Every approach to transform metadata with metafacture is quite similiar:

• You need to know the type and source of the input and the type and destination of the output: e.g. Transform data from Marc21 from a certain folder to some kind of JSON Data.
• You have to identify the commands that you need.
• Combine the commands without the transformation module and test if the workflow goes through.
• Adjust the workflow until it works.
• If the general workflow is working, move on to prepare the transformation.
• Get familar with the incoming data:
  • e.g. use | list-fix-paths| print to checkout the metadata-element paths that are provided.
  • use | list-fix-values ("specifiedElementPath")| print to get all element values of a certain element
• Start to write your transformation successivly and write to a specific destination or print the result.
• Start with one element that you want to transform and retain it.
• If you are happy with the result continue.
• If you have finalized your transformation include it in your application or transform the data you want for single reuse.
