Example Mapping Files

Within this part of the user documentation we have provided a wide array of sample mapping files to aid you in the creation of your own.

1 Page Structure
2 Example 1 - Simple CSV
3 Example 2 - Simple JSON
4 Example 3 - Simple XML
5 Example 4 - Simple SQL
6 Example 5 - Simple SQL with Query
7 Example 6 - Function within a Subject Map
8 Example 7 - Complex Embedded Functions

Page Structure

As with the Manually Create a Mapping File document, the examples will be clearly displayed using the following colour codes. Please note all Provenance Named Graphs have been omitted for simplicity and therefore the RDF output will be represented in NTtriples.

RML mapping files will be blue

Example input data will be yellow

Output RDF triples will be green

Example 1 - Simple CSV

id	name

id	name
10001	Alice
10002	Bob

Example 2 - Simple JSON

Example 3 - Simple XML

Example 4 - Simple SQL

id	firstname	lastname	occupation
10001	Alice	Johnson	Tech
10002	Bob	Smith	Sales

Example 5 - Simple SQL with Query

id	firstname	lastname	occupation
10001	Alice	Johnson	Tech
10002	Bob	Smith	Sales

Example 6 - Function within a Subject Map

id	name

id	name
10001	Alice
10002	Bob

Example 7 - Complex Embedded Functions

In this example we are using embedded function, functions within functions. We start with an if then else function where if the input contains the text “NIS“, split the input at the underscore (_), else split the input at the forward slash (/).
