1. A system enabling interactive integration of network-accessible applications in a content aggregation framework environment, comprising: a computer comprising a processor; and instructions which are executable, using the processor, to implement functions comprising: receiving, by a component that mediates access to a network-accessible application in the content aggregation framework environment, a response message from the network-accessible application, the response message comprising a first portion containing at least one data value to be published to a brokering mechanism and a second portion containing content requested by the mediating component from the network-accessible application in a request message, wherein the content contained in the second portion is to be forwarded to a content aggregator for aggregating into a content view along with content provided by one or more other components; forwarding, by the mediating component, the content contained in the second portion to the content aggregator for the aggregating into the content view along with the content provided by at least one of the one or more other components; and responsive to detecting, by the mediating component, the at least one data value in the first portion, publishing each of the at least one data value in the first portion to the brokering mechanism, thereby enabling each published data value to be automatically shared with any of the other components which have ability to consume the data value from the brokering mechanism.
