Indexed Database API Draft Published

The Web Applications Working Group has published a Working Draft of Indexed Database API. User agents need to store large numbers of objects locally in order to satisfy off-line data requirements of Web applications. The Web Storage specification is useful for storing pairs of keys and their corresponding values. However, it does not provide in-order retrieval of keys, efficient searching over values, or storage of duplicate values for a key. The current specification provides a concrete API to perform advanced key-value data management that is at the heart of most sophisticated query processors. It does so by using transactional databases to store keys and their corresponding values (one or more per key), and providing a means of traversing keys in a deterministic order.
