Here is a simple tool designed for managing your .oiv package files. You can use this to easily create and/ or modify archives that use .oiv format 2.0. I put this together since it can be quite a tedious process to put the archives together manually. Using this tool you can create an archive in less than 30 seconds (:

Using the tool is very simple:
To create a new .oiv package file:
1. Enter all desired metadata on the metadata tab
2. Use the add content wizard on the content tab to add files to the archive
3. Save the package to .oiv format on the import/ export tab

To open an existing .oiv package file:
1. Use the import existing package function on the import/ export tab
Future versions should include support for any updates to the .oiv format. In the meantime please report any bugs that you find with the current version!
