Load a file to examine Get a collection of PropertyDescriptor instances for any desired metadata package Iterate through the extracted descriptors advanced_usage.GettingKnownPropertyDescriptors
try (Metadata metadata = new Metadata(Constants.InputDoc)) { WordProcessingRootPackage root = metadata.getRootPackageGeneric(); for (PropertyDescriptor descriptor : root.getDocumentProperties().getKnowPropertyDescriptors()) { System.out.println(descriptor.getName()); System.out.println(descriptor.getType()); System.out.println(descriptor.getAccessLevel()); for (PropertyTag tag : descriptor.getTags()) { System.out.println(tag); } System.out.println(); } } Note Not all possible properties are presented in the getKnowPropertyDescriptors collection....metadata of PDF, DOC, DOCX, PPT, PPTX, XLS, XLSX, emails, images...
