Detailed Description

In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The terms first, second and the like in the description and in the claims and in the above-described figures are used for distinguishing between different objects and not necessarily for describing a sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, apparatus, article, or article that comprises a list of steps or elements is not limited to only those listed but may optionally include other steps or elements not listed or inherent to such process, method, article, or article.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the invention. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

The metadata can be used for describing the attribute or state of the target data, and the quality of the metadata needs to be monitored in the running process of software or projects, so that the data quality and the change condition of the metadata are mastered in real time. However, in the existing metadata quality determining method, corresponding process documents are filled in when metadata is changed in a manual mode, and the data quality is ensured through manual verification. However, the process document of metadata change may relate to a lot of contents to be copied and pasted, and when the change range is large, time is wasted and mistakes are easy to occur, meanwhile, the understanding and the detail degree of rules in manual auditing are different from person to person, and the auditing result is easy to deviate. Therefore, the metadata quality determining method has low efficiency and accuracy of metadata quality determination due to low standardization, so that the standardization of metadata quality determination is very important.

According to the method provided by the application, a series of process documents can be generated according to the metadata change content, and metadata quality documents are further generated, so that the auditing efficiency of technicians is improved. Specifically, by the method provided by the application, technicians can generate relevant process documents such as metadata change definition, a data quality list, a responsibility matrix and the like, and the process documents are mainly used for improving the standardization degree of the operation and maintenance process of the system, supervising the system change from each dimension, and defining the work such as data change content, influence range, responsibility person, data quality inspection and the like. In practical application, only the names of the first to fourth levels of functions corresponding to part of data in the document can be edited, so that other document contents required by process management can be efficiently and accurately completed. Meanwhile, the auditing efficiency of technicians can be improved, metadata is analyzed by identifying the type, coding and annotation information of the metadata indicated in the metadata quality document in a regular expression mode, various requirements in a data quality rule are identified, the metadata quality is automatically checked, and the data quality problem of the metadata is accurately identified.

The invention discloses a metadata quality determining method and device, which are used for determining corresponding metadata process documents according to the changing content of metadata, determining the changed metadata quality according to the metadata process documents, generating corresponding metadata quality documents, and performing metadata quality verification, so that the standardization level of metadata quality determination is improved, and the efficiency and accuracy of metadata quality determination are further improved.

according to the changes of metadata in the aspects of data format, data content, annotation and the like, corresponding metadata process documents can be determined, the changes of the metadata can be preset references, a reference library can be pre-established, and the metadata in the reference library is used as the references to determine the change content of the metadata. In some scenarios, technicians also need to supplement the multi-level function page names described by the newly added metadata, such as the one-level to four-level function names of the metadata in the smart grid scenario.

as previously described, the metadata reference library may be used to store metadata, or data indicated by metadata, as a reference for metadata changes.

By monitoring the differences in metadata relative to metadata stored in a metadata reference library, changes in metadata, such as changes in metadata format, attributes, or content, can be determined.

By establishing a metadata reference library for storing metadata, the metadata is used as a reference for metadata change comparison, the standardization level of metadata quality determination is improved, and the efficiency and accuracy of metadata quality determination are further improved.

S102, determining metadata quality according to the metadata process document, and generating a metadata quality document; the metadata quality document is used for indicating the metadata quality;

The metadata quality document is used to indicate the metadata quality, and specific content can be seen in the following embodiments.

At least one of a metadata change list, a metadata validation matrix, and a metadata quality list may be determined based on the change in metadata, thereby determining a process document corresponding to the changed metadata. Specifically, the determining the metadata process document according to the metadata change content includes:

It should be noted that only one or two of these three types of documents may be used, for example, the metadata responsibility matrix may be determined only from the user relationship of the metadata, and the other two types of documents need not be determined, and the final process document may only include the metadata responsibility matrix, which is the same for other types of documents.

The metadata change list is determined through the data format, the source and other attributes of the metadata, the metadata responsibility matrix is determined through the user management and the user authority relationship of the metadata, the metadata quality list is determined through the data content of the metadata, and then the metadata process document is determined through the metadata change list, the metadata responsibility matrix and the metadata quality list, so that the standardization level of metadata quality determination is improved, and the efficiency and the accuracy of metadata quality determination are further improved.
