Description
Technical Field
The invention relates to the technical field of data processing, in particular to a digital object packaging and entity access method and system based on record playback.
Background
The basic element in the Digital Object architecture is the Digital Object (Digital Object), which is a uniform abstraction of any information system data resource. The digital object is divided into four parts: identification, metadata, state data, and entities. Wherein, the mark permanently and uniquely points to a digital object, and is the permanent and unchangeable attribute of the digital object; metadata is descriptive information of the digital object for retrieval and discovery of the digital object; the state data comprises information such as the current position, access entrance, access mode and the like of the digital object and is used for positioning and accessing the digital object; an entity is the actual content contained in a digital object and may be any sequence of bits or a collection of sequences of bits. The separation of the identification and status data also allows the identification of the digital object to no longer be tightly coupled to the location where the digital object is located, allowing the digital object to exist independently of the machine and not be inaccessible as the machine disappears, moves. DO is an abstraction of Internet resources, which represents a meaningful or valuable resource in the Internet. The representation of DO may be a sequence of bits, or a collection of sequences of bits; or may be a program that provides an interface to the outside. Just as each Host in the internet has an IP address as an identifier, each DO in the DOA also has an identifier for uniquely identifying the DO, and the identifier is called DOID. There are two basic protocols in DOA: identification/Resolution Protocol IRP (Identifier/Resolution Protocol) and Digital Object Interface Protocol DOIP (Digital Object Interface Protocol). There are three basic components in DOA, namely an identification/Resolution System (Identifier/Resolution System) responsible for identification and Resolution of the DO, a Repository System (replication System) responsible for storage and access of the DO entity, and a Registry System (registration System) responsible for registration of the DO meta information and search of the DO.
There are many end-users who desire to view digital objects (a uniform abstraction of arbitrary information system data resources). This requirement is often fulfilled by the access of a URL. However, in many scenarios, such as medical record systems in hospitals and OA systems in government offices, these business systems are usually single-page applications, data in the systems can only be presented in a web page and accessed by the most primitive human-computer interaction manner, the data can be reached only by manual page operations, and the traditional data addressing manner, such as URL, IP address, etc., is difficult to apply to such data.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the individual features of the embodiments can be combined with one another without conflict.
Referring to fig. 1, fig. 7 and fig. 13, fig. 1 is a flowchart of a digital object packaging and entity access method based on recording and playback according to an embodiment of the present invention, fig. 7 is a schematic diagram of a digital object addressing method based on recording and playback according to an embodiment of the present invention, and fig. 13 is a flowchart of packaging and access of a digital object packaging and entity access method based on recording and playback according to an embodiment of the present invention. The digital object packaging and entity access method based on record playback comprises the following steps:
step S100: collecting an interactive sequence of a user and Web application by using a record playback method, forming an interactive sequence script as an access path of a digital object to be packaged, and collecting URL (Uniform resource locator) of the Web application, page opening time and page title information as metadata of the digital object; and distributing a digital object identifier for the digital object to be packaged by the identifier analysis system, storing the metadata into a registry system, and storing the interactive sequence script serving as the access path into a digital object warehouse system to complete the packaging of the digital object, wherein the digital object comprises a digital object entity.
Step S110: and acquiring the identification of the digital object to be accessed, and analyzing the identification of the digital object to be accessed to obtain the corresponding user interactive sequence script. The user-interactive sequence script is obtained by recording user operations in pages for accessing web pages to be packaged as digital objects.
The method is applied to a scene that a digital object in a single-page application is browsed by an end user, in the scene, the method for touching the data resource is only operated in a page, and in order to access the data resource in the scene, a system page with rendered relevant data can be used as a digital object entity, so that the problem that the data entity leaves the system possibly is avoided. When data access is carried out, the data resource can be obtained by accessing the digital object, the access behavior is not carried out by a program any more but carried out by a user, the user only contacts with the front end of the web application, and the behavior of the user for viewing the data in the page is the access behavior of the digital object.
In order to support the above access behavior, a matching addressing method needs to be provided, that is, the stored address needs to be able to accurately locate the corresponding page state when the digital object is packaged, and the page rendering information in this state is the digital object entity.
To meet the above-described need for a digital object entity addressing method, recording of the page state may optionally be accomplished using recording and playback of browser operations. By recording the user operation path, an operation sequence script, namely a user interactive sequence script, is obtained, so that the problem of state transition of the single-page application can be effectively solved, and the state positioning can be completed on the premise of not storing data in the single-page application. Meanwhile, the restoration of the page state can be realized by a method of replaying the script.
Therefore, before addressing access to the digital object entity by adopting the method, the page to be accessed needs to be packaged into the digital object. Referring to fig. 2, fig. 2 is a flowchart of digital object generation according to an embodiment of the present invention. Digital object generation may be the recording of the process of using a Web application and the selection of content in a Web page to generate a digital object for a data entity. Before analyzing the digital object identifier to be accessed to obtain the corresponding user interactive sequence script, the method also comprises the following steps:
step S111, when detecting that a user accesses a webpage to be packaged as a digital object, generating a digital object generation request; the digital object generation part can comprise three processes, namely user starting recording, user interoperating with the Web application, and user selecting an interface to generate the digital object. Referring to fig. 3-4, fig. 3 is a sequence diagram of user start recording according to an embodiment of the present invention, and fig. 4 is a sequence diagram of user operation according to an embodiment of the present invention. The user starts recording, namely the user opens a plug-in, inputs a URL (uniform resource locator) for accessing a website, then the plug-in activates a back-end event monitor, after the plug-in is ready, the website to be accessed is opened by the plug-in, and the user starts to access. The method for the interoperation between the user and the Web application means that after the user finishes one operation, the plug-in records related operation information and sends the updated script to the rear-end event monitor, after the rear-end event monitor finishes processing the script, the plug-in updates the recorded information, the recording of one operation is finished, and the user can continue to operate normally. When accessing the webpage to be packaged as the digital object, the user opens the plug-in on the selected interface, selects to generate the digital object, and accordingly generates the digital object generation request.
Step S112, according to the digital object generation request and the webpage to be packaged as the digital object, packaging the user interactive sequence script, and distributing the digital object identification to obtain the digital object; the method comprises the steps of using a user interactive sequence script as an address of a data resource corresponding to a digital object, using a webpage to be packaged into the digital object as a digital object entity, collecting a Web application URL, page opening time and page title information as metadata of the digital object, distributing a digital object identifier for the digital object to be packaged through an identifier analysis system, storing the metadata into a registry system, and storing the interactive sequence script serving as an access path into a digital object warehouse system to complete the packaging of the digital object. Referring to fig. 5, fig. 5 is a sequence diagram of a user generated digital object according to an embodiment of the present invention. The specific process for encapsulating may be: and after receiving the request for generating the digital object, the back-end event monitor arranges the script content, then sends the script to an identifier analysis system, analyzes the returned value to obtain the digital object identifier, and returns the digital object identifier to the plug-in to complete the generation of the digital object. The interactive sequence script obtained by recording user operation can be stored in the digital object warehouse as the address of the data resource corresponding to the digital object, and when the user wants to access, the data resource corresponding to the digital object is found by a path playback method according to the address stored in the digital object warehouse for accessing.
The identifier in the digital object is a permanent and unique attribute that points to a digital object and is a permanent attribute of the digital object. The identification analysis system analyzes the digital object identification to obtain a warehouse where the digital object entity is located, and then the warehouse finds the specific position of the digital object entity through a corresponding addressing method to complete the access of the digital object entity. Therefore, when the digital object entity is addressed, the digital object identifier to be accessed is acquired first, and then the digital object identifier to be accessed is analyzed to obtain the corresponding user interactive sequence script. Specifically, the user inputs the identifier of the digital object to be accessed in the plug-in, the plug-in transmits the identifier to the back-end event listener, and the back-end calls the identifier resolution system to obtain the script corresponding to the identifier of the digital object to be accessed and returns the script to the plug-in.
Step S120: and taking the corresponding user interactive sequence script as an address used in path playback, and performing path playback to obtain a Web application interface of the digital object entity. The path playback is to obtain the recorded interactive sequence script through the digital object identification, and then to complete the simulation of the interoperation sequence of the user and the single-page application through the script, find the corresponding page state, and complete the support of the access. Referring to fig. 6, fig. 6 is a sequence diagram illustrating a user parsing a digital object according to an embodiment of the present invention. Specifically, the implementation can be that a user inputs a digital object identifier in the plug-in, the plug-in transmits the identifier to the back-end event monitor, the back end calls the identifier analysis system to obtain a script corresponding to the digital object identifier, the script is returned to the plug-in, and the plug-in plays back the script to obtain a Web application interface for storing a digital object entity.
In the implementation process, by using a record playback method, an interactive sequence of a user and a Web application is collected, an interactive sequence script is formed to be used as an access path of a digital object to be packaged, and URL (uniform resource locator) of the Web application, page opening time and page title information are collected to be used as metadata of the digital object; and distributing a digital object identifier for the digital object to be packaged by the identifier analysis system, storing the metadata into a registry system, and storing the interactive sequence script serving as the access path into a digital object warehouse system to finish the packaging of the digital object. Then acquiring a digital object identifier to be accessed, and analyzing the digital object identifier to be accessed to obtain a corresponding user interactive sequence script; and then, taking the corresponding user interactive sequence script as an address used in path playback, and performing path playback to obtain a Web application interface stored in the digital object entity. The digital object entity addressing based on record playback realizes a man-machine interaction type digital object warehouse system, an addressing path is recorded based on an interactive sequence script, addressing and access of the digital object entity in single-page application are completed in a path playback mode, and the problem of single-page application data touch is solved. The method has the advantages that the recording of the page state is realized by recording and replaying the browser operation, an operation sequence script is obtained by recording the user operation path, the problem of state transition of the single-page application can be effectively solved, and the state positioning can be completed on the premise that data in the single-page application is not stored. The stored address can accurately position the corresponding page state when the digital object is packaged, the page rendering information in the state is the digital object entity, and then the simulation of page operation can be efficiently and accurately completed through a path playback method to obtain the stored page state so as to realize access.
In the process of realizing path playback, the following problems exist: the efficiency needs to be improved in path playback, recording all interoperations of a user and performing playback completely is very inefficient, and a method needs to be found to reduce the number of operations for playback and improve the playback efficiency. In order to solve the above problem, a script compression process is added in the process of generating the digital object, please refer to fig. 8, where fig. 8 is a flowchart of a script compression algorithm provided in an embodiment of the present invention, which specifically includes the following steps:
firstly, extracting and taking DOM information of each operation in a page by a user as a DOM sequence of the user interactive sequence script. Document Object Model (DOM), the entire page element is collectively called DOM, which is essentially an interface (API) that is an API standard for manipulating web page content. The DOM is a platform and language neutral interface that allows programs and scripts to dynamically access, update the content, structure, and style of a document. One page is a document and is represented in the DOM by using document; all tags in the metapage are elements and are represented in the DOM by elements; all content in a page is a node (tag, attribute, text, annotation, etc.), represented in the DOM using a node; the DOM considers the above as one object and is therefore called the document object model.
Then, a key operation sequence in the user interactive sequence script is extracted. The key operation may be a preset operation, such as clicking, double-clicking, keyboard input, message sending, and the like. By combining these key operations, a key operation sequence is obtained.
And then, extracting the page element corresponding to the last key operation from the user interactive sequence script, and searching the corresponding page element in the DOM sequence of the user interactive sequence script to obtain matched DOM information.
The operation in the user interactive sequence script corresponds to the transition of the page state, and when the compression of the script is to be realized, the triggering of the state transition needs to be judged at first. By designing the interactive script, user behaviors can be defined, the user behaviors which may trigger state transition are taken as key operations and brought into the consideration range of script compression, wherein the key operations comprise clicking, double clicking, keyboard input, message sending and the like, and the key operations can be specifically preset according to actual needs. Focusing on these operations and selecting valid ones from them, the compression of the script can be realized.
The information in the script only determines when the state has completed the transition, but does not help the algorithm determine whether the conditions for the state transition are met. Therefore, in order to determine whether the condition of the state transition is satisfied, after each operation performed by the user, the DOM information of the page is pulled at the same time. Whether the operation sequence can be compressed is judged by judging the change of the DOM brought by each operation, namely judging whether the key operation related elements appear in the DOM.
Then, extracting a corresponding key operation script according to the matched DOM information, and taking the corresponding key operation as the last key operation; and recursively extracting the page elements corresponding to the last key operation according to the sequence of the key operations from back to front.
And finally, obtaining a compressed user interactive sequence script according to the corresponding key operation script extracted each time, and taking the compressed user interactive sequence script as the address of the data resource corresponding to the digital object.
During the course of a user's operation, the warehouse system has collected DOM information after each operation. After receiving the user interactive sequence script, extracting the page element corresponding to the last operation, sequentially searching the page element in the DOM of the script sequence, and recursively searching the element corresponding to the operation by taking the page element as the last operation, thereby realizing the compression of the script.
Some page state transitions depend on not a single operation, for example, a search operation includes inputting and clicking a button twice to complete a correct state transition. Therefore, before compression, it is necessary to check whether the current critical operation depends on the previous operation, and bind the operation with the dependency before compression. That is, in the above compression process, after finding the corresponding page element, it may check whether there is an operation dependency (for example, input and then search), and then recursively find the element corresponding to the operation again with this as the last operation, thereby implementing the compression on the script.
For example: an official chinese document is used as a test, which is a tree structured single page application that views different parts of the document by clicking on the tag on the left side of the page. The following is a partial program code:
{
"id": "62e38f50-30f1-4654-b873-78c797963dbd",
"command": "click",
"target": linkText =2.4. Gradually explain the test code ",
"targets": [
[ "linkText =2.4. Stepwise interpretation of test code", "linkText" ],
["css=.toctree-l2:nth-child(4) > .reference", "css:finder"],
[ "xpath =// a [ contacts (text (), '2.4. Stepwise interpretation of test code') ]," "xpath: link" ],
["xpath=//a[contains(@href, '#id6')]", "xpath:href"],
["xpath=//li[4]/a", "xpath:position"],
[ "xpath =// a [ contacts (, '2.4. Stepwise interpretation of test code') ]," xpath: innerText "]
],
"value": ""
}
As can be seen from the above codes, the last operation of the operation sequence is to click on the label of "2.4. Gradually explain the test code", and it is desired to view the contents of section 2.4. Our algorithm looks for script from front to back, and when checking the DOM after the user clicks the "2. Quick entry" tag, we find that the "2.4. Stepwise interpretation test code" this < a > tag is loaded for the first time, corresponding exactly to the script element under record. The algorithm identifies that the preconditions for enabling the operation in code 2.3 are the completion of the click "2. Quick entry" tag, thus completing a search and recursively looking for the preconditions for the click "2. Quick entry" tag. The label code loaded for the first time after clicking the label of '2. Quick entry':
< li class = "toctree-l2" > < a class = "reference internal" href = "# id2" >2.1. Simple use case </a > </li >

It can be known from the above codes that the operated element is loaded after a specific preamble operation and is recorded and searched by an algorithm. The tag is a tag type widely existing in HTML (hypertext markup language), and by positioning xpath information of the tag and css information of the element, the corresponding element can be accurately found, and the search algorithm is realized.
In the implementation process, the script compression is carried out on the user interactive sequence script, so that the number of operands contained in the finally packaged script is reduced, the access page can be obtained more quickly during playback, and the playback speed is improved. Meanwhile, the storage space required by the compressed user interactive sequence script is reduced, and the utilization rate of the storage space is improved.
In implementing the path playback, there are also the following problems: different operation sequences may reach the same page state, and if not processed, the different operation sequences may be encapsulated into different digital objects, and in fact, the data resources corresponding to the digital objects are the same. Therefore, it is desirable to package these different sequences of operations into the same digital object. For the above problem, after the script compression is performed, the script normalization processing may be performed, which specifically includes the following steps:
firstly, constructing a compressed DOM tree of the user interactive sequence script according to the DOM information of the last operation of the user in the page. Referring to fig. 9, fig. 9 is a schematic diagram of a DOM tree structure according to an embodiment of the invention. Since the DOM contains information such as documents, nodes, elements, etc., a DOM tree structure can be built based on the information. The DOM tree structure sequentially comprises child nodes, non-leaf nodes and root nodes from bottom to top.
Since the information in the script cannot determine the page state, the script normalization process also needs to pull the DOM information of the web page as the operated information and as the basis of the state. The script normalization algorithm is used for comparison among the scripts, the scripts which pass through different operation paths but reach the same DOM are distinguished according to the number of operands, and the scripts with less operation are used as a common operation sequence of the scripts and the scripts, namely the digital object addresses.
Then, respectively calculating the hash value of each compressed user interactive sequence script DOM tree; in order to determine whether the DOMs are the same, the hash values of the DOM trees of the compressed user-interactive sequence scripts may be compared to determine, and when the hash values of the DOM trees of the two compressed user-interactive sequence scripts are the same, it is determined that the DOMs reached by the two compressed user-interactive sequence scripts are the same.
And then, establishing association between the hash value of each compressed DOM tree of the user interactive sequence script and corresponding DOM information and corresponding digital object identification, and screening out compressed user interactive sequence scripts which have different operation paths but reach the same DOM according to the hash value of each compressed DOM tree of the user interactive sequence script.
Referring to fig. 10, fig. 10 is a schematic diagram of a hash tree structure according to an embodiment of the present invention. The screening is to compare the hash values of the DOM trees of the user interactive sequence scripts, and for simple and efficient comparison, when the hash values of the DOM trees are calculated, the hash values can be calculated one by one from child nodes to parent nodes. The hash value of a child node is the hash value of the name of the node. For a non-leaf node, when calculating the hash value, firstly, all child nodes are sorted according to the lexicographic order of the hash value, then all the hash values are taken as character strings to be connected, then the name of the node is connected, and then the hash value of the new character string is calculated to be used as the hash value of the node. Thus, the hash value of the root node can be finally calculated by calculating upwards layer by layer. And taking the hash value of the root node as the hash value of the whole DOM structure.
After the hash values of the DOM trees of the compressed user interactive sequence scripts are obtained through calculation, the user interactive sequence scripts with the same hash value are divided into a group, and therefore the compressed user interactive sequence scripts which have different operation paths and reach the same DOM are screened out.
And then, taking the compressed user interactive sequence script with the least operation in the compressed user interactive sequence scripts with different operation paths and reaching the same DOM as a normalized user interactive sequence script, and taking the normalized user interactive sequence script as the address of the data resource corresponding to the digital object.
In the implementation process, the compressed user interactive sequence scripts are further normalized, so that the user interactive sequence scripts which pass through different operation paths and reach the same DOM all adopt a common operation sequence, the digital object is conveniently packaged in a later period, and the storage space is saved. Meanwhile, because the common operation sequence is the least operation in the user interactive sequence scripts, the corresponding page can be found more quickly during path playback, and the path playback efficiency is further improved.
The script compression and the script normalization performed in the process of generating the digital object may be independent, that is, only the script compression processing or only the script normalization processing is performed in the process of generating the digital object, or the script compression and the script normalization processing may be performed in sequence, which is not limited in this embodiment.
The process of only performing script normalization processing comprises the following steps:
firstly, constructing a DOM tree of a user interactive sequence script according to DOM information of the last operation of a user in a page; then respectively calculating the hash value of each user interactive sequence script DOM tree; then, establishing association between the hash value of each user interactive sequence script DOM tree and corresponding DOM information and digital object identification, and screening out user interactive sequence scripts which have different operation paths but reach the same DOM according to the hash value of each user interactive sequence script DOM tree; and finally, taking the user interactive sequence script with the least operation in the user interactive sequence scripts with different operation paths and reaching the same DOM as the normalized user interactive sequence script, and taking the normalized user interactive sequence script as the address of the data resource corresponding to the digital object.
The step of respectively calculating the hash value of each user interactive sequence script DOM tree comprises the following steps: calculating hash values of sub-nodes in a DOM tree of the user interactive sequence script; calculating the hash value of a non-leaf node according to the hash value of the child node in the DOM tree of the user interactive sequence script; and calculating to obtain the hash value of the root node according to the hash values of the non-leaf nodes, and taking the hash value as the hash value of the user interactive sequence script DOM tree.
The process of the script normalization process can be known as follows: the process of performing only script normalization is the same as the process of performing script normalization after script compression, except that the process of performing only script normalization is performed for the user interactive sequence scripts, and the process of performing script normalization after script compression is performed for the compressed user interactive sequence scripts, so the description is omitted here.
