XSpace Description

Free and open source hierarchical data repository XSpace is a repository for hierarchically-keyed information, easily accessible from anywhere by any application that allows you to store just about anything in an XSpace – XML documents, strings, serialized objects and URIs. Think of an XSpace as a kind of hash table, globally accessible, where the keys have a hierarchical naming syntax (e.g. “/a/b/c”).XSpace supports real-time events; whenever a keyed value is added, updated or deleted from an XSpace, an application is informed of the event. XSpace lets you perform search starting from any node in the hierarchy.XSpace is targeted for use by collaborative components within an application and across applications where information needs to be shared. For example, you can use XSpace to:· store for information for content management systems.· store configuration information used and managed by different applications.· store catalog information organized by hierarchical categories.· store access control information for users within hierarchical organizations.· act as a “white-board” for a group of collaborative applications.Installation instructions for XSpace can be found here.NOTE: XSpace is licensed and distributed under the terms of the GNU Library or Lesser General Public License (LGPL).
