[0052] The exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to help understanding, and should be considered as merely exemplary. Therefore, those skilled in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Also, for the sake of clarity and conciseness, the description below omits the description of well-known functions and structures.

[0053] It should be noted that the acquisition, storage, use, processing and the like of data in the technical solutions of the embodiments of the present application comply with relevant provisions of national laws and regulations.

[0054] Figure 1 is a schematic diagram of a flow of a page display method provided by an embodiment of the present application. As shown in the figure, the method comprises: Figure 1

[0055] Step 101: receiving a document browsing instruction, and determining a target document and a target page corresponding to the document browsing instruction.

[0056] The scheme of the embodiments of the present application is applied to a terminal. The document browsing instruction is used to open a target page of a target document. By using the document browsing instruction, a user can perform operations such as viewing and editing on the target page. If the target page is not specified by the document browsing instruction, a default page of the target document is determined as the target page.

[0057] Step 102: acquiring a basic relationship data model and document structured metadata corresponding to the target document.

[0058] The target document corresponds to a root node. The target document comprises a plurality of pages. Each page comprises one or more page nodes. One page node comprises one or more layer nodes. One layer node comprises one or more sub-layer nodes. The layer nodes and the sub-layer nodes are used to display page content such as text, pictures, tables and animations.

[0059] The basic relationship data model is used to provide hierarchical data of the target document. The hierarchical data can comprise: a root node and a corresponding page list thereof, a page and a corresponding page node list thereof, a page node and a page to which the page node belongs, a page node and a corresponding layer node list thereof, a layer node and a page node to which the layer node belongs, a layer node and a corresponding sub-layer node list thereof, and a sub-layer node and a layer node to which the sub-layer node belongs.

[0060] The document structured metadata is used to save metadata of the layer nodes. The metadata of the layer nodes comprises: a mapping relationship between a layer and a layer attribute, and the like. By analyzing the metadata of the layer nodes, layer data of the layer nodes can be generated. The layer data comprises: attribute values of various layer attributes.

[0061] Before acquiring the basic relationship data model and the document structured metadata corresponding to the target document, the following step is further included: acquiring binary data and document basic relationship data of the target document from a server. The binary data is original data of the target document. The basic relationship data comprises: a mapping list of a layer and a page node to which the layer belongs, hierarchical information of a document node, hierarchical information of a page node, and the like. By analyzing the binary data, the document structured metadata can be generated. Based on the document basic relationship data, the basic relationship data model is created.​

[0062] Step 103: Obtain at least one page node corresponding to the target page and at least one layer node corresponding to each page node from the basic relationship data model.

[0063] Step 104: Parse layer data of each layer node from the document structured metadata, and create a layer instance of the layer node according to the layer data of the layer node.

[0064] The layer instance is an object constructed by the runtime system for the layer. The layer instance is used to save data and states of the layer runtime, etc. The system realizes various functions such as layer display through the instance object.

[0065] Step 105: Display the target page in the target document according to the layer instance of each layer node.

[0066] After creating all the layer instances of the target page, the system calls the rendering engine to traverse all the layer instances of the target page through the rendering engine, and completes the content rendering and display of the target page.

[0067] In the scheme of the embodiment of the application, after receiving the document browsing instruction, the basic relationship data model and the document structured metadata corresponding to the target document are obtained. Each layer node corresponding to the target page is obtained from the basic relationship data model. The layer data of the layer node is parsed from the document structured metadata, and the layer instance of the layer node is created. Finally, the target page in the target document is displayed according to the layer instance of each layer node. Only the layers in the target page to be browsed are loaded, and the layer instances of the layers in the target page are generated. Compared with the method of generating the layer instances of all the layers, the system resources occupied can be reduced, and the smoothness of user operation can be improved.

[0068] Figure 2 is a schematic diagram of a flow of a page display method provided by another embodiment of the application. As shown in Figure 2 , the method comprises:

[0069] Step 201: Receive a document browsing instruction, and determine a target document and a target page corresponding to the document browsing instruction.

[0070] Step 202: Obtain a basic relationship data model and document structured metadata corresponding to the target document.

[0071] Step 203: Obtain at least one page node corresponding to the target page and at least one layer node corresponding to each page node from the basic relationship data model.

[0072] Step 204: Determine whether the metadata of each layer node is stored in the document structured metadata.

[0073] For each layer node, depending on whether the layer node's metadata is stored in the document's structured metadata, proceed to either step 205 or step 207. Specifically, if the layer node's metadata is not stored in the document's structured metadata, proceed to step 205. If the layer node's metadata is stored in the document's structured metadata, proceed to step 207.

[0074] Step 205: Obtain server-side data of layer nodes from the server; parse the server-side data to generate metadata of layer nodes.

[0075] Step 206: Store the metadata of the layer nodes in the document structured metadata.

[0076] Step 207: Obtain the metadata of the layer nodes from the document's structured metadata; parse the metadata of the layer nodes to generate the layer data of the layer nodes.

[0077] Step 208: Display the target page in the target document based on the layer instances of each layer node.

[0078] In the solution of this embodiment of the invention, it is not necessary to store the metadata of all layer nodes in the document structured metadata. Only the metadata of layer nodes with high loading frequency or those predicted to be needed for subsequent user operations can be pre-stored in the document structured metadata. If the metadata of a layer node that needs to be loaded is not stored in the document structured metadata, a metadata proxy is used to obtain the server-side data of that layer node from the server, enabling on-demand loading of layer nodes and further reducing the memory resources required for browsing or editing the document.

[0079] In one embodiment of the present invention, after displaying the target page in the target document based on the layer instances of each layer node, the method further includes: in response to the current system meeting the page recycling condition, obtaining multiple loaded pages and determining the dormancy duration of each loaded page; determining the recycled page from the multiple loaded pages based on the dormancy duration of each loaded page; determining at least one recycled page node corresponding to the recycled page and the recycled layer node corresponding to each recycled page node; deleting the layer instance of the recycled layer node from the node instance manager; and deleting the metadata of the recycled layer node from the document structured metadata.

[0080] Page recycling conditions can be set according to business needs, such as the system's current time reaching a preset time point or the system's resource utilization exceeding a preset utilization rate. The dormancy period is the time interval between the most recent load time of a loaded page and the current time. If the dormancy period of a loaded page exceeds a threshold, the loaded page is identified as a recycled page. The layer instance and metadata of the recycled layer node in the recycled page are deleted to avoid continuous runtime memory growth.

[0081] Figure 3 This is a schematic diagram illustrating the flow of a method for processing an instance retrieval request according to an embodiment of the present invention. Figure 3 As shown, the method includes:

[0082] Step 301: Receive instance retrieval request; determine the target layer node corresponding to the instance retrieval request.

[0083] Step 302: Determine whether the target layer node has been loaded.

[0084] If the target layer node is not loaded, proceed to step 303. If the target layer node has been loaded, proceed to step 307.

[0085] Step 303: Determine the editing scenario of the target document.

[0086] If the target document is edited collaboratively, multiple collaborators will edit it, triggering step 304. The server will send the document change information from other collaborators to the terminal. Based on this information, the terminal updates its local underlying relational data model and document structured metadata. The local calling modules on the terminal may be built upon the existing underlying relational data model. Therefore, relational validation of the calling modules is necessary to reduce issues such as displaying outdated page content and to prevent users from editing expired page content.

[0087] If the target document is edited in a single-user environment, then only one user is editing the target document, and step 306 is executed.

[0088] Step 304: Determine the dependency data of the target layer nodes from the basic relational data model; obtain the calling module corresponding to the instance acquisition request.

[0089] Dependency data includes: the parent page nodes of the target layer node, the parent pages of the parent page nodes, and the parent documents of the parent pages. The calling module obtains the node instance of the target layer node by sending an instance retrieval request.

[0090] Step 305: Use dependency data to verify the relationships between calling modules.

[0091] The calling module is the module that calls the node instance of the target layer node. The calling module's calling information is obtained. This information includes: the calling page node, the calling page, and the calling document. Dependency data is used to perform relationship checks on the calling module, including: determining whether the calling page node matches its parent page node, whether the calling page matches its parent page, and whether the calling document matches its parent document.

[0092] If the calling module passes the dependency data relationship validation, proceed to step 306. If the calling module fails the dependency data relationship validation, generate a prompt message to guide the user in troubleshooting.

[0093] Step 306: Parse the layer data of the target layer node from the document structured metadata; create a layer instance of the target layer node based on the layer data of the target layer node.

[0094] Step 307: Obtain the layer instance of the target layer node from the node instance manager.

[0095] If the target layer node has already been loaded, the interval between the most recent loading time of the target layer node and the current time is very short. There is no need to perform relationship verification on the calling module. The layer instance of the target layer node can be obtained directly from the node instance manager to improve system processing efficiency.

[0096] Step 308: Display the layer or page based on the layer instance of the target layer node.

[0097] In the solution of this embodiment of the invention, after receiving an instance retrieval request, if the editing scenario of the target document is collaborative, the relationship verification of the calling module of the instance retrieval request needs to be performed to reduce situations such as the terminal displaying an expired page and improve the reliability of multi-party collaboration. If the editing scenario of the target document is single-machine, there is no need to perform relationship verification on the calling module; the layer data of the target layer node is directly parsed, and the layer or page is displayed.

[0098] In one embodiment of the present invention, the editing scenario of the target document is collaborative; after receiving the document browsing instruction, the method further includes: receiving document change information for the target document sent by the server; wherein the document change information is generated based on the editing submission information of other collaborators to the target document; and updating the basic relationship data model and / or document structured metadata based on the document change information.

[0099] Figure 4 This is a schematic diagram illustrating the flow of a multi-party document editing method according to an embodiment of the present invention. Figure 4 As shown, the method includes:

[0100] Step 401: Other collaborating terminals send edit submission information for the target document to the service.

[0101] Step 402: The server generates document change information for the target document based on the edit submission information.

[0102] The server can preset a period and execute steps 402 to 404, that is, send the document change information generated within the period to each collaborator at a preset frequency.

[0103] Step 403: The server determines the collaborators corresponding to the target document.

[0104] Step 404: The server sends the document change information to the collaborating party's terminal.

[0105] Step 405: The collaborating terminal updates its local basic relational data model and / or document structured metadata based on the document change information.

[0106] Before the collaborating party terminal updates its local basic relationship data model and / or document structured metadata based on document change information, the process also includes: displaying relevant information about the document change; and, in response to receiving a confirmation instruction for the relevant information, executing the steps of updating the local basic relationship data model and / or document structured metadata based on the document change information. This relevant information includes: changed page, changed layer, changed content, submission time, and submitting collaborator.

[0107] Based on document change information, update the local basic relationship data model and document structured metadata to ensure that the page content displayed on the collaborating party's terminal is consistent with the edit page content submitted by other collaborating party terminals.

[0108] Step 406: The collaborating terminal performs page display and editing processes based on the local basic relationship data model and document structured metadata.

[0109] For example, collaborator 1 and collaborator 2 jointly edit a target document. Collaborator 1 generates a new page node 1 in the target document and configures the layer nodes under page node 1. Collaborator 1's terminal uploads the configuration information of page node 1 as document change information to the server. The server generates document change information based on the configuration information of page node 1 and sends it to collaborator 2's terminal. Collaborator 2's terminal automatically updates its local basic relational data model based on the document change information to add the configuration information of page node 1 to its local basic relational data model.

[0110] The solution of this invention can be applied to both collaborating party terminals and other collaborating party terminals. By using the solution of this invention, when multiple collaborating parties are jointly editing a document, each collaborating party can promptly obtain the edited content from other collaborating parties, improving document editing efficiency and reducing unnecessary operations.

[0150] Receive a document browsing instruction and determine the target document and target page corresponding to the document browsing instruction;

[0151] Obtain the basic relational data model and document structure metadata corresponding to the target document;

[0152] From the basic relational data model, obtain at least one page node corresponding to the target page and at least one layer node corresponding to each page node;

[0153] For each layer node, the layer data of the layer node is parsed from the document's structured metadata; and a layer instance of the layer node is created based on the layer data of the layer node.

[0154] Based on the layer instances of each layer node, display the target page in the target document.

[0155] According to the technical solution of this invention, after receiving a document browsing instruction, the basic relational data model and document structured metadata corresponding to the target document are obtained. From the basic relational data model, the layer nodes corresponding to the target page are obtained. Then, from the document structured metadata, the layer data of the layer nodes is parsed, and layer instances of the layer nodes are created. Finally, based on the layer instances of each layer node, the target page in the target document is displayed. Only the layers in the browsed target page need to be loaded, and layer instances of the layers in the target page are generated. Compared to generating layer instances of all layers, this reduces the system resources consumed and improves the smoothness of user operation.

[0156] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
