Peereflits.Shared.Types

This library/package contains types that behave like (domain-driven-design) primitive types. These types contain self-contained rules, behaviors and data and have no external dependencies.

This library contains the following types:

• AGB code (an identifying key of Dutch healthcare providers)
• BSN number (a Dutch social-security number)
• E-mail address
• IBAN number
• Mime types
• Phone number (Dutch- and international phone numbers)

Rules for adding new types

Before adding new types, keep the following rules in mind:

• This library MUST ONLY contain types that have the exact same meaning among other projects/solutions¹.
• This library MUST have no dependencies (.NET BCL only).
  1. As a result this library should also be usable in Blazor.
• This library CAN be shared/used among all other projects.
• This library SHOULD only contain concrete types; no interfaces.
• All types in this library SHOULD behave as "immutable types".
• All types in this library MUST be under unit tests.

As a general rule:

• types that have the same name, meaning and behavior both inside and outside an organization are likely to be good candidates;
• types defined by external institutions or organizations² are good candidates.

¹⁾ A type such as "Customer number" should therefore not occur, as different definitions (format, length, use) can live within different projects (and organisations).
²⁾ For example: ISO with "country" and its ISO country code
