Abstract

The invention provides a data product metadata providing device and method, and the device comprises a user interaction module which is used for receiving data demand information inputted according to a preset field requirement; the data product description module is used for describing the data product by utilizing the hierarchical associated polymorphic information and matching the data demand information with the hierarchical associated polymorphic information to determine port information of the data product; the user interaction module is also used for acquiring and outputting data product metadata according to the port information; wherein the predetermined field requirement is determined according to the polymorphic information associated with the hierarchy; wherein the element type of the polymorphic information comprises data provider information; wherein under the condition that the product form of the data product is a data file or a data source service, the polymorphic information comprises field value coefficients, and the sum of all the field value coefficients in the polymorphic information meets a set standard. Through the scheme, data product transaction can be facilitated.

Description

technical field [0001] The present invention relates to the technical field of data services, in particular to a data product metadata providing device and method. Background technique [0002] In the Internet-based data circulation market, data resources mainly exist in five product forms: data terminals, data files, data source services, information authentication services, and data processing services. Because these product forms have different requirements on the technical capabilities, transaction methods, usage methods, and scope of use of both parties, some product forms are suitable for one-to-one personalized transactions, and some are suitable for large-scale market-oriented operations. Among them, the three product forms of data files, data source services, and information authentication services are suitable for standardized, large-scale, and open market-oriented operations. [0003] There is currently no way to relate to the description of data products. For t...
