     Data providing service requirements and functional architecture


   The standard describes concept and characteristics of data providing
   service. To derive functional architecture, requirements are described
   on the perspective of providing and using data.

1. Introduction
   Unstructured data is continuously increased from IoT devices such as
   smart phones, tablets, and wearable devices with mobile and social 
   network services (SNS). With increasing of unstructured data, Big 
   data services have been already appeared to drive the traditional
   process-oriented computing paradigm to data-centric computing
   paradigm. In data centric computing environment, Data Providing
   System might be realized by core technology. In this circumstance, 
   the importance of data providing has emerged. 
   In order to provide data, these various data need to be provisioned
   with low complexity and high availability. Provisioned data can be 
   provided to data users by user's requests. Moreover, the environment
   which data users can search data is necessary. This environment might 
   contribute to form a virtuous circle which shared data is used to   
   create new service. Therefore, this standard defines data providing 
   service requirements and functional architecture to support data 
   management and accessibility.

2. Terms and Abbreviation

   - DG : Data Generator
   - DB : Data Broker
   - DR : Data Refiner
   - DPS : Data Providing Service
   - DC : Data Customer

3. Data Providing Service Requirements

   Data providing service can be divided into 3 parts : data management,
   data policy management, and data provision. Requirements condition is
   as follows :
      - M : Mandatory
      - R : Recommended
      - O : Optional

3.1 Data Management Requirements
   In table 3-1, requirements of data generator(DG) and data broker(DB)
   is defined for data management.
