Does anyone have thoughts on the best way to store metadata for a file? For example; owner, last modified, etc.
So far my thoughts have been a large table serialise to a file for storage after a shutdown that would be put into memory on boot.
My other thought was to store it within the file name as a serialised table and modify the fs api to unserialize it to get the data and the actual file name.
Anyone else have thoughts?

Well file name one sounds problematic due to fact that some symbols are not allowed in file-names and they may exist in meta-data.
Personally would go with one big file updated every time data changes instead of shutdown cause you can't detect all shutdown types.

That is what I had meant, save it on change rather than before shutdown.

It's not only a good solution - it's being used by other programs already.
