A schema-based notification/alert service for providing schema-based notifications. The notification service includes a schema that defines rules and a structure for sending, handling and/or receiving notifications and alerts. Senders and receivers manipulate (e.g., read or write) data in the logical document by data access requests through defined methods. In one implementation, the notification schemas are arranged as XML documents, and the services provide methods that control access to the data based on the requesting user's identification, defined role and scope for that role. Extensibility is defined into the schema. An architecture is provided to intelligently route alerts from senders to client user agent recipients.
