A mapper is a software component that translates data between different formats, structures, or namespaces. In the context of namespaces, a mapper is used to map data from one namespace to another. A namespace is a container that holds a set of identifiers (such as variable names, function names, etc.) used to organize and differentiate elements in a software system. Mapping between namespaces is necessary when two different software systems use different namespace conventions or when there are conflicts between identifiers in different namespaces. Mappers can be created manually or using automated tools, such as code generators or transformation engines.
