A Word About Terminology
This change was to disambiguate the Xpress Insight term from the notion of a FICO® Decision Optimizer project. FICO® Decision Optimizer is a specialized Xpress Insight app layered above (and dependent upon) an installation of Xpress Insight.
While this guide and all related Xpress Insight documentation refers to apps throughout, for compatibility, there are developer-specific usages of project. Specifically, the APIs have not been updated and you will see references to JavaScript functions such as getProject() rather than getApp(). The same is true of references to file system entities, hence you might also see references to the project-icon.png file.
System authorities related to app permissions have been cosmetically changed in the user interface, but the underlying names remain unchanged. Thus the authority concerning app deletion is actually called PROJECT_DELETE, and this is how you should refer to it in code, even though if you were to examine the Admin user interface, it would appear to be called APP_DELETE. Note that this only applies to authorities defined by Xpress Insight itself—those defined by users or apps are unaffected.
