Hi, I've compiled a list of all attributes that I think we should define globally, such that applications can use them as needed. I've only covered user visible attributes so far. For now, I've opted for lower-case prefixes, and names, but this is, of course, open for discussion. Other options would be "MEDIA:duration", "MEDIA:Duration", "Media:Duration", etc. If anyone thinks there is some attribute missing, please shout. --------------------------8<-------------------------- Tracker visible attributes */* META:comment META:keywords (i) comma separated list META:location (i) comma separated list META:rating int32 (i) from 0 to 10 audio/*, image/*, video/*, text/*, application/(x-)ogg, application/x- asf media:duration format h:mm:ss[.f] or m:ss[.f] media:genre (i) comma separated list of genres media:language (i) maybe only language tags that are expanded for display? media:producer media:thumbnail raw (PNG | JPEG) media:year int32 (i) audio/* audio:album (i) audio:artist (i) audio:bitrate audio:title (i) audio:track int32 image/* image:aperture format "f/<aperture>" image:focal_length example: "28mm" image:resolution format "<width>x<height>" image:iso (i) example: "ISO 200" image:exposure_time example: "1/60s" video/* video:bitrate video:director (i) comma separated list video:writer (i) comma separated list video:ratio format "x:y" video:resolution -- (i) indexed attribute no type implies string type --------------------------8<-------------------------- Comments welcome. If there are no objections, I will add these types to the image, and let MediaPlayer add those that it can add (and show them in the info window, too). Bye, Axel.
