Detailed Description
Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The present disclosure provides a method of updating stored information of a document, the method including an object generation stage, an attribute value acquisition stage, and an information merging stage. In the object generation stage, in response to first annotation update information for adding annotations in a document, a first object for which annotations are to be added is generated based on the first annotation update information. In the attribute value obtaining stage, a first identifier in the first annotation update information is taken as a value of a target attribute of the first object. In the information merging stage, the first object is merged into the stored information of the document.
An application scenario of the method and apparatus provided by the present disclosure will be described below with reference to fig. 1.
Fig. 1 is an application scenario schematic diagram of a method, an apparatus, a device, and a storage medium for updating stored information of a document according to an embodiment of the present disclosure.
As shown in fig. 1, the application scenario 100 includes one or more terminal devices 111 to 112 and a database server 120, and the one or more terminal devices may communicate with the database server 120 through a network to obtain a document from the database server or store the edited and modified document in the database server 120. Wherein the network may comprise wired or wireless communication links.
The terminal devices 111-112 may be display screen-capable terminal devices capable of document editing, including but not limited to smart phones, tablet computers, laptop and desktop computers, and the like.
The database server 120 may be, for example, a server having a storage function. The server may be a cloud server, a server of a distributed system, or a server incorporating a blockchain.
According to embodiments of the present disclosure, one or more users may edit a document via the one or more terminal devices 111-112, for example, may add annotations to the document or modify existing annotations in the document. The one or more terminal devices may render the front-end display page in response to adding the annotation or modifying the existing annotation to display the document with the added annotation or modified the existing annotation to the one or more users. The one or more terminal devices may also send annotation update information to the database server 120 indicating that annotations are added or that existing annotations are modified, such that the database server 120 invokes the installed merge engine 140 to update the stored information of the document, add annotations to the stored information indicating that annotations are added, or perform modifications to the stored information indicated by the annotation update information, thereby obtaining a new document 150. The modification to the existing label may include adding the labeling content of the existing label, modifying the labeling content of the existing label, deleting the existing label, and the like, which is not limited in this disclosure.
In one embodiment, multiple users may collaboratively edit a document online. For example, a first user may add a first annotation 131 to a document via terminal device 111 and a second user may add a second annotation 132 to the document via terminal device 112. The terminal device may send annotation update information indicating that the first annotation is added and annotation update information indicating that the second annotation is added to database server 120. The database server 120 may respectively establish an object for the first annotation and an object for the second annotation based on the received annotation update information by invoking the merge engine 140, and merge the established objects into the storage information of the original document to obtain the storage information of the new document 150, thereby implementing the update of the storage content of the document. Wherein each object has a unique identifier and each object uniquely corresponds to a label. It is to be appreciated that online collaborative editing of documents may be implemented, for example, based on cloud platform technology and cloud storage technology, which is not limiting of the present disclosure.
According to the embodiment of the present disclosure, since the terminal device renders the display page at the front end, the database server 120 has not completed updating the stored information of the document, that is, has not generated the object corresponding to the newly added annotation. Then at the front-end rendering stage, the identifier of the object corresponding to the newly added annotation cannot be obtained. Typically, the terminal device generates a temporary identifier for the newly added label and carries the temporary identifier in the label update information to distinguish between different labels.
When the database server 120 updates the stored information of the document based on the annotation update information indicating that a certain annotation is added, the length required for the update may be long. In a practical scenario, during the updating process, the terminal device may receive an operation of modifying the certain label by the user, and send label update information indicating to modify the certain label to the database server 120. In this case, the database server 120 needs to change the object for a certain annotation based on the annotation update information indicating that the certain annotation is modified after completing the update based on the annotation update information indicating that the certain annotation is added. However, since the label update information indicating modification of the certain label carries a temporary identifier, the database server 120 first needs to solve the problem of how to associate the temporary identifier with the object for the certain label.
To solve the above problem, the above situation can be avoided by means of locking. For example, in a process in which the database server updates the document storage information based on the annotation update information indicating that a certain annotation is added, the document is locked so that the user cannot modify the existing annotation in the document. Or by locking, a user only adding a certain label has the authority to modify the certain label, so that the synchronization of the adding and modifying of the certain label is ensured to be realized at the same terminal. But in the case of editing a document cooperatively by multiple persons, editing efficiency and user experience are reduced to some extent.
In order to solve the above-mentioned problem, when receiving the label update information indicating that a certain label is added, the database server 120 may first establish a mapping relationship between the temporary identifier in the label update information and the identifier of the object for the certain label, so when the database server 120 modifies the label update information of the certain label, the object for the certain label may be located from the mapping relationship based on the temporary identifier in the label update information, thereby modifying the object based on the label update information for modifying the certain label. The method can solve the problems of low editing efficiency and poor user experience, but the complexity of updating the document storage information is increased because the mapping relation needs to be constructed in advance and needs to be read when the labels are modified each time.
In order to solve the above-described problem, a method of updating stored information of a document described below may also be employed, for example, when the database server 120 generates an object for an annotation to be added, the temporary identifier for the annotation to be added generated by the terminal device may be used as a value for a certain attribute in the object for the annotation to be added. So that the database server 120 can provide a basis for subsequently locating the object to be annotated.
It should be noted that, the method for updating the stored information of the document provided by the present disclosure may be performed by the database server 120. Accordingly, the means for updating stored information of a document provided by the present disclosure may be provided in the database server 120.
It should be understood that the number and types of terminal devices and database servers in fig. 1 are merely illustrative. There may be any number and type of terminal devices and database servers as desired for implementation.
The method of updating stored information of a document provided by the present disclosure will be described in detail below with reference to the scenario described in fig. 1, by way of fig. 2 to 4.
FIG. 2 is a flowchart of a method of updating stored information of a document according to an embodiment of the present disclosure.
As shown in fig. 2, the method 200 of updating stored information of a document of this embodiment may include operations S210 to S230.
In operation S210, in response to first annotation update information for adding annotations in a document, a first object for which annotations are to be added is generated based on the first annotation update information.
According to the embodiment of the disclosure, when the first annotation update information is received, if the database server does not update the document, the first object can be generated based on the first annotation update information in time. If the database server is performing an operation to update the stored information of the document, a first object may be generated based on the first annotation update information after the operation is performed.
According to embodiments of the present disclosure, the document may be a document stored in the form of an object, for example, a document in a portable document format (Portable Document Format, PDF), or the like. Wherein each element in the document is stored in the form of an object, and each object has a unique identifier (id value), which is an integer. In a PDF document, the identifier is used to cross-reference the storage location of a table index object.
The labels added in the document can be text box labels, highlight labels, underline labels or strikethrough labels and the like. By generating the first object and combining the first object into the stored information of the original document, the updated stored information can include the added marked information, and the stored information of the document is updated. It will be appreciated that the above-added labels are merely examples to facilitate an understanding of the present disclosure, and the present disclosure is not limited thereto.
According to an embodiment of the present disclosure, the first object is used to record related information of the added label, for example, an id value of the object, a label type, coordinates, color, line width, author information, creation time, modification time, and the like of the label may be recorded. The related information may be embodied in the form of attributes, for example, the first object may have a plurality of attributes that may include a presentation stream (APPEARANCE STREAMS), color, creation time, identifier, annotation Name (Name, NM), indirect referencing object, pop-up box object, default user space, element location coordinates in the annotation, location, type, and subtype of parent node, and so forth. The NM is an optional attribute, and is a string of characters for recording a label name, wherein the label name is unique in a document page to which the label belongs.
When the first object is generated, each piece of information in the first label updating information can be used as the value of each attribute in the first object, and the first label updating information can comprise the related information. It will be appreciated that the merging engine installed in the database server may be invoked to generate the first object, and the method of generating the first object is similar to the related art and will not be described in detail herein. The merging engine may integrate program modules for updating documents stored in the form of objects in the related art, which will not be described in detail herein.
In operation S220, the first identifier in the first annotation update is taken as the value of the target attribute of the first object.
According to embodiments of the present disclosure, the target attribute may be the NM described previously, or any other attribute. The first identifier in the first annotation update information may be a temporary identifier for the annotation to be added generated for the terminal device.
After the first object is generated, the first identifier may be read, for example, from the byte in which the identifier is recorded in the first annotation update information, and the read first identifier may be assigned to the target attribute of the first object. The byte of the record identifier may be determined according to a preset protocol, and the position of the byte is not limited by the present disclosure.
In operation S230, the first object is incorporated into the stored information of the document.
After the first object is obtained and the value of the first object is set, the first object can be added to the original storage information of the document stored in the database memory to form the storage information of a new document. Thereby realizing the updating of the stored information of the document.
The embodiment of the disclosure further assigns the temporary identifier generated by the terminal device to the target attribute of the first object after generating the annotation object for the to-be-added annotation based on the to-be-added annotation. In this way, the attribute of the first object includes both the attribute having the value of the identifier of the first object and the temporary identifier having the value of the identifier for the object to be marked. Thus, the association between the temporary identifier generated by the terminal equipment and the object can be realized without additionally establishing a mapping relation. Therefore, the updating efficiency of the stored information of the document can be improved to a certain extent, and the complexity of a system engine for updating the stored information in the database server is reduced. Moreover, in the embodiment, the association between the temporary identifier generated by the terminal equipment and the identifier of the object can be established by assigning the attribute of the object, so that the technical scheme that the temporary identifier cannot be corresponding to the object is solved without locking, and the file editing efficiency and the user experience can be improved.
By the method for updating the stored information based on the first annotation update information added with the annotation in the document, when the annotation update information for modifying the annotation in the document is received later, the object aiming at the document to be modified can be positioned according to the identifier of the object and the temporary identifier in the target attribute of the object, so that the accurate modification of the annotation is realized. The method of locating the object will be described in detail below in conjunction with fig. 3.
FIG. 3 is a schematic diagram of determining a second object for a annotation to be modified in stored information of a document according to an embodiment of the present disclosure.
According to the embodiment of the disclosure, when the annotation update information received by the database server is second annotation update information for modifying the annotation in the document, the embodiment can firstly determine a second object for the annotation to be modified in the storage information of the document.
In an embodiment, as shown in fig. 3, when determining the second object, the embodiment 300 may first determine the identifier in the second label update information 310 as the second identifier 320. A second object for the annotation to be modified in the stored information of the document is then determined based on the second identifier 320. The document may have, for example, at least one annotation, and accordingly the stored information of the document includes at least one object for the at least one annotation, respectively.
If the document displayed by the terminal device is an updated document obtained from the database server, the terminal device responds to the operation of modifying the annotation by the user, and the identifier carried in the annotation update request sent to the database server is an identifier for the object to be modified. Thus, in this embodiment, when determining the second object based on the second identifier 320, the identifier of at least one object (i.e., the object identifier 340) may be sequentially matched with the second identifier 320 to obtain the first matching result 350. Wherein the identifiers of the objects in the stored information 330 of the document may be traversed, and one identifier obtained by the traversing is matched with the second identifier 320 to determine whether the two are consistent. If the acquired identifiers are consistent, determining the object to which the acquired identifiers belong as a second object. If not, traversing and re-acquiring the other identifier, and matching the other identifier with the second identifier. Until the identifier of the object matching the second identifier is obtained, or the identifiers of all objects in the stored information of all documents are matched with the second identifier. Wherein the first matching result 350 may include having the object identifier matching the second identifier and not having the object identifier matching the second identifier. If the first matching result 350 is that there is a matching object identifier, the object to which the object identifier belongs is regarded as the second object 360.
Illustratively, if the first match result 350 is an identifier that does not have an object that matches the second identifier. It may be caused by the fact that the document displayed by the terminal device is not an updated document obtained from the database server, the terminal device not yet being aware of the identifier for the object to be modified. In this case, the identifier in the label update information sent by the terminal device is a temporary identifier generated by the terminal device for the label. The embodiment may also match the second identifier 320 with the value of the target attribute of the at least one object in case it is determined that the identifiers of the at least one object do not match the second identifier 320. Specifically, the value of the respective target attribute of the at least one object may be determined first. Then, the object to which the value of the target attribute matching the second identifier belongs is determined as the second object.
For example, the value 370 of the target attribute of the at least one object may be sequentially matched with the second identifier to obtain a second matching result 380. The target attribute of at least one object in the stored information of the document may be traversed to obtain a value 370 of the target attribute, and the value of the target attribute obtained by the traversing is matched with the second identifier to determine whether the value of the target attribute and the value of the second identifier are consistent. If so, the object to which the value of the target attribute obtained by the traversal belongs is determined to be the second object 360. If not, traversing and re-acquiring the value of the other target attribute, and matching the value of the other target attribute with the second identifier. Until a value of the target property matching the second identifier is obtained or a value of the target property of at least one object matches the second identifier. Wherein the second match result 380 may include values having target attributes that match the second identifier and values not having target attributes that match the second identifier. If the second matching result is that the value of the target attribute matched with the second identifier is not included, the second label updating information sent by the terminal equipment is possibly wrong, and the second label updating information can be selected to be discarded.
After determining the second object 360 for the annotation to be modified in the stored information of the document, the second object 360 may be modified based on the second annotation update information 310. For example, if the modification to the label to be modified is modification to the color of the label, modifying the value of the color attribute in the attribute of the second object. If the modification to the label to be modified is deleting the label to be modified, the second object can be directly deleted. By modifying the second object, updating of the stored information of the document can be achieved. It will be appreciated that the method of updating the stored information of the document based on the second annotation update information is similar to that of the related art and will not be described in detail herein.
As can be seen from the foregoing, when the second label update information for modifying the label in the document is received, and when the identifier of the object that matches the second identifier is not matched, the embodiment of the disclosure can determine the object for the label to be modified by matching the second identifier with the value of the target attribute of the object, without acquiring the mapping relationship first as in the related art, and then searching the object identifier having the mapping relationship with the second identifier from the mapping relationship based on the second identifier. Therefore, the efficiency of updating the stored information of the document can be effectively improved.
Fig. 4 is a schematic diagram of stored information of an update document according to another embodiment of the present disclosure.
According to the embodiment of the disclosure, when receiving the annotation update information sent by the terminal device, the database server can update the storage information of the document based on the annotation update information in time, for example, in an idle state. The annotation update information may be cached first, and the stored information of the document may be updated periodically based on the cached annotation update information.
Illustratively, the method of updating stored information of a document of this embodiment may cache third annotation update information in response to receiving the third annotation update. And then periodically updating the storage information of the document according to the cached third labeling updating information. The update period may be set according to actual requirements, for example, which is not limited in the present disclosure. It will be appreciated that the stored information of the update document of the previous embodiment is more advantageous in this periodically updated scenario.
According to an embodiment of the present disclosure, when periodically updating the stored information of the document, the embodiment 400 may first obtain the cached third annotation update 420 from the cache space 410. After the cached third annotation update 420 is obtained, the type of the cached third annotation update 420 may be determined. The types include a type of adding a label in the document and a type of modifying a label in the document. The stored information of the document is then updated based on the type of the cached third annotation update 420. It is to be appreciated that modifying annotations in a document can include deleting annotations in the document, adding, deleting, modifying, etc., content of annotations in the document.
For example, an information transfer protocol may be set between the terminal device and the database server, and the information transfer protocol may be defined with a target byte in the information indicating the type of information. This embodiment, in determining the type of the cached third annotation update 420, may determine the type based on the value of the target byte. For example, as shown in FIG. 4, after the cached third annotation update 420 is obtained from the cache space 410, the value 430 of the target byte in the cached third annotation update 420 may be determined. If the value of the target byte is 1, then the type 440 of the cached third annotation update may be determined to be the type of adding annotations to the document. If the value of the target byte is 0, then the type 440 of the cached third annotation update may be determined to be the type of annotation in the modified document. It may be understood that the target byte may be any byte in the third label update information, and the value of the target byte and the correspondence between the value of the target byte and the type of the third label update information are merely used as examples to facilitate understanding of the disclosure, which is not limited by the disclosure.
According to the embodiment of the disclosure, if the determined type 440 of the cached third annotation update information 420 is a type of adding an annotation in the husband, the cached third annotation update information may be used as the first annotation update information described above, and the operation performed in response to the first annotation update information is used to merge the object to be added with the annotation indicated by the third annotation update information into the storage information of the document, so as to complete the update of the storage information of the document.
