This extension detects and extracts metadata (EXIF / IPTC / XMP / ...) from potentially thousand different file types (such as MS Word/Powerpoint/Excel documents, PDF and images) and bring them automatically and natively to TYPO3 when uploading assets. Works with built-in PHP functions but takes advantage of Apache Tika and other external tools for enhanced metadata extraction.

For best results, Apache Tika <https://tika.apache.org/download.html>__ is
required (either as standalone JAR or running as server).
Extraction of metadata from common image files (jpg, tiff, ...) is often quicker
using external tool exiftool <https://exiftool.org/>__ and if not available,
it will fall back to PHP's built-in EXIF and IPTC library.
For PDF, external tool
pdfinfo <https://www.xpdfreader.com/pdfinfo-man.html>__ will be used.
