Data files are frequently uploaded from multiple sources. This example models a situation where two suppliers have uploaded spreadsheets into the metadata-injection-example/data/in folder.
When using metadata injection, you usually want to focus on a subset of data values common to all your input files. Metadata for the following values are used in this example:
- Transaction date
- Transaction invoice number
- Net value of the transaction
- Currency used in the transaction
The metadata for these values and the output target text file are created and maintained in the metadata-injection-example/metadata folder.
