Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 6 .

FIG. 1 is a schematic structural diagram of a knowledge distribution system 100 provided by an embodiment of the present invention. As shown in Figure 1, the knowledge publishing system 100 includes:

- A knowledge distribution center 10 configured to distribute knowledge in an organization. The organization may be an enterprise, or a group or park including multiple enterprises, or a unit within an enterprise, etc. Different enterprises or units within the organization may access some or all of the information managed by the knowledge distribution center 10 Knowledge. Knowledge can be defined by a semantic model, and the semantic model can be described by an ontology description language such as RDF or OWL, or described by a knowledge graph.

- At least one data integration system 20, each data integration system 20 configured to perform data integration of devices or systems in the connected organization. As shown in FIG. 1 , the data integration system 20 can be deployed on the cloud 500 or on the edge side 600 . A data integration system 20 may connect one or more devices or systems in the organization. The data integration system 20 may be a data center, a data platform, or other systems for integrating data. The data integration system 20 deployed on the cloud can interact with multiple applications 70 deployed on the cloud, and further send the knowledge acquired from the knowledge distribution center 10 to each application 70 . Each application 70 executes its business logic 701 based on the received knowledge (here, knowledge transformed into data 702).

- at least one sidecar system 30, wherein one sidecar system 30 is connected to one data integration system 20, each sidecar system 30 is configured to: register the connected data integration system 20 at the knowledge distribution center 10, and The connected data integration system 20 acquires the knowledge distributed by the knowledge distribution center 10 .

Wherein, the knowledge distribution center 10 is located in the control plane 300 of the service grid, and at least one data integration system 20 and the sidecar system 30 connected to each data integration system 20 are located in the data plane 400 of the service grid.

Typically, an organization defines and stores a complete business domain knowledge model in the cloud. For the data integration system on the edge side, a semantic model that satisfies on-site data integration can be defined to describe knowledge. The semantic model is a small part of the whole knowledge model. In addition, the data integration system in the cloud can use partial knowledge of the business domain or a complete semantic model to perform data integration and fusion of heterogeneous vertical systems with multiple different data sources. In the embodiment of the present invention, combined with the service grid technology, each data integration system 20 can be registered and discovered at the knowledge distribution center 10 , and then knowledge can be distributed to each data integration system 20 through the sidecar system 30 .

In the knowledge publishing system 100 shown in FIG. 1 , in the control plane 300 , the knowledge distribution center 10 can store and manage all the knowledge in an organization and define the knowledge. A non-intrusive sidecar system 30 is added to each data integration system 20 by using service grid technology. Through the sidecar system 30 , in the data plane 400 , the data integration systems 20 of the cloud 500 and the edge side 600 can be registered with the knowledge distribution center 10 , and each data integration system 20 can be discovered by the knowledge distribution center 10 . The knowledge distribution center 10 distributes knowledge to the data integration system 20 by calling the application programming interface (Application Programming Interface, API) of the sidecar system 30.

Here, the service grid technology is used to configure sidecar systems 30 (sidecar) for each data integration system 20 located on the edge side 600 or cloud 500, and the knowledge distribution center 10 is placed on the control plane of the service grid, and the sidecar system The system 30 and its connected data integration system 20 are placed in the data plane 400 of the service grid, so that the sidecar system 30 can be used to realize data integration under the premise of minimizing changes to the data integration system 20 and the knowledge distribution center 10 The registration of the system 20 and the function of forwarding the knowledge distributed by the knowledge distribution center 10 to the data integration system 20 only need to realize the simple interaction between the data integration system 20 and the free ride system 30, as well as between the sidecar system 30 and the knowledge distribution center 10 , the distribution of knowledge to each data integration system 20 is realized.

Optionally, the sidecar system 30 can obtain the knowledge distributed by the knowledge distribution center 10 for the connected data integration system 20 in one of the following two ways.

Method 1. Subscribe

-The sidecar system 30 can be connected to the data integration system 20 and subscribe to the knowledge related to the data integration system 20 at the knowledge distribution center 10, then the knowledge distribution center 10 can publish the knowledge subscribed by the data integration system 20 when distributing the knowledge in the organization The knowledge related to the data integration system 20 , and the sidecar system 30 can forward the knowledge related to the data integration system 20 subscribed by the data integration system 20 published by the knowledge distribution center 10 to the data integration system 20 .

Method 2. Message Forwarding

The data integration system 20 can send a first request message to the connected sidecar system 30, and the first request message is used to request knowledge related to the data integration system 20 distributed to the knowledge distribution center 10; the sidecar system 30 sends the knowledge distribution center to the knowledge distribution center 10 forwards the first request message; in this way, when there is knowledge related to the data integration system 20 to be distributed by the knowledge distribution center 10, it can respond to the first request message and send the distributed information related to the data integration system 20 to the sidecar system 30. , and the sidecar system 30 forwards the knowledge related to the data integration system 20 distributed by the knowledge distribution center 10 to the data integration system 20 .

Optionally, the knowledge distribution center 10 may provide an interface for building and updating knowledge. An interface may include a user interface or a device interface. Among them, the user interface is used for users to create or update knowledge, and the device interface is used to obtain knowledge from other devices. The acquired knowledge can be managed uniformly by the knowledge distribution center 10 and further distributed to each data integration system 20 .

The knowledge distribution center 10 can receive knowledge updates from users in a variety of ways including the following two ways:

Method 1: The user specifies which data integration system or systems 20 the updated knowledge is related to

Mode 2: The data integration system 20 notifies the knowledge distribution center 10 which part of the knowledge it is related to when registering. The data integration system 20 distributes knowledge.

Specifically, for the first method, after receiving the user's knowledge update request message (referred to as "the second request message"), the knowledge distribution center 10 updates the knowledge in the organization according to the second request message. The user can indicate the data integration system 20 related to the updated knowledge through the first indication information in the second request message, and the knowledge distribution center 10 can distribute the updated knowledge to the data integration system 20 indicated by the first indication information.

For mode 2, when the data integration system 20 registers at the knowledge distribution center 10 through the connected sidecar system 30 after startup, it can send a third request message, and the third request message can include the second indication information for Indicates that the data integration system 20 is associated with the first portion of knowledge in the organization. And the sidecar system 30 forwards the third request message to the knowledge distribution center 10 when registering the connected data integration system 20 at the knowledge distribution center 10 . After receiving the third request message, the knowledge distribution center 10 determines that the data integration system 20 is related to the first part of the knowledge in the organization according to the second indication information, and after receiving the user's request to update the knowledge (herein marked as "fourth part") request message"), update the knowledge in the organization according to the fourth request message, and determine the data integration system 20 related to the updated knowledge according to the second indication information in the third request message when each data integration system 20 is registered, and send The data integration system 20 determined to be relevant to the updated knowledge distributes the updated knowledge.

In the first manner above, the user defines which part of knowledge the data integration system 20 is related to through the user interface. The user interface may be in the form of a graphical user interface (Graphic User Interface, GUI) or in the form of a configuration file.

In addition, the knowledge distributed by the knowledge distribution center 10 is defined by multiple semantic models of different versions, and the user can select a specific version of the semantic model. Specifically, the knowledge distribution center 10 receives a request message for the user to select a semantic model version, and uses the semantic model of the version specified in the request message to define knowledge in the organization. Optionally, the knowledge distribution center 10 can also notify the data integration system 20 of the version of the semantic model used by the knowledge in the organization by sending a message to each sidecar system 30 . Of course, the user may not specify a version, and the knowledge distribution center 10 uses the semantic model of the default version to define knowledge. The knowledge distribution center 10 can use the same version of the semantic model for all the knowledge it distributes, or use one version of the semantic model for some knowledge, and use another version of the semantic model for other parts of knowledge. Here, flexible settings can be made according to the requirements of different data integration systems 20 .

Further optionally, the knowledge distribution center 10 can be further divided into: a knowledge management module 111 , a registration center 112 and a configuration center 113 . Among them, the knowledge management module 111 can use the semantic model to manage the knowledge in the whole organization. In addition, the version management system can also be connected to manage the semantic models of multiple versions. The registration center 112 communicates with the sidecar system 30 to realize the registration of each data integration system 20, so that these data integration systems 20 can be discovered, so that the knowledge distribution center 10 of the control plane can discover these data integration systems 20 and route knowledge to The right data integration system20. The user can configure a specific semantic model through the configuration center 113, and can choose different versions of the semantic model. Afterwards, the knowledge defined by the semantic model is distributed to the data integration system 20 by calling the API of the sidecar system 30 .

In the data plane 400, the non-intrusive sidecar system 30 provides the function of service registration in the control plane 300, and provides the functions of routing forwarding and flow control as a proxy. The sidecar system 30 has nothing to do with the logic of the knowledge distribution process in the embodiment of the present invention, and is decoupled from the realization of the data integration system 20 . The sidecar system 30 can be independent of the data integration system 20 or integrated in the data integration system 20 . An exemplary structure of the data integration system 20 with the sidecar system 30 can be shown in FIG. 7 . Among them, the sidecar system 30 can realize the registration function 311a, the discovery function 311b, the routing and forwarding and flow control 312a, and the configuration client 312b, etc.

FIG. 2 shows the flow of the knowledge distribution method 200 provided by the embodiment of the present invention. The method 200 can be executed by the knowledge distribution center 10 , the sidecar system 30 and the data integration system 20 in the knowledge distribution system 100 shown in FIG. 1 . Specifically, the method 200 may include the following steps:

S201: Each data integration system 20 registers at the knowledge distribution center 10 through the sidecar system 30 connected to itself.

Optionally, the data integration system 20 can be registered at the knowledge distribution center 10 through the sidecar system 30 when starting up.

S202: The knowledge distribution center 10 accepts the registration of each data integration system 20 .

Here, the knowledge distribution center 10 can authenticate each data integration system 20, determine whether to allow the registration of the data integration system 20, and if allowed, record the identification of the data integration system 20 (such as the unified management and distribution for each data integration system 20 ID, the name of the data integration system 20, etc.) and address information (such as IP address); if not allowed, a rejection message can be returned to the data integration system 20 through the sidecar system 30, and the reason for the rejection of registration can be carried in the message.

S203: Each sidecar system 30 obtains the knowledge distributed by the knowledge distribution center 10 for the data integration system 20 connected to itself. As mentioned above, when the sidecar system 30 acquires knowledge for the data integration system 20, there are two methods: method 1, subscription and method 2, message forwarding.

If method 1 is adopted, step S203 may include the following sub-steps:

- S2031: The sidecar system 30 subscribes the knowledge related to the data integration system 20 at the knowledge distribution center 10 for the connected data integration system 20;

- S2032: The sidecar system 30 forwards the knowledge related to the data integration system 20 subscribed by the data integration system 20 published by the knowledge distribution center 10 to the connected data integration system 20 .

In step S209 , when the knowledge distribution center 10 distributes S209 knowledge to the registered data integration system 20 through the sidecar system 30 , it can publish the knowledge related to the data integration system 20 subscribed by the data integration system 20 .

If mode 2 is adopted, step S203 may include the following sub-steps:

- S2033: The sidecar system 30 forwards the first request message from the connected data integration system 20 to the knowledge distribution center 10, the first request message is used to request the knowledge distribution center 10 for knowledge related to the data integration system 20 to be distributed;

- S2034: The sidecar system 30 forwards to the data integration system 20 the knowledge related to the data integration system 20 distributed by the knowledge distribution center 10 in response to the first request message.

In step S209, when the knowledge distribution center 10 distributes S209 knowledge to the registered data integration system 20 through the sidecar system 30, the knowledge distribution center 10 may distribute the knowledge related to the data integration system 20 in response to the above-mentioned first request message.

Optionally, the knowledge distribution center 10 may also receive updates of knowledge from users. As mentioned above, there are also two optional ways to implement: the first way, the user specifies which data integration system or systems 20 the updated knowledge is related to; Part of the knowledge is related, and the knowledge distribution center 10 distributes the knowledge to the data integration system 20 when the knowledge distribution center 10 determines that the updated knowledge is related to the part registered in the data integration system 20 when the user updates the knowledge.

If mode 1 is adopted, correspondingly, the method 200 may further include the following steps:

- S204: The knowledge distribution center 10 receives a second request message for the user to update the knowledge, wherein the second request message includes first indication information, and the first indication information is used to indicate the data integration system 20 related to the updated knowledge;

- S205: The knowledge distribution center 10 updates the knowledge in the organization according to the second request message.

In step S209, when distributing knowledge to the data integration system 20, the knowledge distribution center 10 may distribute updated knowledge to the data integration system 20 indicated by the first indication information.

If the second method is adopted, correspondingly, in step S201, when each data integration system 20 registers at the knowledge distribution center 10 through the sidecar system 30 connected to itself, the data integration system 20 can pass the sidecar system 30 when it starts itself. 30. Send the third request message registered at the knowledge distribution center 10 to the knowledge distribution center 10, the third request message includes second indication information, and the second indication information is used to indicate that the data integration system 20 is related to the first part of knowledge in the organization , and the sidecar system 30 forwards the third request message to the knowledge distribution center 10. When the knowledge distribution center 10 accepts the registration of each data integration system 20 in step S202, the knowledge distribution center 10 receives the third request message, and determines the relationship between the data integration system 20 and the knowledge in the organization according to the second indication information in the third request message. related to the first part of .

Correspondingly, method 200 may also include the following steps:

- S206: the knowledge distribution center 10 receives the fourth request message for the user to update the knowledge;

- S207: The knowledge distribution center 10 updates the knowledge in the organization according to the fourth request message;

- S208: The knowledge distribution center 10 determines the data integration system 20 related to the updated knowledge according to the second indication information in the third request message when each data integration system 20 is registered;

In step S209, when the knowledge distribution center 10 distributes knowledge to registered data integration systems 20 through the sidecar system 30, the updated knowledge may be distributed to the determined data integration systems 20 related to the updated knowledge.

Next, the knowledge distribution center 10 provided by the embodiment of the present invention will be described with reference to FIG. 3 , the data integration system 20 provided by the embodiment of the present invention will be described with reference to FIG. 4 , and the sidecar system 30 provided by the embodiment of the present invention will be described with reference to FIG. 5 .
