CoExif is a fast cacheable JSON REST File Metadata Server, which supports nearly any file format. It uses one of the best metadata management tools outhere: Exiftool. Internally, CoExif uses a pool of long running ExifTool processes.
#Getting Started
Exiftool. must be downloaded. One of these builds must be downloaded also:
Server must be started providing a path to Exiftool executable. Like this:
co_exif -root "/home/mik/" -port 9200 -auth-name="admin" -auth-pass="admin" -exif-path="./exif_tool/exiftool"Now, the server can be queried. This part of url:
127.0.0.1:9200/<this_part><filters>is FS path without -root param in server settings.
curl -u admin:admin 127.0.0.1:9200/2.jpg

}
]
}It is good to have been able to select specific tags:
curl -u admin:admin "http://127.0.0.1:9999/home/mik/?tags=FileAccessDate&tags=FileName"
{
"Items": [
{
"FileAccessDate": "2015:08:02 20:10:40+03:00",
"FileName": "output.avi",
"SourceFile": "/home/mik/output.avi"
},
{
"FileAccessDate": "2015:11:02 15:24:44+03:00",
"FileName": "DSC_0158.NEF",
"SourceFile": "/home/mik/DSC_0158.NEF"
},
]
} Post will replace metadata in a file with specified fields. Please refer to Exiftool TagNames to know what type of tags can be rewritten.
Example:
