Community and data policy

本站用于科研数据交流。元数据、贡献者、机构、曲线、结构及审核意见可公开浏览，包括待审核与未通过记录。下载权限限制原始文件和 ZIP，并不使预览数据保密。

只提交有权分享的实验与结构，不上传保密项目、个人敏感信息、第三方凭据或不允许再分发的资料。

This site supports scientific data exchange. Metadata, contributor names, institutions, patterns, structures and review notes are publicly browsable, including pending and not-approved records. Download approval controls files and ZIP archives, not preview confidentiality.

Submit only material you have permission to share. Do not upload confidential projects, sensitive personal information, credentials or data that cannot be redistributed.

贡献者应如实描述实验、来源和不确定性。管理员复核、XMatcher 候选和理论峰用于协助判断，不替代研究者的独立检验。未通过意见应针对数据，给出可以执行的修改建议。

Contributors should describe experiments, sources and uncertainty accurately. Human review, XMatcher candidates and calculated peaks support assessment but do not replace independent scientific validation. Feedback should address the data and offer actionable corrections.

提交时标注实际许可与来源；本政策不为所有记录自动授予统一许可。使用数据前核对记录和上游来源的许可，保留贡献者与原始文献引用。不清楚授权时先联系负责人。

State the applicable license and source when submitting. This policy does not assign one universal license to all records. Before reuse, check record and upstream terms, preserve contributor and publication attribution, and contact the project lead when permissions are unclear.

账户保存用户名、邮箱、可选单位、密码哈希、角色、下载审批与注册时间，不收集法定真实姓名。管理人员可查看审批所需账户资料。身份 cookie 用于登录；浏览器本地存储用于记住界面语言。页面不需要第三方追踪或远程字体。

密码不以明文保存；当前备份没有额外加密。数据由站点运维所在机器保存，并按备份配置复制；浏览器上传会把所选文件传送到当前访问的服务器。

Accounts store username, email, optional organization, password hash, role, download approval and registration time. Legal names are not requested. Administrators can inspect account information needed for approvals. A session cookie supports sign-in; browser local storage remembers the interface language. Pages require no third-party tracking or remote fonts.

Passwords are not stored in plaintext. Backups are not additionally encrypted by this application. Data resides on the operator’s machine and in its configured backups. Uploading sends the selected files to the server you are visiting.

上传者可按审核状态纠正自己的数据。超级管理员停用账户时保留贡献归属；删除实验先移入私有回收站，历次修改与备份也可能保留副本，当前没有自动清理周期。

若需更正身份信息、移除不当公开内容或申请彻底删除，请联系负责人说明记录编号与原因。具体处理需同时检查主记录、历史、回收站和备份，网页“删除”不等于立即清除全部副本。

Uploaders can correct their records as permitted by review status. Disabling an account preserves contribution identity. Deleted experiments move into private recovery storage, and history and backups may retain copies. There is no automatic retention deadline.

For identity corrections, inappropriate public content or permanent removal requests, contact the project lead with the record ID and reason. Handling must consider active records, history, recovery storage and backups; a web deletion does not immediately erase every copy.

数据疑问、账户问题、下载授权、许可和安全报告，请发送至下方联系邮箱。请描述相关记录编号、问题与可复现步骤，不要通过邮件发送密码或敏感原始数据。
