 We have been using Protobuf as more than just a serialization mechanism from the very beginning. It provides a language to model the domain. This ability is especially useful in projects based on the [Domain-Driven Design](https://martinfowler.com/bliki/DomainDrivenDesign.html) methodology, aka DDD.
 
-The defining feature of a Domain Model is the [Ubiquitous Language](https://martinfowler.com/bliki/UbiquitousLanguage.htmls) — a language that is used and agreed upon throughout the domain: by the domain experts, programmers, and in the code. A Domain Model consists of many components, but the language lays the base for all of them. Value Objects help up transform the language into code.

 ## What are Value Objects?
 A Value Object is a simple type that represents any kind of logically indivisible domain information, such as `EmailAddress`, `PhoneNumber`, `LocalDateTime`, `Money`, etc. Unlike Entities, Value Objects are only identified by the value itself, i.e. they do not have a designated ID. These objects are immutable and, typically, not too big. Apart from the encapsulation of the data itself, such types can hold the validation logic, basic operations on the data, the string representation, etc. For example, the type `LocalDateTime` may provide methods such as `add(Duration)` which calculates the local date and time after a given duration passes. The result is another instance of `LocalDateTime`, while the original object is unchanged.
