可视化编程语言的定义（如BPMN和LabView）

Question

I am looking for an exact definition for visual programming languages (VPL) which includes also a classification. I am of course aware of the Wiki page on VPLs but what I am after is a definition which includes classification by purpose, ideally with a reference to a publication.

Somehow (not perfectly) related websites and posts:

• Visual Programming Language Control
• Read LabView program without LabView
• Advantages and disadvantages of BPMN?
• Lecture on VPNs (unfortunately in German)

Answer 1

Probably Google's Blockly is what you are looking for. They provide very helpful publications regarding their product and VPL. From their publication

A Visual Programming Language (VPL) is a programming language that allows a user to create programs primarily through graphical manipulation. Some common interaction models in VPLs are:

• Dragging blocks around a screen (eg Scratch )

• Using flow diagrams, state diagrams, and other component wirings (eg Pure Data )

• Using icons or non-text representation (eg Kodu )

Hope this helps.
