Abstract
The invention provides a method for managing metadata, which is used for solving the technical problem that the existing metadata management method can only carry out operation management on the metadata of main data but cannot carry out operation management on the metadata of the metadata.
Description
Technical Field
The invention relates to the technical field of data management, in particular to a method for managing metadata.
Background
With the rapid proliferation of smart computing devices and the internet, the volume of data has presented a explosive growth. The strategic value of data, as a new production data, has been regarded by the academic and industrial circles. Metadata, as data of data, can describe the data themselves in detail, improve the quality of the data, and play a crucial role in playing the value of the data.
In the prior art, the value of metadata as such is not fully recognized, merely as an aid to the main data. This results in that the existing metadata management methods can only operate and manage the metadata of the main data, and do not consider how to operate and manage the metadata of the metadata. However, the explosion of the main data inevitably brings a huge increase of the metadata, and the value of the metadata is not even inferior to that of the main data, and at this time, the metadata cannot be treated as the metadata.
In view of the above problems, it is necessary to design a new method for managing metadata to fully utilize the value of the metadata itself.
Disclosure of Invention
The invention provides a method for managing metadata, which is used for solving the technical problem that the existing metadata management can only carry out operation management on the metadata of main data but cannot carry out operation management on the metadata of the metadata.
In order to achieve the purpose of the invention, the invention provides the following technical scheme: a method of managing metadata, comprising:
creating one or more metadata models and their properties in a configuration file;
configuring metadata models of different types of data in a configuration file, and under the default condition, not limiting the determinable metadata models of the data;
the hierarchy of metadata is configured in the configuration file, limited by default to 3 levels, i.e.: metadata for the main data, metadata defined as metadata for the binary data, and metadata for the main data, may be determined, and so on.
Selecting main data of metadata to be determined and metadata of the metadata to be determined on a user interface;
preferably, the selecting means specifically includes: if receiving a click operation aiming at the main data display area of the metadata to be determined, popping up a metadata determination dialog box of the main data;
displaying one or more metadata models created in a configuration file and characteristics thereof in a main data metadata determination dialog;
selecting a metadata model to be determined in a metadata determination dialog box of the main data, and inputting a characteristic value of the metadata model;
if double-click operation aiming at the main data display area is received, popping up the metadata display area of the main data;
if receiving a click operation aiming at the metadata display area, popping up a metadata determination dialog box of the metadata;
selecting a metadata model to be determined in a metadata determination dialog box of metadata, and inputting a characteristic value of the metadata model;
if the scanning operation aiming at the data display area is received, all the data with the determined metadata and the metadata thereof are displayed on the current user interface, and the user can directly modify the metadata, wherein the data comprises the main data and the metadata.
And presetting a metadata generation button, clicking the metadata generation button, and generating a Json file of the hierarchical structure metadata. The structure of the Json file is as follows:
further, the configuration file can be stored in a server or a local place, and the user calls the configuration file through the URL.
On the other hand, the management of metadata needs to depend on a configuration unit and a multi-layer metadata determination unit, specifically:
the configuration unit specifically comprises:
creating one or more metadata models and their properties in a configuration file;
configuring metadata models of different types of data in a configuration file, and under the default condition, not limiting the determinable metadata models of the data;
the hierarchy of metadata is configured in the configuration file, limited by default to 3 levels, i.e.: metadata for the main data, metadata defined as metadata for the binary data, and metadata for the main data, may be determined, and so on.
The multi-layer metadata determination unit specifically includes:
selecting main data of metadata to be determined and metadata of the metadata to be determined on a user interface;
preferably, the selecting means specifically includes: if receiving a click operation aiming at the main data display area of the metadata to be determined, popping up a metadata determination dialog box of the main data;
displaying one or more metadata models created in a configuration file and characteristics thereof in a main data metadata determination dialog;
selecting a metadata model to be determined in a metadata determination dialog box of the main data, and inputting a characteristic value of the metadata model;
if double-click operation aiming at the main data display area is received, popping up the metadata display area of the main data;
if receiving a click operation aiming at the metadata display area, popping up a metadata determination dialog box of the metadata;
selecting a metadata model to be determined in a metadata determination dialog box of metadata, and inputting a characteristic value of the metadata model;
if the scanning operation aiming at the data display area is received, all the data with the determined metadata and the metadata thereof are displayed on the current user interface, and the user can directly modify the metadata, wherein the data comprises the main data and the metadata.
Presetting a metadata generation button, clicking the metadata generation button, and generating a Json file of the hierarchical structure metadata;
drawings
In order to more clearly describe the technical solution of the present invention, the drawings in the embodiments are briefly described below.
FIG. 1 is a schematic of the present invention;
FIG. 2 is a schematic view of a configuration file;
Detailed Description
An embodiment of the present application provides a method for managing metadata, including:
as shown in fig. 2, 2 metadata models, which are "author" and "Age" corresponding to the metaModel, respectively, are created in the configuration file; that is, only the 2 metamodels can be determined as the main data or the metadata of the metadata;
as shown in fig. 1, it is determined that the main data of the metadata to be determined is a picture data, and if the picture is clicked, a metadata determination dialog box, i.e., "author": the circular area of Mike is shown as,
determine its metadata as "author": mike, "Author" is an option configured in the configuration document MetaModel;
as shown in fig. 1, if the metadata has been determined and is not displayed in the user interface, double clicking on the main data area pops up the metadata display area, i.e., "author" in the figure: a circular area as shown by Mike;
clicking the metadata area, popping up a binary data determination area, namely' age: 25 "in which metadata of the metadata, i.e., the binary data, can be determined, which in this example is determined as" age: 25 ";
since only the metadata model of the author is specified as age in the configuration file "metamodel Limit" option, only the age can be used to add metadata to the metadata author, forming the binary data "age": 25;
as shown in fig. 2, "Level": 2 limits the level of metadata to 2, corresponding to the metadata in fig. 1 being at most only binary data;
while the invention has been described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
