Definitions for terms/concepts between product lines often vary. It would be great to be able to create a glossary/ubiquitous language archive where definitions can be linked to product lines or different products. This will help developers use business language in code, and foster understanding between stakeholders in different departments.
"administrator" in one product line may mean a sales partner versus "administrator" in another product line being someone in the marketing department.
"Username" in one product may have specific business rules versus "username" in another.
We use event storming / domain driven development so this would mean less static documents and more easy linking between ubiquitous language contexts.
Thank you for your idea. We would recommend creating a product note to store product or team-specific details such as these.
At this time, we are unlikely to implement this idea. We hope you can understand.
