CDF is the catalog data format, the intelligent format for storing, distributing and using all contents of printed product catalogs together with an underlying database. The software product family of Clickcat is based on the CDF file format. Copyright for the CDF format is owned by Heinz-Geerd Neumann.
This software is based on the CDF technology, which is distributed by the HGN-Software Ltd. in London. Please refer for details to the web site of this software.
Contents of PDF files are first imported into the CDF format. Links are created in the CDF format, which is finally converted into HTML for use on the Internet.
There are specialized CDF reader software products available offering far more features than an Internet browser. But this is not the subject here, because this software covers the conversion of PDF to HTML only and not the use of CDF files.
