Description

Technical Field

[0001] The present invention relates to the technical field of computer information management, in particular to a document dynamic numbering method. Background Art

[0002] Existing document numbering technologies mostly use sequential coding or storage path-based coding.

[0003] For example: Sequential coding: Relying on a central database to generate incremental serial numbers, it presents a single point of failure risk and has poor horizontal scalability. Hash coding: Generates a unique identifier based on file content, but has high computational overhead and cannot reflect business logic; Storage-bound coding: For example, numbering based on the file storage path (e.g., / server1 / doc / 001) requires renumbering during document migration, disrupting inter-system compatibility. Furthermore, existing technologies generally lack support for dynamic rule engines, making it impossible to adjust numbering strategies in real time based on business scenarios. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for dynamic document numbering in response to the above-mentioned problems in the prior art, thereby solving all or one of the above-mentioned problems in the prior art.

[0005] In order to solve the above technical problems, the specific technical solutions of the present invention are as follows: The present invention provides a method for dynamic document numbering, comprising: The rule parsing module loads a numbering template containing a timestamp variable timestamp and a business classification code {category}; The metadata extractor extracts the author ID, creation date, and document type triples from the document header; The conflict detection engine uses Bloom filters for pre-judgment and re-processing; The distributed lock service implements atomic allocation of multi-node numbers based on the Raft protocol.

[0006] As an improved solution, the numbering template supports dynamic variable injection, including: The geographic location variable ${geo_code} is automatically populated through the IP address resolution service; The version iteration variable ${version} is generated in the format of major version, minor version, and revision number; Random anti-collision code ${random8}, generates an 8-bit Base64 encoded string.

[0007] As an improved solution, the operations performed by the metadata extractor further include: Extract from the XMP metadata block of a PDF document <dc:creator>Field; Enable the OCR recognition module for documents without metadata to parse the issuing unit's signature on the title page; Generate metadata fingerprint in SHA-256 format and store it in an independent key-value database.

[0008] As an improved solution, the prejudgment reprocessing includes: First level validation: local Bloom filter quickly screens for potential duplications; Second level verification: distributed consistent hash ring comparison of cluster node metadata; Level 3 verification: The blockchain evidence storage service verifies the historical number records.

[0009] As an improved solution, the distributed lock service includes: The write-ahead log persists all numbered requests; The lease mechanism sets a 10-second validity period, which will be automatically released after the timeout. When a node fails, lock migration is triggered through heartbeat detection.

[0010] As an improved solution, it also includes: When the document content is updated, the original number is retained and a version suffix is appended; Establish a version graph database to record the difference hash values between versions; Automatically triggers filing number reorganization for documents with more than 5 revisions.

[0011] As an improved solution, it also includes: Call the file path redirector to map the logical number to the physical storage path; Call the storage performance monitor to dynamically adjust the number allocation strategy based on I / O latency.

[0012] As an improved solution, the method supports multi-user isolation: Generate an independent namespace through the user ID ${tenant_id}; Each user configures an independent rule cache pool; Data storage between users is isolated using logical volume encryption.

[0013] As an improved solution, it also includes: When the storage system is detected to be unreachable, the local temporary number pool is enabled; After the network is restored, two-way synchronization is performed, using the Operational Transform conflict merging algorithm; Abnormal events are recorded in the audit log in the format of timestamp|event code|affected scope.

[0014] As an improved solution, the final numbering format is: ${geo_code}-${category}-${timestamp(yyyyMMdd)}-${random8}; each field is separated by a hyphen, and a Base58-encoded metadata fingerprint is attached as a check code.

[0015] The beneficial effects of the technical solution of the present invention are: the document dynamic numbering method described in the present invention can achieve improved numbering efficiency, decoupling of storage systems, support for maintaining numbering consistency during cross-platform migration, multi-dimensional conflict detection mechanism to reduce coding repetition rate, rule hot loading technology to achieve seamless switching of business strategies, and encrypted fingerprint embedding to enhance document traceability security.
