A developer is creating an entity for home inspections that contains a field for the inspection date. Which configuration of the file name and the field name fulfills the requirement and follows best practices?
Guidewire ' s Metadata Naming Conventions are strictly enforced to ensure that customer code remains distinct from Guidewire ' s base product code, which is essential for seamless platform upgrades.
When creating a brand-new entity, the developer must use the .eti (Entity Interface) extension. Following Cloud Delivery Standards, the entity name itself must include the _Ext suffix. Therefore, HomeInspection_Ext.eti is the correct file structure. Regarding the fields within that custom entity, Guidewire best practices recommend applying the _Ext suffix to custom columns as well (Option B), even if the entity itself is custom. This provides a consistent visual indicator in Gosu code that the developer is interacting with an extension rather than a base product element.
Option A and C use the .etx extension, which is reserved for extending existing base entities (e.g., adding a field to Claim). Option D is incorrect because it lacks the mandatory suffix on the entity name. Option E uses an invalid file naming format. Following the convention in Option B ensures the data model is compliant with Guidewire ' s automated quality gates.
