Webel: SysML: "Really long human friendly element names with spaces make my diagrams easier to read". Dr Darren says "No they don't! Prefer code-like naming (or anonymous for typed elements) wherever possible. Use custom tagged values for other names!"
Webel: SysMLv1: Dr Darren for LinkedIn: On "Trusting The Type" and avoiding unnecessary verbose repetitive Property names ... unless you really, really need them and really do have reasons to use them, and then only use concise role indicators anyway!
Webel: SysML4Mathematica: Convention: A Mathematica Blank '_' (which pattern-matches any Expression) is represented by a custom SysML ValueType '_'
An Action may accept inputs and produce outputs, as specified by InputPins and OutputPins of the Action, respectively. Each Pin on an Action specifies the type and multiplicity for a specific input or output of that Action. Source Unified Modeling Language 2.5.1
A DataType may be parameterized, bound, and used as TemplateParameters. Source Unified Modeling Language 2.5.1
Instances of a structured DataType are considered to be equal if and only if the structure is the same and the values of the corresponding attributes are equal. Source Unified Modeling Language 2.5.1
If a DataType has attributes (i.e., Properties owned by it and in its namespace) it is called a structured DataType. Instances of a structured DataType contain attribute values matching its attributes. Source Unified Modeling Language 2.5.1
A DataType is a kind of Classifier. DataType differs from Class in that instances of a DataType are identified only by their value. All instances of a DataType with the same value are considered to be equal instances. Source Unified Modeling Language 2.5.1
A PrimitiveType defines a predefined DataType, without any substructure. A PrimitiveType may have algebra and operations defined outside of UML, for example, mathematically. Source Unified Modeling Language 2.5.1
Webel has a proposal for clearly revealing anonymous typed elements in SysML callouts and on derived Properties from operation queries.
DO NOT use Property names that are identical to the names of the Classifier (Class, DataType, Block, ValueType) that type them!
MagicDraw/Cameo: HOWTO redisplay the name and type of a SysML ItemFlow on a Connector if it vanishes (such as when the Connector is redrawn)
Port labels appear in the same format as properties on the end of an association. Port labels can appear inside port rectangles. Source OMG Systems Modeling Language (SysML) 1.6
If the property has no name, the property’s type name can be used instead. e.g., car:Engine:Cylinder:Piston.length car.e.c.p.length Source OMG Systems Modeling Language (SysML) 1.6
SysML: Typing a Port by an InterfaceBlock or ~InterfaceBlock does NOT imply that the Port is a ProxyPort (but ProxyPort must be typed by an InterfaceBlock or ~InterfaceBlock)
HSUV trail slide: Figure D.4: IBD: Could not show Connector typed by an anonymous Association as 'connectorName:' with trailing colon
SysML-1.6: For the Connectors in Figure D.4 to be typed by the implied anonymous Associations need define them in Figure D.15 (or elsewhere) between 'HybridSUV' and: 'Driver', 'Maintainer', 'Passenger', 'Baggage', 'Environment'.
Value types may be used to type properties, operation parameters, or potentially other elements within SysML. Source OMG Systems Modeling Language (SysML) 1.6
