Methods, systems, and computer program products are provided for delivering dynamic media content to collaborators. Embodiments include providing collaborative event media content, wherein the collaborative event media content includes a grammar and a structured document; providing data identifying a client's location; storing, in the context server in a data structure comprising a dynamic client context for the client, the data identifying the client's location; detecting an event in dependence upon the dynamic client context; identifying one or more collaborators in dependence upon the dynamic client context and the event; and selecting from the structured document a classified structural element in dependence upon an event type and a collaborator classification; and transmitting the selected structural element to the collaborator. In many embodiments, detecting an event in dependence upon the dynamic client context includes detecting a change in a value of a data element in the dynamic client context, and applying event detection rules base to the dynamic client context.
