Hello, I'm trying to automate metadata extraction in Alfresco Community 5.2 so that my custom models get populated automatically when documents are uploaded. My PDFs have custom embedded metadata fields (see image 1). However, when I import these PDFs to Alfresco, according to the information in the alfresco debugger, not all the metadata tags (for example prims: and jav:) are detected (see image 2). Do you know if this is the expected behaviour? In that case, what do I have to change so that Alfresco detects these custom metadata fields? Thank you very much for your help in advance.
