It should be understood that the number of editing terminals, networks, servers, and follower terminals in fig. 1 is merely illustrative. There may be any number of editing terminals, networks, servers, and follower terminals, as desired for implementation.

With continued reference to FIG. 2, a timing diagram for one embodiment of a graphic modification system according to the present disclosure is shown.

The graphic modification system of the present embodiment includes: an editing terminal and a following terminal. The editing terminal is used for responding to an editing instruction of a graph in the collaborative document, acquiring data in a first data format corresponding to the graph, converting the data in the first data format into data in a second data format, generating a change instruction of the graph in the collaborative document based on the data in the second data format, and sending the change instruction to the following terminal through the target server; and the following terminal is used for responding to the received change instruction, changing the data in the second data format corresponding to the current graph in the collaborative document by using the change information included in the change instruction to obtain the changed data in the second data format, converting the changed data in the second data format into the data in the first data format, and changing the graph in the collaborative document by using the data in the first data format.

As shown in fig. 2, in step 201, in response to detecting an editing instruction for a graphic in a collaborative document, an editing terminal acquires data in a first data format corresponding to the graphic.

In the present embodiment, the editing terminal may determine whether an editing instruction by the user for the graphics in the collaborative document is detected. The collaborative document may also be referred to as a shared document or an online document, and generally refers to a document tool used online in a browser (not local to a computer), and is characterized in that the written content of the document is automatically saved in real time, and multi-person collaborative editing is supported, that is, multiple persons are supported to edit the same document at the same time. The graphics may include, but are not limited to: a flow chart and a UML (UML-Unified Model Language) diagram.

For example, if the graph is a flowchart, the user may perform the following editing operation on the flowchart in the collaborative document: adding a graphical block in the flowchart in the collaborative document, deleting a graphical block in the flowchart in the collaborative document, and changing a graphical block in the flowchart in the collaborative document.

Here, a built-in "graphic editor" may exist in the collaborative document, a user may edit Graphics in the collaborative document as needed by using the "graphic editor", and the Graphics may exist in the document in the form of SVG (Scalable Vector Graphics) pictures after the editing is completed, so as to facilitate a reader of the document to read the Graphics.

If an editing instruction for the graph in the collaborative document is detected, the editing terminal can acquire data in a first data format corresponding to the graph. Here, the data corresponding to the graphic may be data corresponding to a graphic change portion. The first data format may be a data format for drawing graphics.

As an example, grapheiditor can be employed as the above-described graphic editor. The graphpaditor is an open source graphical editor. When the grapheiditor is used as a graphic editor in a collaborative document, the first data format is usually an XML format. If the graph editor is used, getgraph XML provided by the graph editor can be called to obtain XML-formatted data corresponding to the edited graph.

In step 202, the editing terminal converts data in the first data format into data in the second data format.

In this embodiment, the editing terminal may analyze the data in the first data format to convert the data in the first data format into data in the second data format. The second data format may be a data format for collaborative data.

As an example, collaborative editing for graphics may be implemented using a collaborative editing algorithm on the basis of graphpaditor. The collaborative editing algorithm can automatically resolve conflicts when multiple people edit the flow chart. When a collaborative editing algorithm is adopted for data collaboration, the second data format may be a JSON format.

Here, the editing terminal may convert the XML-formatted data corresponding to the graphic change portion into JSON-formatted data. The editing terminal may analyze a structure of the XML-formatted data, for example, the XML-formatted data may be composed of a top mxgraphModel tag and a plurality of mxCell, an additional child element may be provided under the mxCell, and the editing terminal may fill a content in the top mxgraphModel tag, a content in the plurality of mxCell, and a child element under the mxCell in the XML-formatted data to corresponding positions in the JSON-formatted template according to a preset positional relationship, so as to obtain the JSON-formatted data corresponding to the graphic modification part.

In step 203, the editing terminal generates a change instruction for the graphics in the collaborative document based on the data in the second data format.

In this embodiment, the editing terminal may generate a change instruction for the graphics in the collaborative document based on the data in the second data format. The modification instruction may include modification information of graphics in the collaborative document. The data in the second data format may include change information of the graphics in the collaborative document, and the change information may include a change type of the graphics, such as addition, deletion, or modification. The editing terminal may generate a modification instruction corresponding to the modification type. The change instruction is generally used to instruct a change operation to be performed with respect to the graphics in the collaborative document.

In step 204, the editing terminal sends a change instruction to the target server.

In this embodiment, the editing terminal may send the change instruction to the target server. The target server may be a server that provides support for the various functions of the collaborative document described above. The target server can receive the change instruction sent by the editing terminal and send the received change instruction to the following terminal accessing the collaborative document.

In step 205, the target server sends a change instruction to the follower terminal.

In this embodiment, the target server may send a change instruction to the follower terminal. Here, if the editing terminal accessing the collaborative document performs an editing operation on the graphic in the collaborative document, the editing terminal may send a change instruction to the follower terminal by using the target server.

In step 206, in response to receiving the change instruction, the following terminal changes the data in the second data format corresponding to the current graph in the collaborative document by using the change information included in the change instruction, so as to obtain the changed data in the second data format.

In this embodiment, the follower terminal may determine whether a change instruction for changing the graphics in the collaborative document is received. If the change instruction is received, the following terminal can change the data in the second data format corresponding to the current graph in the collaborative document by using the change information included in the change instruction to obtain the changed data in the second data format.

In step 207, the follower terminal converts the modified data in the second data format into data in the first data format.

In this embodiment, the follower terminal may convert the modified data in the second data format into data in the first data format. As an example, the follower terminal may convert the above-described modified JSON-formatted data into XML-formatted data. The follower terminal may analyze the modified JSON formatted data. For example, the following terminal may fill each content in the data in the JSON format into a corresponding position in the template in the XML format according to a preset positional relationship, so as to obtain the data in the corresponding XML format.

In step 208, the follower terminal modifies the graph in the collaborative document using the data in the first data format.

In this embodiment, the following terminal may change the graph in the collaborative document by using the converted data in the first data format. As an example, if the graphpaditor is used as the graphic editor, setgraphpaxml provided by the graphpaditor may be called to present a graphic indicated by the data in the first data format in a current graphic, so as to modify the graphic in the collaborative document.

The system provided by the above embodiment of the present disclosure realizes collaborative editing for a graphic in a collaborative document, and when a user edits a graphic (for example, a flowchart) in the collaborative document by using an editing terminal, a change process of the graphic can be presented on a following terminal accessing the collaborative document.

In some alternative implementations, the change instruction may be sent by the target server to the follower terminal by using a collaborative editing algorithm. If a plurality of persons edit the same flow chart in the collaborative document at the same time, the target server can solve the conflict by utilizing a collaborative editing algorithm, and the conflict can be solved without lock or user intervention by using the collaborative editing algorithm. The target server can solve the conflict generated by the fact that a plurality of editing terminals send the change instruction at the same time by using a collaborative editing algorithm through the following steps: the method comprises the steps of responding to the received change instructions sent by at least two user terminals, and obtaining the receiving time of the at least two change instructions, wherein the user terminals comprise the editing terminal; determining whether to modify the modification instruction based on the receiving time of the at least two modification instructions; and if so, correcting the change instruction, and sending the corrected change instruction to the following terminal. The target server may further determine whether to modify the modification instruction based on the reception times of the at least two modification instructions by: determining whether the receiving time corresponding to the change instruction sent by the editing terminal is earlier than the receiving time corresponding to the change instruction sent by other user terminals; if not, the modification instruction is modified.

As an example, if a process graph block exists in a current collaborative document, a user a and a user B edit a graph in the collaborative document at the same time, and if the target server first receives a change instruction sent by a user terminal a used by the user a: adding a decision graph block behind a first graph block in the collaborative document, and then receiving a change instruction sent by a user terminal B used by the user B: adding a data graphic block after the first graphic block in the collaborative document. If the editing terminal is the user terminal B, since the receiving time corresponding to the modification instruction sent by the user terminal B is later than the receiving time corresponding to the modification instruction sent by the user terminal a, the target server generally needs to modify the modification instruction sent by the user terminal B into: a data graphical block is added after the second graphical block in the collaborative document. And then, the modified change instruction can be sent to the following terminal, so that the conflict problem is solved.

In some optional implementations, the editing terminal may generate a change instruction for the graph in the collaborative document based on the data in the second data format in the following manner: the editing terminal may compare the data in the second data format with the target data to obtain change information of the graph in the collaborative document, and generate a change instruction including the change information. The target data may be data in a second data format corresponding to a graphic obtained by the user editing a graphic in the collaborative document last time. The data received this time is compared with the data received last time to obtain the data of the changed part of the graph. As an example, the editing terminal may determine the difference between the Data received this time and the Data received last time by using the open source library "just-diff" and convert the difference into an op (operation) in a corresponding Data-SDK (Software Development Kit), which is a Data collaborative SDK based on a collaborative editing algorithm, and the op may enable the Data to be changed from one state to another state, for example, the op from 'abc' to 'abcd' is insert ('d',3), i.e., a character d is added after the third character.

In some optional implementations, the change information may include: the position, size and category of the added graphic block in the collaborative document; or an identifier of a deleted graphic block in the collaborative document; or an identifier of the modified graphical block and a size of the modified graphical block in the collaborative document. The size of the graphic block may include a width and a height of the graphic block. The categories of the graphic blocks may include, but are not limited to: a process graph block, a decision graph block, a document graph block and a data graph block. When a flowchart is inserted in a graphic editor, a corresponding identifier is typically generated for the inserted graphic block, and thus, the identifier of the graphic block may be used to indicate the graphic block in the flowchart.

With continued reference to FIG. 3, a flow 300 of one embodiment of a graph altering method according to the present disclosure is shown. The graph changing method is applied to an editing terminal and comprises the following steps:

step 301, in response to detecting an editing instruction for a graph in the collaborative document, acquiring data in a first data format corresponding to the graph.

In the present embodiment, an execution subject of the graphic change method (e.g., the editing terminal shown in fig. 1) may determine whether an editing instruction by a user for a graphic in a collaborative document is detected. The collaborative document may also be referred to as a shared document or an online document, and generally refers to a document tool used online in a browser, and is characterized in that the content written by the document is automatically saved in real time, and multi-person collaborative editing is supported, that is, multiple persons are supported to edit the same document at the same time. The graphics may include, but are not limited to: a flow chart and a UML diagram.

If an editing instruction for a graphic in the collaborative document is detected, the execution subject may obtain data in a first data format corresponding to the graphic. Here, the data corresponding to the graphic may be data corresponding to a graphic change portion. The first data format may be a data format for drawing graphics.

Step 302, converting the data in the first data format into the data in the second data format.

In this embodiment, the execution body may analyze the data in the first data format to convert the data in the first data format into the data in the second data format. The second data format may be a data format for collaborative data.

Here, the execution body may convert the XML-formatted data corresponding to the graphic change portion into JSON-formatted data. The execution body may analyze a structure of the XML-formatted data, for example, the XML-formatted data may be composed of a top mxgraphcel tag and a plurality of mxCell, where additional child elements are provided under the mxCell, and the execution body may respectively fill, according to a preset positional relationship, a content in the top mxgraphcel tag, a content in the plurality of mxCell, and a child element under the mxCell in the XML-formatted data to corresponding positions in a JSON-formatted template, so as to obtain JSON-formatted data corresponding to the pattern modification part.

Step 303, generating a change instruction for the graph in the collaborative document based on the data in the second data format.

In this embodiment, the execution subject may generate a change instruction for the graphics in the collaborative document based on the data in the second data format. The modification instruction may include modification information of graphics in the collaborative document. The data in the second data format may include change information of the graphics in the collaborative document, and the change information may include a change type of the graphics, such as addition, deletion, or modification. The execution subject may generate a modification instruction corresponding to the modification type. The change instruction is generally used to instruct a change operation to be performed with respect to the graphics in the collaborative document.

And step 304, sending a change instruction to the following terminal through the target server.

In this embodiment, the execution subject may send a change instruction to the following terminal by using the target server. The target server may be a server that provides support for various functions of the collaborative document. The target server may receive a change instruction sent by the execution subject, and send the received change instruction to a follower terminal accessing the collaborative document.

In this embodiment, after receiving a change instruction for a graphic in the collaborative document, the following terminal may change, by using change information included in the change instruction, data in a second data format corresponding to a current graphic in the collaborative document to obtain data in the second data format after the change. The modified data in the second data format may then be converted into data in the first data format. Finally, the graph in the collaborative document may be modified by using the converted data in the first data format.

The method provided by the above embodiment of the present disclosure realizes collaborative editing of a graphic in a collaborative document, and when a user edits the graphic (for example, a flowchart) in the collaborative document by using an editing terminal, a change process of the graphic can be presented on a following terminal accessing the collaborative document.

In some alternative implementations, the change instruction may be sent by the target server to the follower terminal by using a collaborative editing algorithm. If a plurality of persons edit the same flow chart in the collaborative document at the same time, the target server can solve the conflict by utilizing a collaborative editing algorithm, and the conflict can be solved without lock or user intervention by using the collaborative editing algorithm. The target server can solve the conflict generated by the fact that a plurality of editing terminals send the change instruction at the same time by using a collaborative editing algorithm through the following steps: in response to receiving change instructions sent by at least two user terminals, obtaining the receiving time of the at least two change instructions, wherein the user terminals comprise the execution main body; determining whether to modify the modification instruction based on the receiving time of the at least two modification instructions; and if so, correcting the change instruction, and sending the corrected change instruction to the following terminal. The target server may further determine whether to modify the modification instruction based on the reception times of the at least two modification instructions by: determining whether the receiving time of the change instruction sent by the execution main body is earlier than the receiving time of the change instruction sent by other user terminals; if not, the modification instruction is modified.

As an example, if a process graph block exists in a current collaborative document, a user a and a user B edit a graph in the collaborative document at the same time, and if the target server first receives a change instruction sent by a user terminal a used by the user a: adding a decision graph block behind a first graph block in the collaborative document, and then receiving a change instruction sent by a user terminal B used by the user B: adding a data graphic block after the first graphic block in the collaborative document. If the execution subject is the user terminal B, and the receiving time of the modification instruction sent by the user terminal B is later than the receiving time of the modification instruction sent by the user terminal a, the target server generally needs to modify the modification instruction sent by the user terminal B to: a data graphical block is added after the second graphical block in the collaborative document. And then, the modified change instruction can be sent to the following terminal, so that the conflict problem is solved.

With further reference to FIG. 4, a flow 400 of yet another embodiment of a document sharing method is shown. The document sharing method is applied to an editing terminal and comprises the following steps:

step 401, in response to detecting an editing instruction for a graph in the collaborative document, acquiring data in a first data format corresponding to the graph.

If an editing instruction for a graphic in the collaborative document is detected, the execution subject may obtain data in a first data format corresponding to the graphic. Here, the data corresponding to the graphic may be data corresponding to an edited whole graphic. The first data format may be a data format for drawing graphics.

As an example, grapheiditor can be employed as the above-described graphic editor. The graphpaditor is an open source graphical editor. When the grapheiditor is used as a graphic editor in a collaborative document, the first data format is usually an XML format. If the graph editor is adopted, getgraph XML provided by the graph editor can be called to obtain XML-formatted data corresponding to the edited overall graph.

Step 402, converting the data in the first data format into the data in the second data format.

In this embodiment, step 402 may be performed in a manner similar to step 302, and is not described herein again.

Step 403, comparing the data in the second data format with the target data to obtain the change information of the graph in the collaborative document, and generating a change instruction including the change information.

In this embodiment, the execution subject may compare the data in the second data format with target data to obtain change information of a graphic in the collaborative document, and generate a change instruction including the change information. The target data may be data in a second data format corresponding to a graphic obtained by the user editing a graphic in the collaborative document last time. The data received this time is compared with the data received last time to obtain the data of the changed part of the graph.

Here, the change information may include a change type of the graphic, for example, addition, deletion, or modification. The execution subject may generate a modification instruction corresponding to the modification type. The change instruction is generally used to instruct a change operation to be performed with respect to the graphics in the collaborative document.

As an example, the executing agent may determine the difference between the Data received this time and the Data received last time by using the open source library "just-diff" and convert the difference into an op in a Data-SDK based on a collaborative editing algorithm, where the op may make the Data go from one state to another, for example, the op from 'abc' to 'abcd' is insert ('d',3), i.e., a character d is added after the third character.

And step 404, sending a change instruction to the following terminal through the target server.

In this embodiment, step 404 may be performed in a manner similar to step 304, and will not be described herein again.

As can be seen from fig. 4, compared with the embodiment corresponding to fig. 3, the flow 400 of the graph modification method in this embodiment represents a step of comparing the data received this time with the data received last time, so as to generate a modification instruction. Thus, the scheme described in the present embodiment provides a method of determining a graphics alteration section, so that an alteration instruction can be accurately generated.

With continued reference to FIG. 5, a flow 500 of yet another embodiment of a method of graphical modification is shown. The graph changing method is applied to the following terminal and comprises the following steps:

step 501, in response to receiving a change instruction for a graph in the collaborative document, changing data in a second data format corresponding to a current graph in the collaborative document by using change information included in the change instruction to obtain changed data in the second data format.

In the present embodiment, the execution subject of the graphic change method (e.g., the follower terminal shown in fig. 1) may determine whether a change instruction for the graphic in the collaborative document is received. The collaborative document may also be referred to as a shared document or an online document, and generally refers to a document tool used online in a browser, and is characterized in that the content written by the document is automatically saved in real time, and multi-person collaborative editing is supported, that is, multiple persons are supported to edit the same document at the same time. The graphics may include, but are not limited to: a flow chart and a UML diagram.

If the change instruction is received, the execution main body may change the data in the second data format corresponding to the current graph in the collaborative document by using the change information included in the change instruction, so as to obtain the changed data in the second data format.

Here, a built-in "graphic editor" may exist in the collaborative document, and a user may edit a graphic in the collaborative document as needed by using the "graphic editor", and the edited graphic may exist in the document in the form of an SVG picture, so that a reader of the document may conveniently read the graphic.

As an example, grapheiditor can be employed as the above-described graphic editor. The graphpaditor is an open source graphical editor. Collaborative editing for graphics can be realized by using a collaborative editing algorithm on the basis of the grapheiditor. The collaborative editing algorithm can automatically resolve conflicts when multiple people edit the flow chart. When a collaborative editing algorithm is adopted for data collaboration, the second data format may be a JSON format.

Step 502, converting the changed data in the second data format into data in the first data format.

In this embodiment, the execution body may convert the modified data in the second data format into data in the first data format.

As an example, when the grapheiditor is used as the graphic editor in the collaborative document, the first data format is usually an XML format. The execution body may convert the modified JSON-formatted data into XML-formatted data. The execution body may analyze the modified JSON formatted data. For example, the execution body may fill each content in the data in the JSON format into a corresponding position in the template in the XML format according to a preset positional relationship, so as to obtain the data in the corresponding XML format.

Step 503, changing the graph in the collaborative document by using the data in the first data format.

In this embodiment, the execution body may modify the graphics in the collaborative document by using the converted data in the first data format. As an example, if the graphpatter is used as the graphic editor, the execution body may call setGraphXML provided by the graphpatter to present the graphic indicated by the data in the first data format in the current graphic, so as to modify the graphic in the collaborative document.
