哪个 EXIF 标签存储照片的关键字/标签? [英] Which EXIF tag to store keyword/tag for a photo?

问题描述

我正在开发一个可以读/写 EXIF 标签的照片库.我会将照片标题放在 EXIF 标记 DocumentName 中，将描述放在 EXIF 标记 ImageDescription 中.我还计划使用地理标签.但是照片标签/类别呢?我想在我的系统中存储一个以空格分隔的标签字符串.是否有任何 EXIF 标签通常用于此类信息?我可以自己编写(即 PhotoTags)，但我想除了在我的系统内部(无论如何，这些信息都存储在数据库中)之外，这并没有任何用处.

I am developing a photo gallery which will read/write EXIF tags. I will put photo title in the EXIF tag DocumentName and description in EXIF tag ImageDescription. I also plan to use the geo-tags. But what about photo tags/categories? I want to store a space-separated string of the tags a photo is tagged with in my system. Is there any EXIF tag that is normally used for this type of information? I could write my own (i.e. PhotoTags) but I guess that is not really of any use except for internally in my system (where this information is stored in a database anyway).

推荐答案

我想会想看看 用于存储关于图片(例如关键字/标签、标题、描述等).

I think that will want to look into IPTC and/or XMP (not entirely clear over their relation) for storing metadata about images (such as keywords/tags, title, description and so on).
