As illustrated in the above figure, the following interactions occur:
a) The different data sources (e.g., data supplier (0), data supplier (1) or BDSP (S)) contribute
various big datasets or big data services' output (either homogenous or heterogeneous) to the
intermediator (e.g., data broker (I), data supplier (I) or BDSP (I)). When a data source (e.g., data
supplier (0)) has captured new datasets, it proactively notifies the intermediator and publishes
metadata (such as variety, classification, type, format, volume, value, velocity, veracity) and the
declared data rights information (such as copyrights, patents, licenses policies and price) of
these datasets or big data services' output to the intermediator;
b) When the intermediator receives notifications regarding published datasets, it registers the
corresponding metadata and declared data rights information for these datasets or big data
services' output, and (optionally) imports the relevant datasets or big data services' output from
the corresponding data sources and prepares for further distribution;
c) When a data target (e.g., BDC (0) or BDSP (T)) requests to access target data, the intermediator
(e.g., data broker (I)) searches the target big data services' output or datasets using the
metadata and the desired data rights in its local registry,
c.i) If more than one target big data services' output or datasets are found, the intermediator
(e.g., data broker (I)) further communicates with the corresponding data target (e.g., BDC (0) or
BDSP(T)) to distribute those target big data services' output or datasets to the data target.
c.ii) If none target big data services' output or datasets are found, the intermediator (e.g., data
broker (I)) attempts to discover the target big data services' output or datasets (using the
originally requested metadata and the desired data rights) in data sources (e.g., data supplier
(1) or BDSP (S));
d) When a data sources receives a request information from the intermediator (e.g., data broker
(I)), the data source searches target big data services' output or datasets, and returns the search
results to the intermediator (e.g., data broker (I)),
d.i) If no target big data services' output or datasets are found, the intermediator (e.g., data
broker (I)) notifies the data target (e.g., BDC (0)) that the request has failed, and;
d.ii) If more than one target big data services' output or datasets are found, the intermediator
(e.g., data broker (I)) further negotiates with the data target (e.g., BDC (0)) how to distribute
those target big data services' output or datasets (e.g., BDSP (S) or data supplier (1)) to the data
target (e.g., BDC (0) or BDSP (T));
