Abstract: 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.

Abstract: Described is a schema-based notification platform that provides regularized notification handling including user control and normalization of the operation of policies across different information types and contexts. Information-service schemas and services are combined to build a content-sensitive and context-sensitive information service to communicate information to recipient devices of users that subscribe to those services. An information agent service collects the information, and based on various criteria, determines if, when, and how to send and render the information, and to which subscribing client device or devices. The set of schemas include a notification schema that represents the subscription of a service to an information source and details about that information, and a device schema that represents information about user devices.

Abstract: A schema-based inbox service that provides Internet access to per-user inbox data, (e.g., name, address, telephone numbers and e-mail addresses), wherein access to the inbox data is based on each user's identity. The inbox service includes a schema that defines rules and a structure for each user's data, and also includes methods that provide access to the data in a defined way. The inbox schema thus corresponds to a logical document containing the data for each user. The user manipulates (e.g., reads or writes) data in the logical document by data access requests through defined methods. In one implementation, the inbox 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. In this way, data can be accessed by its owner, and shared to an extent determined by the owner.

Abstract: A schema-based presence service for Internet access to per-user presence data, wherein access to data is based on each user's identity. The presence service includes a schema that defines rules and a structure for each user's data, and also includes methods that provide access to the data in a defined way. The presence schema thus corresponds to a logical document containing the data for each user. The user manipulates (e.g., reads or writes) data in the logical document by data access requests through defined methods. In one implementation, the presence 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. In this way, data can be accessed by its owner, and shared to an extent determined by the owner.

Abstract: The method and system for limiting the number of installations of a computer software program located on a read only disk from the read only disk to a computer. The read only disk is linked to a removable read/write memory by data on the removable read/write memory corresponding to data on the read only disk. Prior to installation of the computer software program from the read only disk to the computer, software residing on the removable read/write memory determines whether the installation is authorized. Such determination is made by comparing identification information corresponding to computers on to which the computer software program has previously been installed to installation limitations dictated by a software license agreement.
