Figure 7-2 – An example scenario of cloud computing support for big data
NOTE – Figure 7-2 considers cloud service categories based on Table A.1 of ITU-T Y.3500.
7.1.1 CSN:data provider (CSN:DP)
CSN:data provider (CSN:DP) is the sub-role of the cloud service partner (CSN) generating and publishing new
data or information which feeds into the big data system for discovery, access and transformation. The
CSP:data provider's activities include a generate data activity, a publish data activity and a brokerage data
activity.
7.1.1.1 Generate data activity
The generate data activity involves gathering data from several kinds of sources. The data can be generated
in a variety of types such as structured data, semi-structured data and unstructured data.
The data sources include public data (data from governments, organizations, Internet, etc.),
private/enterprise data and application based data, such as social network service (SNS) and Internet of
Things (IoT) data.
7.1.1.2 Publish data activity
The publish data activity is the process of registering metadata of data to the CSN. It provides metadata for
brokerage data activity.
NOTE – metadata is delivered to the CSP:BDIP through brokerage data (see clause 7.1.1.3) with the data
catalogue which includes data access methods, data use policy, etc.
7.1.1.3 Brokerage data activity
The brokerage data activity involves providing metadata of data to the CSP: BDIP.
Types of brokerage data activities include:
– providing a data registry to the CSN:DP for publishing their data sources;
– finding an on-line data source and registering its metadata;
– providing a catalogue to the CSP:BDIP for searching appropriate data.
