The Kala Basket: A Semantic Primitive Unifying Object Transactions, Access Control, Versions, and Configurations

Abstract

Kala is an untyped persistent store for practical object-based systems, such as OODBMS, OMS, and object-oriented languages with persistence.Baskets are dynamic groupings of immutable data elements managed by Kala.Baskets synthesize transaction, configuration management, and access control semantics, and thus offer a platform for implementing arbitrary such models.In this article we introduce Kala baskets, their design motivations and goals.We then explain Kala's basket mechanism in some detail.Finally, we offer a few examples of how baskets are used to implement features of arbitrary transaction, configuration, and access models.
