PDF document processor SDK from RasterEdge is a professional PDF component package that covers all the aspects of PDF document manipulations in .NET Framework application, like creating, viewing, saving, editing, annotating and handling.

The term metadata can be literally interpreted as "data about data". In PDF document imaging applications, metadata can be used as a useful method to provide additional information about the PDF document, such as the information about PDF document author, PDF publication date and copyright restrictions.

RasterEdge XDoc.PDF SDK for .NET supplies optimized standards-based PDF document metadata processing technologies. C#.NET developers can easily integrate this PDF document metadata manipulating control into their professional PDF document content management system, which can not only allow developers and end-users to edit PDF document metadata but also permit them to have an extensive search for encoded metadata based on certain parameters.
