== About ==
Working with image files (photos, etc.) often requires storing information about the files. There are already a number of storage formats to achieve this. There are also a number of packages working with these formats. The intention of this page is to document which programs work with each other. Please extend it if you have knowledge about a specific program.

== Formats ==

=== XMP ===
You can find details about this format at [[WikiPedia:Extensible_Metadata_Platform|Wikipedia's page on XMP]].
This format is embedded in a number of image formats. For image formats that do not support embedding the metadata, it can be stored in a file with extension "xmp" next to the image file.

== Packages ==

=== geeqie ===
Package info: DebianPkg:geeqie
<<BR>>
Supports two different internal plaintext formats in ~/.geeqie/metadata (old) and ~/.local/share/geeqie/metadata (new).<<BR>>
Supports reading and writing XMP.<<BR>>
Supports saving metadata in a .metadata directory next to the images.<<BR>>
When searching for keywords geeqie needs to traverse the filesystem tree, so searching can be slow.
