Description

Technical Field

[0001] This invention belongs to the field of OFD document technology, specifically an OFD document barcode and sticky note pasting and reading device. Background Technology

[0002] Existing technologies for enhancing the interactivity of fixed-format documents such as OFD (Open Document Format) have limitations. Traditional methods often directly embed or modify additional information such as annotations and links into the original file, leading to: Document contamination and standardization: The original document content is modified, affecting its integrity and immutability as an official document or legal document. Limited and isolated functionality: Existing annotation or link functions are mostly static and unidirectional, lacking support for complex business processes, dynamic data associations, and multi-user collaboration. Difficulty in information traceability and management: Embedded content is tightly coupled with the original file, making it difficult to independently perform security verification, version management, and usage tracking of enhanced information. Lack of combination and reuse capabilities: The relationships between documents and document-based collaborative processes cannot be effectively preserved, encapsulated, and reused, forming information silos. Summary of the Invention

[0003] The purpose of this invention is to provide an apparatus for affixing and reading OFD document barcodes and sticky notes, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an OFD document barcode and note pasting and reading device, including a document conversion module, a content enhancement module, a data security module, a collaboration and combination management module, and a communication distribution and integration module. The file conversion module is used to convert files into a unified standard OFD format; The content enhancement module is used to perform enhancement operations on OFD files, including generating smart barcodes and multimodal notes; and assembling the generated content into XML format data. The data security module is used to save the operation content in the content enhancement module to an external extended file and digitally sign the file; The collaboration and combination management module is used for unified management of OFD files; The communication distribution and integration module is used to securely distribute the OFD files of the enhanced barcode and integrate intelligent barcode generation, note reading and writing, and task status query into third-party systems for external system integration.

[0005] The content enhancement module includes generating smart barcodes and multimodal notes; the process of generating smart barcodes is as follows: a. In the OFD editor, select the location where you want to insert the barcode; b. Enter or select the target information to be associated with the barcode; c. Instead of encoding the target information into a barcode, a dynamic mapping relationship is generated; d. Encode the redirected links generated in the previous step into QR code or barcode image data; e. Store in an XML extension file.

[0006] The process of creating the multimodal sticky notes is as follows: a. Select the target area, drag to resize the selection, and set the background color; b. Create content using multiple modes; c. Extract features from the original content and calculate its multi-dimensional identifier ID; d. Convert the collected raw heterogeneous data into a standardized format, in which text content is marked according to the standard format, handwritten handwriting is encoded into vector format, and audio and video files are compressed and encoded to generate access links and metadata.

[0007] The attributes of the multimodal notes are divided into: action-oriented, information supplement, interactive feedback, announcement / notification, and format carrier. The action-oriented categories are: tasks and circulation. Tasks, at their core, are about "doing": including specific to-do items, executors, and deadlines. Circulation, at its core, is about "reading": instructing or requesting specific people to read certain information. Information Supplementation Category: Supplementation, Interpretation, Knowledge Definition, and Related Extension; Supplementation refers to adding additional factual or supporting information, data, or cases; Interpretation refers to explaining, translating, or clarifying complex, ambiguous, or professional content; Knowledge Definition refers to providing clear explanations or standard definitions for key terms and concepts; Related Extension refers to establishing connections between current information and other information, scenarios, or knowledge, broadening the context; Interactive feedback refers to expressing personal opinions, questions, or evaluations of content, with the aim of initiating or participating in discussions; Announcements and notices refer to the release of information related to a specific document, and are a one-way information release. The carrier category refers to: sticky notes that support text, images, audio, video, and charts; used to present tasks and annotations.

[0008] The multiple modes of content creation include text or rich text mode, handwriting mode, audio / video mode, application mode, and knowledge base mode; If it is in text or rich text mode, the text editor will be launched and keyboard input will be recorded; If it is in handwriting mode, the handwriting device engine is activated to capture the coordinate sequence, strokes and timestamps of the handwriting at a millisecond sampling rate: the strokes are recognized as text and used as hidden attributes of the tag for the retrieval and analysis of the notes. If it is in audio / video mode, the device media API is called to record, and audio streams, video frames and possible screen annotation trajectories are captured simultaneously, or external audio / video files are imported. If the AI ​​extraction mode is enabled, the system performs real-time semantic analysis on the original context content captured in the first step, extracts key entities, obligations and potential risks, and generates a structured summary draft, which is displayed in the form of a list of key points.

[0009] If it is in application mode, the external application will be loaded as a link, supporting direct embedded loading and access within the reader, and loading and retrieving the content that the user wants to push. In the knowledge base mode, the system automatically performs intelligent analysis of the large model based on the information and content of the approvals under various modes. If it is an instruction or opinion, a knowledge base of instructions and opinions is generated. Users can use AI to reuse, summarize, search, categorize, statistically analyze, and distribute the instructions and opinions. If a knowledge base is generated, a knowledge base is generated for various notes on the document to produce applications. The notes are encapsulated into MPC intelligent agents for document expansion.

[0010] When extracting the original content, the document's logical structure is analyzed simultaneously, and the annotation content is mapped to logical nodes. Logical nodes include chapter titles, figure numbers, and clause indexes. An anchor descriptor is generated, which contains composite information of identifier ID, logical node ID, and physical coordinates.

[0011] Preferably, the data storage and security module saves the generated barcode logic content and note content in the OFD extended file. At the same time, when saving the file, a digital certificate is used to digitally sign the original OFD file and the external enhanced data respectively.

[0012] Preferably, in the collaboration and combination management module, the process of incorporating documents into a unified directory management system is as follows: Build collaborative data lists; without changing the current OFD layout file, establish reference links or enhance and expand upon other documents within the project, and enable combined reference reading of documents; combined reading refers to the system providing a combined reading view based on document reference relationships, allowing users to jump to, view, or compare referenced documents while reading the current document; task and workflow attachment refers to creating tasks for files or specific annotations within files, assigning responsible persons, setting deadlines and priorities, and linking task status with document content to achieve lightweight workflow collaboration based on documents.

[0013] Preferably, the main process of OFD file distribution with enhanced barcodes in the communication distribution and integration module is as follows: barcode scanning and intelligent routing; real-time status and synchronous notification; the barcode scanning and intelligent routing means that when a user scans the barcode on the file, the request first reaches the system redirection service, and the service dynamically parses and jumps to the final target or returns the associated enhanced information after verifying the permission and access policy according to the token; the real-time status and synchronous notification means that when the enhanced data of the document changes, the system can notify relevant collaborators in real time through integrated message push and communication methods.

[0014] External system integration refers to the integration of the OFD file itself with API function interfaces to integrate intelligent barcode generation, note reading and writing, and task status query functions into third-party office systems, document management systems, or business platforms, thereby horizontally expanding the file's capabilities.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) This invention integrates the leader’s instructions, the manager’s thoughts, the elements of execution, the scale, or the user’s wishes such as the information to be known and quick reading of relevant documents into the document through deep integration of sticky notes and OFD documents. This allows users to have more flexible expansion space while ensuring the purity and compliance of the original document. Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example

[0017] To enhance interactivity of fixed-format documents such as OFD files, this invention provides a device for pasting and reading OFD file barcodes and notes, including a file conversion module, a content enhancement module, a data security module, a collaboration and combination management module, and a communication distribution and integration module. The file conversion module converts various file formats, such as Word, PDF, and images, into the standard OFD format. The system then assigns a unique identifier to the newly generated OFD file, providing a unified and traceable object for all subsequent operations. Then, the content enhancement module is used to perform two core enhancement operations on the OFD file, including generating smart barcodes and multimodal notes; the main steps for generating smart barcodes are as follows: a. In the OFD editor, the user selects the location where the barcode will be inserted and obtains the page and coordinates of the insertion location; b. Enter or select the target information to be associated with the barcode. The target information can be a verification URL, a file ID of the associated combination, text content, or a smart agent link for intelligent parsing. c. Encode the target information into a barcode to generate a dynamic mapping relationship; d. Encode the redirect link generated in the previous step, for example: https: / / ofd-smart.com / v1 / r?token=..., into a QR code or barcode image data; e. Store in an XML extension file.

[0018] The main steps in creating a multimodal sticky note are as follows: a. When a user is reading or editing an OFD file, they can select a target area by clicking, dragging, or circling with the mouse, and then drag to adjust the size of the selection and set the background color. The system will capture the precise context of this interaction in a timely manner, including the target page number, area coordinates (such as the bounding box), and the original content within the area (such as text strings or image object IDs). b. The note area features an input panel where users can choose single or combined modes for content creation, or multiple modes for content creation. If text or rich text mode is selected, the system launches a text editor and records keyboard input. If handwriting mode is selected, the handwriting device engine is activated, capturing the coordinate sequence, strokes, and timestamps of handwriting at a millisecond sampling rate. Simultaneously, it recognizes the strokes as text, using them as hidden attributes of the tags for note retrieval, utilization, and analysis. If audio / video mode is selected, the device's media API is called for recording, and audio streams, video frames, and possible screen annotation trajectories are simultaneously collected, or external audio / video files are imported. If AI extraction mode is enabled, the system performs real-time semantic analysis on the original context content captured in the first step, extracting key entities, obligations, and potential risks to generate a structured summary draft. c. Extract features from the original content and calculate its multi-dimensional identifier ID. Simultaneously, analyze the document's logical structure and map annotation locations to the nearest logical nodes, such as chapter titles, figure / table numbers, and clause indexes. Finally, generate an anchor descriptor containing composite information of the identifier ID, logical node ID, and physical coordinates to ensure annotations are both resistant to layout changes and accurately positioned. d. The raw heterogeneous data collected in step b is converted into a standardized format. Text content is formatted according to tags such as HTML / JSON; handwritten handwriting is encoded into a compact vector format; audio and video files are compressed and uploaded to the storage service, generating access links and metadata; and AI summaries are organized into a list of key points. Subsequently, all these anchor descriptors generated in steps a and c, along with the automatically added metadata creator, timestamp, and globally unique ID, are assembled into a predefined XML format.

[0019] During system processing, the data security module saves the operations from the content enhancement module to an external extended file and digitally signs the file. Barcode logic and note content are not written to the OFD file itself, but are instead saved in a separate external extended file, `enhanced_data.xml`. This ensures the purity of the original file. Therefore, when saving the OFD file, both the original OFD file and the external enhanced data are digitally signed separately. This guarantees the immutability of the original document while ensuring the independence of the signature and the original document, conforming to official document standards.

[0020] The collaboration and combination management module provides unified management of OFD files. Users can create a project and manage multiple related documents, such as the main text, attachments, and supplementary agreements, within the same directory. Multiple related OFD documents can be added to the project, and the system maintains a document list for the current OFD file. A key feature is that it allows users to create reference links or enhance existing documents within the project without altering the current OFD layout. It also allows for combined document referencing: combined reading is based on document reference relationships, and the system provides a combined reading view, enabling users to easily jump to, view, or compare other related documents referenced by the current document. Task and workflow attachments allow users to create tasks for files or specific annotations / notes within files, assign responsibilities, set deadlines and priorities, and link task status with document content, achieving lightweight document-based workflow collaboration. During the distribution process, the communication distribution and integration module securely distributes OFD files with enhanced barcodes and integrates intelligent barcode generation, note reading and writing, and task status query into third-party systems. It supports secure distribution of OFD files with enhanced barcodes through various channels such as instant messaging tools and internal system notifications. Specifically, barcode scanning and intelligent routing: When a user scans the barcode on a document, the request first reaches the system's redirection service. The service verifies permissions based on the token, access policies such as validity period and maximum scan count, dynamically parses the request, and redirects the user to the final target. The final target may be a webpage, opening an associated file, starting an intelligent agent service, or returning associated enhanced information such as displaying annotation history. Real-time status synchronization and notification: When the enhanced data of a document changes, such as annotations being replied to or task status being updated, the system can notify relevant collaborators in real time through integrated push notifications and other communication methods. External system integration: Standard API interfaces are provided, allowing the integration of intelligent barcode generation, note reading and writing, and task status query functions into third-party office systems, document management systems, or business platforms to achieve capability expansion. Therefore, by combining the file conversion module, content enhancement module, data security module, collaboration and combination management module, and communication distribution and integration module, this system can combine the leader's instructions, the manager's ideas, the elements and standards of execution, or the user's wishes such as the information to be known from relevant documents and the ability to read quickly into the file. This allows users to have more flexible expansion space while ensuring the purity and compliance of the original documents.

[0021] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments are to be regarded in all respects as exemplary and not restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
