The Repository and the Transfrom Service T-Router reads the configuration from T-Engines and then their own pipeline files. The T-Engine order is based on the <engineName> and the pipeline file order is based on the filenames. As sorting is alphanumeric, you may wish to consider using a fixed length numeric prefix.
For example:
localTransform.imagemagick.url=http://localhost:8091/ localTransform.libreoffice.url=http://localhost:8092/ localTransform.misc.url=http://localhost:8094/ localTransform.pdfrenderer.url=http://localhost:8090/ localTransform.tika.url=http://localhost:8093/ shared/classes/alfresco/extension/transform/pipelines/0100-basePipelines.json shared/classes/alfresco/extension/transform/pipelines/0200-a-cutdown-libreoffice.json
The following sections describe ways to modify the configuration that has already been read. This may be added to T-Engine or pipeline files.
