Abstract: Embodiments of the present invention provide a method, system and computer program product for maintaining distributed state consistency in a distributed computing application. In an embodiment of the invention, a method for maintaining distributed state consistency in a distributed computing application can include registering a set of components of a distributed computing application, starting a transaction resulting in changes of state in different ones of the components in the registered set and determining in response to a conclusion of the transaction whether or not an inconsistency of state has arisen amongst the different components in the registered set in consequence of the changes of state in the different ones of the components in the registered set. If an inconsistency has arisen, each of the components in the registered set can be directed to rollback to a previously stored state. Otherwise a committal of state can be directed in each of the components in the registered set.

Abstract: Methods and apparatus, including computer products, for generating a natural language expression in response to a query. A computer-implemented method of generating a natural language expression in response to a query, includes generating a text frame from the query, and processing the text frame in conjunction with a grammar and one or more logic configuration files applied recursively to the text frame to generate the natural language expression from the query, the logic configuration files including functions that can pass arguments.
