– big data service provider #A imports raw data from data suppliers, processes these raw data and
outputs processed data. Big data service provider #A exports either raw data and/or processed data
to big data service provider #B and/or exports processed data to big data service customer;
– big data service provider #B imports raw data and/or processed data from big data service provider
#A. Big data service provider #B makes use of these imported data;
– big data service customer imports processed data from big data service provider #A and makes use
of these imported data.

NOTE 2 – Although not shown in the figure, data supplier is a sub-role of data provider as per [ITU-T Y.3600].
NOTE 3 – Big data service providers in big data exchange expose the availability of processing capabilities and
export the captured, collected, prepared, analysed and visualized data to big data service customers on
demand.

7 Framework of big data exchange

This clause describes the framework of big data exchange including further details on the two major big data
exchange patterns introduced in clause 6 and the description of additional activities to the ones defined [ITU-
T Y.3600].

7.1 Patterns of big data exchange

7.1.1 Direct exchange pattern
A direct exchange pattern is represented by a primitive model (see clause 6.2), which means it is composed
of interactions between a data source and a data target. In the big data ecosystem, there are three types of
interaction scenarios available for the direct exchange pattern as shown in Figure 7-1.

Figure 7-1 – Direct exchange

The three interaction scenarios of direct exchange pattern are as follow:
1) EXSC: Supplying | collecting big data (Data supplier → Big data service provider): a data supplier
provides datasets to a big data service provider by using on-line or off-line methods, and big data
service provider uses them;
2) EXIW: Interworking big data service (Big data service provider → Big data service provider): a big data
service provider uses big data service's output from a peer big data service provider;
