xdata is a set of shell-level utilities, and a perl module, which implement an interface to arbitrary key-value pairs which is accessible to simple shell and perl programs. Examples of applications for this include to-do lists, contact databases, browser bookmarks and so forth-- in fact, anything which requires small pieces of data to be referenced by keys. xdata stores timestamps for the data it manages, and comes with a program to synchronise databases among cooperating hosts. This allows you to propagate information among hosts in a transparent fashion (creations, updates and deletes are correctly handled), which is nice if you want to create a uniform environment on numerous machines.
xdata is free software, available under the terms of the GNU GPL.
