is the SysML1.6 ElementGroup (extended and customised as the Webel «snippet») far better suited for text-driven model element elicitation?

In some slides some Comments in UML/SysML diagrams are verbosely marked with the stereotype keyword «webel» to distinguish them from «snippet» domain source document text extracts.

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

Webel Parsing Analysis: SysMLv1.x: Q: "Instead of using a Snippet extension of an ElementGroup, can't I just use a Requirement and Trace to achieve the same thing?" A: No! The ElementGroup extended as the Snippet is far more powerful and fit for purpose.

Webel Parsing Analysis diagrams do their job once - namely traceable elicitation of model elements - and are then only kept as a reference! The elicited model elements are then used elsewhere in the final model.

TRAIL: Webel's ultimate guide to Systems Modeling Language (v1) with MagicDraw/Cameo

Webel Parsing Analysis (with strict traceability of all elicited model elements) can be used side-by-side with "freestyle" modelling with incremental benefit the more it is used.

The Webel Parsing Analysis recipe promotes a clearly scoped modelling workflow.

Even relatively informal elicitation of model elements using the SysML ElementGroup and a Parsing Analysis approach is extremely powerful.

Translating authoritative technical documents written in “natural” engineering language (snippet-by-snippet) into Webel Parsing Analysis diagrams creates consistent underlying systems models and can bridge easily to existing methodologies.

Humans work well with natural language: Many stakeholders – including those who are not necessarily familiar with UML or SysML modelling symbols and diagrams - benefit enormously from having plain text in diagrams side-by-side with graphics.

Webel Parsing Analysis: A Snippet (keyword «snippet») MUST always have exactly one domain 'source' Document (keyword «document»).

Webel Parsing Analysis: A custom Document stereotype (keyword «document») extends the UML standard profile Document that extends Artifact (which is NOT in the UML4SysML intersection). Such a Document may act as the 'source' of a «snippet».

Webel Parsing Analysis: Create a top-level 'source' or '0-source' Package/Model SEPARATE from your project model. All source «document» elements and «snippet» extracts and «pa» diagrams MUST be ultimately owned by that top-level Package/Model as ancestor!

Webel Parsing Analysis: If you are processing lots of text from one source «document» create a STUB «snippet» with that «document» set as 'source' and just make copies of it in the model browser as needed. Big time saver!
