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: An anonymous Element may be collected as a /member of a Snippet (it is not important whether collected elements list with a clear name under /member, only that they are traceably elicited).

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: Acronym: PAD = Parsing Analysis Diagram (may be nearly any diagram type, except those types that must be owned by an elicited model element)

Webel Parsing Analysis: As StateMachine Diagrams are always owned by an element that is not eventually under the Source Input Zone they should not be used as «pa» diagrams. Elicit States instead via the /member section of the specification dialog.

Webel Parsing Analysis: The absolute basics of the process (SysMLv1.x form)

SysMLv2: On the v2 Comment extension of the v2 AnnotatingElement as a candidate Parsing Analysis Container

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?

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.

SysML Block Definition Diagram (BDD)

In Webel Parsing Analysis elicited model elements MUST eventually be moved out of the 'source' (or '0-source') Package/Model zone and under a main project Package/Model area. (Use the owner display option to check.)

In Webel Parsing Analysis every Package, Model, or Diagram used to perform Parsing Analysis MUST have the stereotype keyword «pa» applied, and MUST live under a top-level Model or Package 'source' separate from the rest of the project model.

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.

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.

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 «pa» Parsing Analysis Diagrams (PADs) are "scratchpads" used to elicit model elements traceably from text Snippets (extracts from source Documents). While BDDs are a good initial choice, most types of SysML diagram can be used as a «pa» diagram.

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!

Webel Parsing Analysis: If you wish to show a «snippet» comment symbol (with its body text) in a presentation diagram (that is NOT a «pa» diagram) remove the '/member' tagged value from display so the only visible tagged value is 'source'.

Webel Parsing Analysis «pa» diagrams are NOT intended as final presentation diagrams! They serve merely to traceably elicit model elements, which may then be shown in other (typically much tidier) presentation diagrams elsewhere.
