Abstract: Embodiments described herein allow a service component author to write service components without having to handle incoming messages being received at any time. This may be facilitated by a message dispatch engine that dispatches messages from the incoming message queue only when the destination service component has indicated that it is ready to receive the message having that context. If the service component is not yet ready for the message, the message dispatch component may lock the message at least until the destination service component indicates that it is now ready to receive the message. Until that time, the message dispatch engine may ignore the locked message when finding messages to dispatch.

Abstract: Technologies for conversations between various parties, the conversations including context information that can be persisted to maintain the conversation when the parties or the communications media they communicate over operate intermittently. In such a conversation, any party can embed its view of the context into a message and any party can send the next message regardless of role and regardless of the underlying network, transport, or application message exchange pattern. Such technologies provide for durable services.

Abstract: Changes are managed in a multi-user database application environment. Proposed changes are collected, including changes to data, schema, and/or application descriptions. A user may specify foreign key relationships between items belonging to one or more of these categories. A view is produced showing the impact proposed changes would have on the environment if successfully committed. The user's proposed changes are ordered according to their dependencies, and submitted for committal together in a single transaction, subject to optimistic concurrency and consistency checks. For example, a proposed change to a data value may be inconsistent with a change which removed a data element containing the data value. The commitment operation may return identifiers and other return values, in addition to indicating whether the commitment was successful.

Abstract: User experience in a designer tool manages cogeneration of a database application and a database accessible through the application. A user places a visual representation of an application element designed to control a relational or hierarchical dataset. Code is automatically called to add the application element to the application, and automatically invoked to create database schema elements designed to implement the dataset in the database under application element control. Users verify that an application element has been automatically added, and confirm that database schema elements implementing the dataset(s) under control of the application element have been automatically created. A tutorial illustrates a workflow utilizing a designer tool to cogenerate a database application and a database without a data design step. A wizard utilizes the designer tool to cogenerate a database application and a database that collectively implement a calendar, a diagram, a tree, a wiki, and/or a list.

Abstract: A distributed security system is provided. The distributed security system uses a security policy that is written in a policy language that is transport and security protocol independent as well as independent of cryptographic technologies. This security policy can be expressed using the language to create different security components allowing for greater scalability and flexibility. By abstracting underlying protocols and technologies, multiple environments and platforms can be supported.

Abstract: A system for aggregating context information for messages includes a context container that associates names with context values and metadata for context entries. The system further includes a network protocol component configured to read messages from a network transport, an encoder component configured translate messages from a raw format into a canonical message format. The canonical message format is an enveloped message containing an application payload and message metadata. The context container is associated with a message in the canonical format. The system further includes an extraction component configured to retrieve context from a native network transport protocol and insert the context values and metadata into the context container, a plurality of additional protocol components configured to add, remove, or modify entries in the context container, and one or more higher level application components configured to operate on the canonical message using the context entries.

Abstract: The present invention extends utilizing abstract descriptions to generate, exchange, and configure service and client runtimes. A computer system parses compiled code and potentially optional configuration information for implementing a service and converts the compiled code and any configuration information into an abstract service description. The abstract service description can then be converted into code document object model and service configuration information or exported as metadata. A corresponding service runtime can be initiated by calling a service initializer included in the abstract service description. The code document object model and configuration information and/or metadata can be transferred to another computer system. The other computer system can utilize the code document object model and configuration information and/or import the metadata to facilitate initialization of a compatible channel for communicating with the service runtime.

Abstract: The present invention provides for an automated, user friendly way of constructing and using a binding object. A developer is presented with and selects binding elements that will ultimately be used to create a runtime communication channel for transporting a message between a client and service endpoint. After receiving the user input, metadata, a channel factory and listener factory are created. The metadata describes binding elements and provides an abstract representation of a protocol stack that implements communication aspects at runtime. The channel factory is configured to use the collection of metadata at runtime to generate the runtime communication channel. Further, the listener factory is configured to accept the runtime communication channel for de-multiplexing the communication aspects in order to process the message at a service endpoint. The present invention also provides for groupings of binding elements and standardized binding objects organized based on industry need.

Abstract: Methods and systems for providing a virtual network are disclosed. At least one layer of abstraction is created between network service applications and conventional network protocols by inserting an adaptive dispatcher between applications and network transport services on each machine in a network. The message protocol in the virtual network is extensible, allowing application programs to create new headers within any message as needed. The adaptive dispatcher contains handlers that route and dispatch messages within the virtual network based on arbitrary content within each message, including any combination of headers and/or data content. Each device on the virtual network has a virtual address to which messages are directed, allowing devices to move within the network without reconfiguring routing tables.

Abstract: Described is a data model used in a continuation based runtime that executes activities. The data model provides for declaring parameters to define data flow direction (in, out or both in and out) with respect to activities. The model further allows for the declaring of variables to provide for data storing and sharing between activities that are in scope, based on a tree relationship between activities. In one aspect, an activity tree includes a topmost parent composite activity and at least one child activity of that topmost parent composite activity. Variables are associated with one or more composite activities of the tree, and the ancestral relationships between composite activities and (non-composite) child activities determine the in-scope access to variables. Arguments such as binding expressions may bind variables to an activity's parameters.

Abstract: An environment for developing clientside/serverside code is disclosed. The environment supports programming in an event-driven paradigm while the execution of the resultant programs are executed in a serial execution paradigm. Through shielding the developer from complex scripting segments, the environment provides the developer with the suggestion that that resultant execution model is event-driven.
