The problem is that the AbstractSwordInstaller sits over top of mods.d.tar.gz, which it does not unpack. Instead, it iterates over all the entries in that binary file and handles each entry (i.e. a conf) in core. It doesn’t hit the disk. I’m wondering whether it would be alright to unpack the file in the same folder? That would allow a SwordBookMetaData to reload the file.

My ideas aren’t good enough to be put into practice, but some kind of flag indicating empty, partially or fully loaded. Empty would mean that it hasn’t gone to disk to get the conf. Partial means that it read everything, but threw away most as not interesting (since the conf does not have order you have to read and parse it all). Full would mean that nothing was pitched. SwordBookMetaData.getProperty would need to be changed to determine whether the key is in memory or might be on disk and do the right thing.
