+# 统一可交换成就标准 v1.1
+
+> Uniformed Interchangeable Achievement Format standard (UIAF)
+## 前言
+
+由于原神的第三方成就识别、导出、记录软件越来越多，在有了 UIGF 的经验后，
+我们

+* [babalae/genshin achievement toy](https://github.com/babalae/genshin-achievement-toy)
+* [DGP Studio/Snap.Genshin](https://github.com/DGP-Studio/Snap.Genshin)

+* [YuehaiTeam/cocogoat](https://github.com/YuehaiTeam/cocogoat)
+
+（上述名称以字典顺序排序，不代表其他任何意义）  
+在此一起，制定了此项标准，旨在加强各个原神相关的App间的数据可交换性。
+
+## 注意事项
+
+### 时间
+
+本标准的所有时间格式均以 `UTC+8` 时区为基准

+
+### `info`
+
+可以包含我们认可的以下字段
+
+|字段名|值|说明|
+|-|-|-|
+|`export_timestamp`|导出UNIX时间戳||
+|`export_app_version`|导出此份记录的App版本号||
+|`uiaf_version`|所应用的 `UIAF` 的版本,包含此字段以防 `UIAF` 出现中断性变更时，App无法处理||
+
+#### `uiaf_version`
+
+合法值
+
+|值|说明|向下兼容的最低版本|
+|-|-|-|
+|`v1.0`|首个正式版本|v1.0|
+|`v1.1`|在 `achievement` 中引入了 `status` 字段，指示成就的完成情况|v1.1|
+
+#### `export_app`
+
+未实现导出支持的以 `-` 代替
+
+|导出 App|`export_app` 的值|
+|-|-|
+|Empty|Empty|
+
+### `achievement`
+
+#### `id`
+
+原神的成就在游戏内部带有Id，对于扫描类导出软件，在取得成就的外在表现形式（如：呈现文本）后，便可对应到内部的Id
+
+> 导入/导出软件应自行负责Id与呈现文本间的转换  
+> 成就的信息可以从 [Dimbreath/GenshinData](https://github.com/Dimbreath/GenshinData) 库中获取
+#### `timestamp`
+
+* 对于识别成功的值，直接将时间转换为对应的UNIX 时间戳（秒）
+
+* 对于识别失败的值，直接将时间设置为 `9999-12-31 23:59:59`（253402271999（秒））
+
+#### `current`
+
+* 对于识别成功的值，如 30/40 `current` 的值应设置为30
+
+  > 因为始终可以从原神的数据中找到目标达成值
+* 对于识别失败的值，请将该字段的值设为 `0`
