GB/T 34945-2017Information technology—Data provenance descriptive model (English PDF)

1 Scope

This standard defines a data traceability description model (hereinafter referred to ProVOC model, provenancevocabularymodel), Regulation

Describes the description of the ProVOC model component.

This standard applies to data collection, publishing, analysis and processing system designers and data users.

2 Terms and definitions

The following terms and definitions apply to this document.

3 ProVOC model review

The ProVOC model consists of three basic classes of data, activity and execution entities (hereafter called first-level classes). Data includes parameters and

The dataset consists of two sub-class components (hereinafter referred to as the second-level class component), where "parameter" includes three parameters of time parameter, spatial parameter and condition parameter

Type member (hereinafter referred to as a three-level member). The second-level component "data set" is closely related to the field of data traceability applications, and may be applied by specific applications

Areas are further broken down into sub-categories of three or more levels (specific data sets). Activities are initiated by the executing entity or controlled by the executing entity

One or a series of actions that affect. Execution entities include human execution entities (eg, people, organizations and companies) and non-human execution entities (Eg, services such as data provision). Human execution entities and non-human execution entities are secondary components of the execution entity.
