Abstract: Methods, systems, and computer program products for applying actions during server system processing. Functional processing blocks where actions may be applied to a service request are identified. actions are dynamically associated with functional processing blocks. During execution of a functional processing block, a check is performed to determine whether an action is associated with the functional processing block. If an action is associated with a functional processing block, the action is applied during the functional processing block's execution. An evaluation may be performed to determine if an action should be applied before or after the functional processing block. The server system may comprise an XML data repository, providing access to XML data, based on identity information which is received with a client system request. A portion of the server system may be described in accordance with an XML schema.

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: Described is a schema-based context service that provides regularized context data, such as to an information agent that handles notifications. The context service and context schema describe user contextual state data, including presence information, location information, and schedule information, along with people and groups data, sensor data, computing context data and/or extended-context data. The state data may be obtained via similar schema based services.

Abstract: Profile controls for profiling a distributed application are included in messages that are also used by the distributed application to transport data. A profile initiator causes profile controls to be inserted in the header portion of a message that is being transported across a distributed system. The profile initiator may insert profile controls directly or may cause a message router that receives the message to merge profile controls into the message. The message router may receive profile controls from the profile initiator or from computer-readable media that are maintained at the message router. The message, which now includes distributed application data and profile controls, is routed to a message recipient. The message recipient accesses the message to identify profile actions that are to be performed at the message recipient. The message recipient performs at least one of the identified profile actions.

Abstract: A client sends a message to a server computer system over a network. Upon receiving the message either from the client or from a local process, the server passes the message down through a software stack to a lower layer module that is capable of detecting errors in the message. That lower layer module then detects an error and inserts error information that represents the error into an error reporting data structure. The lower layer also inserts potential text remedy information on how to correct the error. The module that detected the error then returns and passes the error reporting data structure back up through the software stack. The server then sends the response to the message along with the text field that includes the text error information back to the client computing system or other local requesting process.

Abstract: Methods, systems, and computer program products for accessing data where the data store provider is abstracted from both the data manipulation language used to access the data and the schema that describes the data. A received request structured in accordance with the data manipulation language is represented in an intermediate form. From the intermediate representation, a native request for any of one or more data store providers may be produced. Before being returned to the requestor, a native response from data store provider may be formatted so that it is structured in accordance with the data manipulation language used for the request. A given request received by one computer system may cause a procedure to be generated for accessing the data store provider. When a later request is received by second computer system, the previously generated stored procedure may be reused if applicable.

Abstract: A client sends a request to an authentication server requesting access to a service at an application server. The authentication server returns a token containing an encrypted version of a session key that was encrypted using a secret shared between the authentication server and the application server. The client encrypts application data using a corresponding unencrypted version of the session key and text-encodes both the encrypted application data and the encrypted version of the session key. The text-encoded application and text-encoded encrypted version of the session key are both included in a message and sent to the application server. The application server decrypts the encrypted version of the session key using the shared secret so as to reveal the unencrypted version of the session key. The application server then decrypts the encrypted application data using the revealed unencrypted version of the session key.

Abstract: Methods, systems, and computer program products for converting a single expression referencing multiple branches within a hierarchical schema into multiple expressions referencing a single branch of the hierarchical schema. The single expression includes expression components that identify branches within the hierarchical schema. Relative to a given branch, any branches referenced by a given expression component are identified. The identified branches are stored as new branches. If no branch is identified, the current branch may be removed as inconsistent. Storage for current branches is cleared, the new branches are copied to the current branches, and the process is repeated for each expression component. An expression component may include a predicate for determining which branches are referenced. The predicate may include predicate expressions that are converted to predicate branches and the predicate may include predicate operators.

Abstract: Authorizing a requesting entity to have a service perform a particular action in a manner that is at least partially independent of the underlying target data structure. An authorization station maintains a number of role templates that each define basic access permissions with respect to a number of command methods. The authorization station also maintains a number of role definitions that each define access permissions for specific requesting entities by using one or more of the role templates. When the authorization station receives a request from the requesting entity, the authorization station then identifies the appropriate role definition. Using this role definition, the authorization station determines access permissions for the requesting entity with respect to the requested action.

Abstract: A schema-based device service that provides centralized access to per-user device data, wherein access to the device data is based on each user's identity. The device 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 device schema thus corresponds to a logical document containing the data for each user. A service such as a notification/alerts service accesses data in the logical document by data access requests through defined methods, such as in order to customize or modify a notification for a device based on the device characteristics. In one implementation, the device 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.

Abstract: Information exchange among non-networked devices is disclosed. The information exchange occurs through instantaneous networks, like piconets, established between the non-networked devices and an intermediary device. For example, the intermediary device receives information from a first device during a piconet including it and the first device. This piconet dissipates, and another piconet is established between the intermediary device and a second device. During this piconet, the intermediary provides the information it received from the first device to the second device. The second device has received information from the first device, even though these devices have not networked themselves in an ad hoc network like a piconet or a scatternet.

Abstract: Directly operating on data structures in a generic manner regardless of the type of data structure being operated upon and without requiring dedicated executable code for manipulating data structures of the particular data type. A common set of commands (e.g., insert, delete, replace, update, query) are recognized that may be used to operate on data structures of a number of different data types. A navigation module accesses a request to execute one of the common command methods on at least an identified portion of an identified data structure. Then, the navigation module accesses a navigation assistance module to access a set of rules associated with the particular data type, the set of rules allowing the navigation module to find the portion of the data structure that is to be operated on. If appropriate, the command operation is then executed on the identified portion of the data structure.
