Hi, Seems I was misguided by your reference to IPropertyStore and Windows property handler. So my reply was based on that.
There indeed are PDF metadata firstly in document information directory for which there is PdfInfo class in podofo and secondly part in PDF metadata stream since PDF 1.4 which is stored as XML. XML from such PDF stream can be retrieved using podofo and then parsed by some XML parser like rapidxml. Although there probably is not direct method like GetMetadata in podofo but you would need to use lower level api and search for metadata streams as described in PDF Reference. These are distinct metadata than you would obtain using IPropertyStore. And are part of PDF file.
