org.apache.stanbol.entityhub.servicesapi.model.Text
Defines a natural language text in a given language.
The text MUST NOT be null nor an empty {@link String}. The language may be null (indicating the default language) or any kind of value. It is recommended to use ISO 639-1 codes (two Letter codes). By definition it is also allowed to use empty strings as language. However implementations of this interface are free to convert the empty language to null.
Implementations of that interface MUST BE immutable @author Rupert Westenthaler
