Hi Adam,

among things being already posted, you may also try:
- BDB which is a very, very small wrapper of Berkeley DB (http:// www.sleepycat.com/). Berkeley DB is very useful e.g. for storing BLOBS in btree- or hash map- like structures. The implementation of BDB covers only a small set of functions. But with these functions it is quite possible to use HashMap or BTrees in conjunction with objects conformin to NSCoding.

- FT. If you somehow want to relate blobs thus forming somehow a graph then FT might be interesting for you.
    FT is based on BDB.

FT and BDB can be found at

Does anybody know of a "CoreData" like methodology that works for 10.3 as well?

What I'm looking for is a way to store a fair amount of persistent application data (Cocoa objects) into a database (binary file) on quit and retrieve it again on launch... I would love to use CoreData as that's what it's for, but I would like to support 10.3 as well... This could also probably be achieved by NSArchiving to a Plist but it seems like it's stretching their intended usage a little.

I think I could probably roll my own given enough time, but support could be difficult as I don't have a 10.3 machine handy any more :)
