Title Big data interconnection peering mode
Figure
(optional)

As illustrated in the above figure, the following interactions are applicable:
a) Three data sources interchange directly with each other, and one of them is selected as primary
data source (e.g., data supplier (0)|BDSP (0)) as serving node to connect with the intermediator,
and the selected primary data source contributes all datasets or big data services' output from
data sources (e.g., both data supplier (0)|BDSP (0), data supplier (1)|BDSP (1) and data supplier
(2)|BDSP (2)) to the intermediator;
b) One data source is selected as primary data source, the other data sources are selected as
secondary data sources (e.g., data supplier (1)|BDSP (1) and data supplier (2)|BDSP (2)) by
default. The secondary data sources interchange datasets or big data services' output with the
primary data source on request in order to provide their datasets or big data services' output
via the primary data source to the intermediator;
c) The intermediator distributes the datasets or the big data services' output to the data targets
on request.
Pre-conditions a) There is a contract in place between the data sources (e.g., DP:data suppliers, DP:data brokers
(optional) or BDSPs) and the intermediator;
b) There is a contract in place between the data targets (e.g., BDCs) and the intermediator;
c) The intermediator is responsible for matching the purchase and sale contract between the data
sources and the data targets;
d) The data sources published the metadata and declared the copyrights, patents, licenses policies
and pricing policies and guaranteed the integrity, availability and authenticity of the datasets;
e) The data targets discovered the metadata and accepted the declared copyrights, patents,
licenses policies and pricing policies;
f) The data sources, the intermediator and the data targets complied with the business trade
agreement, and the intermediator matches the purchase and sale contracts when appropriate
between the data sources and the data targets.
Post- a) The interconnecting mode related transactions between the involved entities (data sources,
conditions intermediator, data targets) and the interconnected datasets or big data services' output should
(optional) be publicly published online and archived for monitoring online and auditing offline;
b) The interconnecting mode related transactions between the involved entities (data sources,
intermediator, data targets) and the interconnected datasets or big data services' output were
not repudiated.
