            Activities of big data service provider defined in [ITU-T Y.3600] are reused with modifications for big data
            exchange as follows:
            –       search data source;
            NOTE 1 – This activity is split from "searching data sources and collecting data by requesting and crawling" in
            [ITU-T Y.3600].
            –       collect data;
            NOTE 2 – This activity is split from "searching data sources and collecting data by requesting and crawling" in
            [ITU-T Y.3600].
            –       store data;

            NOTE 3 – This activity is renamed from "store data to data repository" in [ITU-T Y.3600].
            –       integrate data;
            NOTE 4 – This activity includes mash-up data on demand.
            –       provide tools for data analysis and visualization;
            NOTE 5 – This activity includes configuration of big data service from a BDC side; for example, modification
            of big data analyzing algorithms.
            –       manage data.
            NOTE 6 – This activity includes managing data quality, data provenance, protection of personal information,
            security, policy, ownership, licensing, etc.
            New activities of big data service provider as compared to [ITU-T Y.3600) include:
            –       offer auxiliary information: provide auxiliary information about a dataset or a big data service to
                    improve service utilization;
            NOTE 7 – Auxiliary information consists of statistics on summary of usage, data quality or data provenance,
            etc.
            –       deliver data and service's output: transfer either datasets or big data service's output.
            NOTE 8 – Data delivery methods depend on service context. BDSP can send data in real-time or by batch
            updates. Also, BDSP can use synchronous data transfer rather than asynchronous data transfer for time
            sensitive service.
            7.2.3   Big data service customer

            In the concept of big data exchange, the big data service customer is performed by the data target entity.
            Activities of big data service customer defined in [ITU-T Y.3600] are reused for big data exchange as follows:

            –       request big data service;
            NOTE 1 – This activity is renamed from "requesting big data services from the big data service provider" in
            [ITU-T Y.3600].

            –       use big data service;
            NOTE 2 – This activity is renamed from "use the output of big data services" in [ITU-T Y.3600].
            New activities of big data service customer as compared to [ITU-T Y.3600] include:
            –       provide feed-back on user experience: evaluate user experience on big data service.
            NOTE 3 – User experience includes service satisfaction or complaint, usage of service, etc.


            8       Functional requirements of big data exchange

            This clause describes the functional requirements of big data exchange.
