XMP, or Extensible Metadata Platform, acts like a digital label embedded within PDFs, carrying information beyond the document itself. It holds details like author names, creation dates, keywords, and even revision history. Programmatically extracting this XMP data unlocks a treasure trove of possibilities. Imagine automatically organizing PDFs based on author or keyword, extracting copyright information for legal purposes, or even tracing the evolution of a document through its XMP timestamps. This power makes XMP extraction invaluable for researchers, librarians, and anyone who wants to squeeze the most out of their PDF collection.
Several .NET Core PDF components support the extraction of XMP metadata including:
- Aspose.PDF for .NET is an advanced library for PDF manipulation, including XMP metadata extraction and editing capabilities that works in .NET Core.
- DevExpress PDF Document API (part of DevExpress Office File API) includes a PdfDocument.Metadata property which allows you to access a document's metadata.
- ImageGear for .NET by Accusoft is an powerful document processing toolkit featuring XMP metadata extraction options as well as text extraction for .NET Core use cases.
- Document Solutions for PDF by MESCIUS (formerly GrapeCity) is a specialized PDF library enabling seamless XMP metadata access and manipulation in .NET Core environments.
