Document communication runtime interfaces

A server for providing document communication runtime interfaces, the server comprising:

• a memory storing instructions;
• and
• a processor coupled to the memory, the processor executing a hosted service in conjunction with the instructions stored in the memory, wherein the processor is adapted to:
• facilitate document-centric messaging for transmitting calls supporting a script object model;
• provide security employing at least one of a policy checking mechanism over the messaging, wherein a receiving entity confirms whether a transmitting entity is allowed to transmit a call, and a sandbox process to manage extension content traffic between an application hosting a document and third party web services providing the extension content;
• provide a solution manager to determine which extensions relate to an instance of the application, a document content type, and document content, and to obtain configuration and policy information from manifest files cached on a user machine;
• monitor aspects of the extensions;
• stop or restart the extensions based on violations of predefined metrics;
• provide a background thread in a rich client application for managing an interaction with a runtime environment by queuing requests and interacting with a foreground user interface thread;
• and
• provide a cross-document messaging based API in a browser-based application that securely exchanges requests between an iframe hosting the runtime environment and one of an iframe and a page hosting a document.

A computer-readable memory device with instructions stored thereon for providing document communication runtime interfaces, the instructions comprising:

• facilitating document-centric messaging for transmitting calls supporting a script object model;
• providing security employing at least one of a policy checking mechanism over the messaging, wherein a receiving entity confirms whether a transmitting entity is allowed to transmit a call, and a sandbox process to manage extension content traffic between an application hosting a document and third party web services providing the extension content;
• providing a solution manager to determine which extensions relate to an instance of the application, a document content type, and document content, and to obtain configuration and policy information from manifest files cached on a user machine;
• monitoring aspects of the extensions;
• one of stopping and restarting the extensions based on violations of predefined metrics;
• providing requests through a process to a rich client application for managing an interaction with a runtime environment without impacting a user experience;
• and
• providing a cross-document messaging based API in a browser-based application that securely exchanges requests between an iframe hosting the runtime environment and one of an iframe and a page hosting a document.
