This policy explains how JLPCS seeks to preserve published articles, article metadata, supplementary materials, editorial notices, issue records, and journal-level publication information for long-term access and scholarly verification.

The policy is designed to support transparency, continuity of access, citation stability, metadata accuracy, digital preservation, and protection of the scholarly record.

本政策说明 JLPCS 如何保存已发表文章、文章元数据、补充材料、编辑通知、期号记录和期刊级出版信息，以支持长期访问和学术核查。本政策旨在保障透明度、访问连续性、引用稳定性、元数据准确性、数字保存和学术记录完整性。

JLPCS preservation efforts apply to official journal content and publication records made available through the journal platform.

Preserved materials may include:

• Final published articles in PDF, HTML, XML, or other available formats;
• Article landing pages and article-level metadata;
• Titles, abstracts, keywords, author names, affiliations, ORCID iDs, references, DOI records, and issue information;
• Supplementary files, appendices, datasets, code files, instruments, or methodological materials when published with the article;
• Corrections, retractions, expressions of concern, editorial notes, and other post-publication notices;
• Issue tables of contents, publication dates, licensing notices, copyright statements, and open access information;
• Journal policies, author instructions, peer review policies, ethics policies, APC information, and editorial information.

保存范围包括正式发表文章、文章页面、元数据、补充材料、出版后通知、期号记录、许可信息以及与期刊透明度有关的重要政策页面。

JLPCS maintains its official journal content through the journal website and publishing platform. Published articles are organized by article record, issue record, publication date, author information, metadata, and article files where available.

• Published articles are assigned article landing pages;
• Article files are made available through the journal platform;
• Issue records and tables of contents are maintained for published issues;
• Article metadata are maintained to support discovery, citation, and indexing workflows;
• Post-publication notices are linked to affected articles where applicable;
• Journal policies are maintained online and updated when necessary.

JLPCS 通过期刊网站和出版平台维护正式发表内容，包括文章页面、文章文件、期号记录、元数据、出版日期和出版后通知。

JLPCS seeks to maintain backup practices for published content, article metadata, journal files, and policy information to reduce the risk of accidental loss, platform disruption, or file corruption.

Backup and file management practices may include:

• Maintaining copies of final published article files;
• Maintaining records of article metadata, issue metadata, and publication dates;
• Retaining copies of post-publication notices and corrected files where applicable;
• Maintaining administrative records necessary for publication verification;
• Using secure platform-level or server-level backup procedures;
• Reviewing file availability and replacing corrupted or inaccessible files when identified;
• Restricting unauthorized modification of published files and article records.

备份和文件管理旨在降低误删、平台中断、文件损坏或记录丢失风险。正式发表文件和元数据应尽量保持可访问、可核查和可追溯。

Metadata preservation supports article discovery, citation, indexing, and long-term verification of the scholarly record. JLPCS aims to maintain complete and accurate metadata for published content.

Metadata may include:

• Article title, subtitle, abstract, keywords, and article type;
• Author names, affiliations, ORCID iDs, corresponding author information, and contribution information where available;
• Publication date, volume, issue, article number, page information, and DOI where assigned;
• References, funding information, conflict of interest statements, ethics statements, data availability statements, and AI use statements where applicable;
• License, copyright notice, article version, and post-publication status;
• Links to corrections, retractions, expressions of concern, supplementary files, and related materials.

元数据保存有助于文章检索、引用、数据库收录和长期核查。文章题名、作者、摘要、关键词、DOI、期号、许可、引用和出版后状态等信息应尽量保持准确。

Where DOI registration is provided, JLPCS maintains article-level DOI and metadata records to support stable citation, article identification, and long-term discoverability.

• DOI records should point to the official article landing page where applicable;
• Metadata should be updated when corrections, retractions, or other publication status changes occur;
• Article citation information should remain consistent across article pages, PDFs, metadata deposits, and issue records;
• Broken DOI links, metadata errors, or article record inconsistencies may be corrected when identified;
• Authors and readers may report metadata or DOI issues to the editorial office.

当文章配置 DOI 时，JLPCS 将通过文章级 DOI 和元数据记录支持稳定引用和长期识别。若发现 DOI、文章页面或元数据错误，可联系编辑部核查。

Supplementary materials published with an article may form part of the scholarly record. JLPCS seeks to preserve supplementary files when they are accepted for publication and made available through the journal platform.

Supplementary materials may include:

• Appendices, additional tables, figures, charts, and methodological notes;
• Datasets, codebooks, coding schemes, survey instruments, interview protocols, or analysis scripts;
• Legal source lists, policy documents, source selection tables, or comparative materials;
• Data availability documents, ethics documentation summaries, or reproducibility files where appropriate;
• Correction files or replacement supplementary files issued after publication.

补充材料如作为文章正式出版记录的一部分，应尽量与文章页面保持关联。涉及隐私、保密、法律限制或第三方权利的材料不得不当公开。

Corrections, retractions, expressions of concern, editorial notes, and other post-publication notices are part of the scholarly record and should remain linked to the affected article wherever possible.

• Correction notices should identify the article and explain the correction;
• Retraction notices should remain visible and linked to the retracted article where technically possible;
• Expressions of concern should remain linked while concerns are unresolved;
• Article files and metadata may be updated to show corrected or retracted status;
• Post-publication notices should not be removed merely because they are unfavorable;
• Access restriction may be considered only for legal, privacy, safety, or court-related reasons.

更正、撤稿、关注声明和编辑说明是学术记录的重要组成部分，应尽量长期保存并与原文章建立清晰链接。

JLPCS aims to maintain reasonable continuity of access to published content. If technical, organizational, or publishing changes affect the journal platform, JLPCS will seek to preserve access to the published record through appropriate content migration, backup restoration, metadata maintenance, or alternative access arrangements.

Continuity measures may include:

• Maintaining copies of final published article files and metadata;
• Migrating article records to an updated journal platform if necessary;
• Maintaining DOI and article landing-page redirection where technically possible;
• Preserving issue-level tables of contents and article lists;
• Maintaining access to correction, retraction, and expression-of-concern notices;
• Providing alternative access instructions if the journal platform is temporarily unavailable;
• Communicating major platform or preservation changes through the journal website where appropriate.

如期刊平台、技术系统或出版安排发生变化，JLPCS 将尽量通过内容迁移、备份恢复、元数据维护、链接重定向或替代访问安排保护已发表记录。

JLPCS may consider participation in recognized third-party digital preservation services, repository systems, institutional archiving arrangements, or preservation networks as the journal develops.

• Potential arrangements may include trusted digital repositories, national or institutional archives, LOCKSS, CLOCKSS, Portico, PKP Preservation Network, or other appropriate preservation services;
• Any active third-party archiving or preservation arrangement will be listed on this page when formally implemented;
• No service should be interpreted as active unless it is expressly named as active on this page or in an official preservation notice;
• JLPCS will avoid claiming indexing, archiving, or preservation participation that has not been confirmed;
• Future preservation arrangements may depend on technical compatibility, eligibility, cost, journal development, and publisher policy.

JLPCS 可根据期刊发展情况考虑接入第三方长期保存服务。除非本页明确列出为“已启用”或“active”，否则不应将任何服务名称理解为当前已加入的保存项目。

JLPCS seeks to maintain a transparent record of significant changes to published content. Formal corrections, retractions, expressions of concern, or editorial notes should be used when changes affect the scholarly record.

• Minor technical corrections may be made when they do not affect meaning, authorship, data, results, conclusions, or citation;
• Substantive changes should normally be documented through a formal correction or editorial notice;
• Article files may be replaced, labelled, or supplemented where necessary to reflect corrected or retracted status;
• Metadata should be updated when publication status changes;
• Older records should not be silently removed when they are necessary to understand the publication history;
• Authors and readers may report version inconsistencies to the editorial office.

涉及学术记录的重要变更应通过正式更正、撤稿、关注声明或编辑说明体现，不应通过静默修改掩盖影响文章理解的重大问题。

Authors, readers, libraries, repositories, and indexing services can support digital preservation by using correct citation information, reporting broken links, and respecting version status.

• Authors should cite and share the official published version of record;
• Authors should update preprint, working paper, institutional, or personal pages with the official JLPCS citation where possible;
• Readers should cite DOI, article title, journal title, year, volume, issue, and article page where available;
• Readers may report broken links, missing PDFs, incorrect metadata, or file access problems;
• Repositories should preserve article metadata, license information, and links to the official published version;
• Users should not redistribute outdated or retracted versions without clearly identifying their publication status.

作者、读者、图书馆和仓储平台可通过正确引用正式发表版本、报告链接错误、保留许可信息和标注文章状态，共同支持数字保存。

This policy is intended to describe JLPCS's preservation commitments and planning. It should not be read as a claim of current participation in any specific external archiving service, indexing database, repository, or preservation network unless that participation is expressly listed as active.
