Ape version 0.7 is ready. There's something new for everyone: Ape now uses XML to configure mappers, gives other products an opportunity to enhance the mappers, periodically scans the filesystem for changes to cached objects, and if you like to ride the wild side, there's experimental code for storing properties using one table per class. Ape (short for Adaptable Persistence) adapts Zope objects to storage on the filesystem, in relational databases, or practically anywhere else. It combines the advantages of transparent object persistence with arbitrary databases and formats. It is especially designed to work with ZODB, but can work independently of both Zope and ZODB. Give it a spin. This is still an alpha release because there are some unstable APIs, but with help a beta could come soon. http://hathaway.freezope.org/Software/Ape Shane
