Extensible framework for executable annotations in electronic content

Insertion of an executable command or instructions in the form of an annotation to electronic content, such that the receiver can benefit from a more precise and detailed context as they interpret and/or act on the sender's request. The system can, upon detecting an appropriate trigger, be configured to 'translate' or convert the annotation across multiple applications and platforms and perform one or more tasks that facilitate the receiver's access to and interaction with the item. The sender enjoys a much finer control over the manner, presentation, and overall context of the electronic content item as it is shared, and becomes able to offer the receiver a more precise understanding of their own intentions in sharing this item. Similarly, a receiver can be guided toward actions or responses that are expected or desired by the receipt of the electronic content item.
