My company uses a proprietary file format for some of its data processing. The file format is not associated with a given application like a .docx file would be for MS Word and the content may or may not be printable. We are currently using LiveCycle to provide document access via PKI, but would like to extend LiveCycle to support our proprietary format as well. Is LiveCycle extensible in this way? If so, what documentation would our software development team need to learn how to do this?
