An industrial integrated development environment (IDE) supports open or extensible application programming interfaces (APIs) that enable end users (e.g., plant asset owners, original equipment manufacturers (OEM), system integrators, etc.) to build upon the IDE's development platform to create custom views or to code custom functionality. This can include, for example, defining a control programming syntax supported by the industrial IDE, customizing a development environment view afforded by the IDE's interface, modifying or creating project editing functions, defining customized programming guardrails designed to guide compliance with in-house programming standards, or other such IDE customizations.
