        Data providing service definition, concept, and use-cases


  The standard defines terminologies and describes ecosystem for data
  providing service. In order to build unified data environment from the
  dispersed data, data providing service is necessary for big data 
  service. Therefore, this standard contributes to form common data 
  providing ecosystem.

1. Introduction

  This standard proposes concept, definition, and use-case of data 
  providing service for big data service. First, the scope and 
  definition of data providing service are described. Second, ecosystem
  model and role classification are illustrated. Finally, use-cases for
  explaining data providing service are proposed.

2. Terminologies
2.1  Data generator
  The data generator generates data, provides metadata to data broker, 
  and provides API to the data refiner to access data.

2.2  Data broker
  The data broker brokerages data between the data generator and the 
  data customer.

2.3  Data refiner
  The data refiner refines data, which is from the data generator, and
  delivers data to the data customer.

2.4  Data customer
  The data customer uses data, which is provided by the data providing

3. Abbreviation

4. Overview of data providing service 
4.1. Concept of data providing service
  Data is dispersed in different administration domain. For this reason,
  it is hard to search data in big data area, which highly needs data.
  This situation decreases the data availability. In order to increase 
  the data availability, an interface is needed to brokerage data in
  different administartion domain and to search data in single access
  point. For example, a user finds data which is in different
  administration domain, while it is still hard to use the data. That is
  because data type and access methods are different. A data customer 
  uses different methods to access data, and also the data may have 
  different type, so that a data customer does extra works, such as 
  converting, filtering. Thus, an interface is required to refine data
  in various administration domain in order to provide the customized
