Introduction

The Mapper is a generic tool to map different datasets to a pre-established standard. It can be used to implement data interoperability solutions. The Mapper allows mapping columns and column values from files that contain data to be harmonised. Each file to be mapped contains data from one entity of the standard.

The application has three main functions:

1. Map attributes
2. Map attribute values
3. Save the map

The standard is expressed mainly with two files. One for the entities and attributes per entity and another for the attribute values. You can find an example here.
