A report protocol can further include one or more destination addresses, such as an IP address, MAC address, email address, web address (e.g., upload address), FTP address and so on. A report protocol may further include a report specification, which may indicate what type of data (e.g., composite-detection indication, particular composite values or processed versions thereof, data-source information, time and so on). Thus, in general, a report protocol may specify when a report protocol is to be implemented, a reporting condition, what to include in a report and where to send a report. It will be appreciated that a report protocol may include additional indications, such as composite-value constraints for applying the protocol (e.g., which may be identified based on input and/or association of a given user having provided an input), a type of transmission to send a report, and so on. By defining and using one or more report protocols, data systems can be improved to reliably detect and report key data.
