After a definition of the general terms and types of metadata, this White Paper lists which metadata appear in Microsoft Office files. The main part of the document concentrates on metadata in PDF files, i.e. on general data and on data imported from Office documents, including some examples on the direct comparison of the conversion input and its result. Finally, some information on the presentation/display of metadata in PDFs and on data removal from Office files is available.



The White Paper starts with a short introduction into the PDF format and its general advantages. Then, a detailed description of the special advantages and requirements of PDF server solutions follows. Next come the alternative ways how PDF files may be created and distributed in networks. Finally the document gives an insight into a possible solution, PDF Render Center.



Forms standardise the written communication between the participating persons, companies, institutions and public authorities. Nowadays, electronic forms in the shape of PDF files are commonly used. This White Paper discusses the following topics: basic considerations about the use of forms, electronic forms and their advantages, form requirements, basics about PDF forms, the structure of PDF forms, forms design, FDF files (Forms Data Format), XFA forms, filling and using forms.



PDF Xpansion is the soft Xpansion PDF technology. Its implementation in a form of PDF SDK is for software developers intended. Using this solution software developers can integrate all important PDF functions into their own applications. The SDK can be used in business as well as in consumer products. The actual version of PDF Xpansion is based on the Adobe® PDF Specification 1.7 and allows the solution of almost all PDF-related tasks (creation, displaying, editing, signing, etc.) including bidirectional conversion between different file formats on the on side and PDF files on the other side.

This guide illustrates the basics and advantages of the Adobe® Portable Document Format (PDF), the version history, the requirements and scope of different PDF Xpansion generations, gives recommendations and hints for releasing PDF SDK, explains the license model and outlines the included samples.



The server-based creation of PDF documents and documents in other formats requires first of all a centralized conversion with the help of a PDF printer. But the following efficient distribution of the created documents to the respective receivers is at least just as important. The source documents should be sent by the clients to the so called Render Center. The converted documents, e.g. PDF or TIFF files, should be sent back to the author or other persons or places. Network printers, FTP servers, TCP/IP protocol, e-mail sending, websites and/or virtual drives can be used for the distribution.

This article presents an according solution using the example of PDF Render Center. The kernel of this application is a Windows system service, a virtual PDF printer and an administration program for the settings.



Smart cards are small computers, integrated into a plastic card. Confidential information can be saved on the card and protected against the unauthorised access. The data saved in the micro chip of the card is usually more complex to be read as e.g. from the hard disc of a computer. This feature qualifies smart cards for a lot of interesting applications, e.g. a two-factor authentification for the enhancement of the access control methods. This article describes the basics, practical application areas, the application of smart cards in lending processes and in thin client solutions in the context of two-factor authentification. Besides, a small glossary of the important terms is included.



Digital signatures provide a safe and legally binding digital communication (e.g. via e-mail). But how should a digital signature be formed? How can a company achieve, that the receivers of digital documents - e.g. PDF files - can trust these documents as well as traditional paper documents? This article describes the requirements and methods.
