File Content Extraction 25.4
Filter SDK C++ Programming Guide

# metadata

Some file formats contain additional documentation (metadata) about document contents. This sample program makes use of the `metadata_map` API method to provide metadata fields and values.

The fields that are present vary depending on file type and the individual document. For example, running the sample program on a PDF file produces output similar to the following:

    $ ./metadata KeyView_11.0_OS3P.pdf
