Thanks for the pointer. A colleague had already given me that hint and it worked fine.

Found it: The conversion code is implemented in ConvertXMLToJSON.class within /libs/fmdita/osgi-bundles/install/publish-workflow-4.2.jar. The XML-to-JSON conversion is done directly in Java, without XSLT.

I found some hints in the fmdita-publigh.log:*DEBUG* [sling-oak-observation-2] com.adobe.fmdita.publishworkflow.ConversionWorkflowsListener Resource change handler triggered for /content/dam/fmdita-outputs/json/testContent*DEBUG* [JobHandler: /var/workflow/instances/server0/publishditamap_491:/conte...

Hi Divraj,Thanks for this thorough explanation. I want to use AEM metadata in the JSON output but cannot figure out which DITA-OT plugin does the job. As far as I can see from the AEM log, the JSON generation is based on the "dita2dita" transformation from the org.dita.normalize DITA-OT plugin. But ...

I think I found the missing link in one of the posts by @DivrajSingh: 4) Enable the DITA-OT plugin to read the metadata and use itSource: Use AEM Metadata in DITA-OT PDF output There are indeed changes to a DITA-OT plugin necessary as already supposed. However, the example from Divraj is for the pdf...

Hi Aswini,Thanks for your quick reply. We did as you suggested but unfortunately the properties don't show in the JSON output. Do you perhaps have some sample JSON to see how this should look?Best regards,Frank 

Hello, We want to add Asset metadata that is attached to DITA files to the JSON output. We already pass the required metadata as properties to the DITA-OT. I suppose, including this metadata in the JSON output requires a DITA-OT plugin? If so, how would I implement this? Best regards,Frank

Hi Rohan,Great that you could fix this. A DITA map provides the structure of a DITA document whereas the DITA topics contain the actual content. A map without any referenced topic is basically an empty document from which you cannot create a PDF output.Best regards,Frank  

Hi Rohan,That could be a broken DITA file. Can you open the map and topics in Author or Preview view? If so, the files should be ok and the fault lies probably with the PDF generation. If not, check your files for broken DITA syntax.Hope that helps.Frank
