Data Distribution System --> Other Data Distribution Systems:
data query
This triple is bi-directional. See also
Other Data Distribution Systems --> Data Distribution System: data query
Definitions
data query (Information Flow): Data query includes those dialogs necessary to determine what data is available for and also submit a query for near-term response.
Data Distribution System (Source Physical Object): The 'Data Distribution System' collects, processes, and distributes ITS data, connecting data producers with data consumers and facilitating data exchange.
Other Data Distribution Systems (Destination Physical Object): Representing another Data Distribution System, 'Other Data Distribution Systems' is intended to provide a source and destination for information exchange between peer (e.g. inter-regional) data distribution systems. It supports modeling of projects or regions that include multiple interconnected data distribution systems that together manage data distribution in the connected vehicle environment.

Interoperability | Description |
---|---|
Regional | Interoperability throughout the geopolitical region is highly desirable, but if implemented differently in different transportation management jurisdictions, significant benefits will still accrue in each jurisdiction. Regardless, this Information Flow Triple should be implemented consistently within a transportation jurisdiction (i.e., the scope of a regional architecture). |

Corruption of this flow could have a significant impact on data reception; however, re-query should be a fairly simply process, justifying MODERATE and not HIGH. | Query flows need some level of abailability; if the flow is not satisifed the user may be become frustrated and seek a solution other than DDS. Thus MODERATE. |
