    Leave this window, if you close it you'll stop the GUI process.

  4. If this software does not open then you may not have Java installed on your computer, or you may have an incompatible version of Java installed on your computer. (Please go to the section ‘Installing Java on a PC’ for help.)

  5. You can check what metadata extractors (HUL modules) are installed by selecting the ‘Help’ menu and ‘About JHOVE’.

  6. This will open a new window. JHOVE works by incorporating different ‘HUL’ modules that extract metadata from different types of files. Each of the HUL modules represents a different set of common file types (e.g. PDFs) that it can extract metadata from.
