This is probably a stupidity on my part, but I'm not sure where else to ask...
I'm using ubuntu 8.04 with the default install of tracker v0.6. I've indexed a large number of photos and have started tinkering with tracker's dbus interface and the tracker-extract command and noticed a couple things: 1. GetRegisteredTypes method in the org.freedesktop.Tracker.Metadata interface returns an empty list for the service_type 'Files' or 'Images'. Is this method not fully supported in the v0.6.6? (I notice the GetAll method available in trunk appears to be absent altogether in 0.6.6) 2. When I use tracker-extract to look at the metadata I see the following paltry list of key,item pairs (notably no date information!!) tracker-extract /path/to/file/p1050699.jpg image/jpeg Image:ISOSpeed=400; Image:CameraModel=DMC-FZ50; Image:WhiteBalance=Auto white balance; Image:ExposureProgram=Normal program; Image:FNumber=3.2; Image:Software=Ver.1.0; Image:Orientation=left - bottom; Image:Height=3648; Image:CameraMake=Panasonic; Image:Width=2736; Image:ExposureTime=0.083333333333333329; Image:MeteringMode=Pattern; Image:Flash=1; Image:FocalLength=9.6; exiftool on the same image exiftool /path/to/image/p1050699.jpg ExifTool Version Number : 7.00 File Name : p1050699.jpg Directory : /path/to/image File Size : 1386 kB File Modification Date/Time : 2008:04:23 00:52:14 File Type : JPEG MIME Type : image/jpeg Exif Byte Order : Little-endian (Intel) Make : Panasonic Camera Model Name : DMC-FZ50 X Resolution : 72 Y Resolution : 72 Resolution Unit : inches Software : Ver.1.0 Modify Date : 2007:12:31 19:59:44 Y Cb Cr Positioning : Co-sited Exposure Time : 1/13 F Number : 3.2 Exposure Program : Program AE ISO : 400 Exif Version : 0221 Date/Time Original : 2007:12:31 19:59:44 Create Date : 2007:12:31 19:59:44 Components Configuration : YCbCr Compressed Bits Per Pixel : 2 Exposure Compensation : 0 Max Aperture Value : 2.8 Metering Mode : Multi-segment Light Source : Unknown (0) Flash : Off Focal Length : 9.6mm Image Quality : Raw Firmware Version : 0.1.0.7 White Balance : Auto Focus Mode : Auto AF Mode : Spot Focusing Image Stabilization : On, Mode 1 Macro Mode : On Shooting Mode : Program Audio : No Data Dump : (Binary data 6152 bytes, use -b option to extract) Flash Bias : 0 Internal Serial Number : 9999:99:99 00:00 Panasonic Exif Version : 0210 Color Effect : Off Time Since Power On : 00:00:49.67 Burst Mode : Off Sequence Number : 0 Noise Reduction : Low Self Timer : Off Rotation : Rotate 270 CW Color Mode : Normal Optical Zoom Mode : Standard Conversion Lens : Off Travel Day : n/a WB Adjust AB : 0 WB Adjust GM : 0 Maker Note Version : 0100 Scene Mode : Off WB Red Level : 1532 WB Green Level : 1054 WB Blue Level : 2812 Baby Age : :00 Flashpix Version : 0100 Color Space : sRGB Exif Image Width : 2736 Exif Image Length : 3648 Sensing Method : One-chip color area File Source : Digital Camera Scene Type : Directly photographed Custom Rendered : Custom Exposure Mode : Auto Digital Zoom Ratio : 0 Focal Length In 35mm Format : 45mm Scene Capture Type : Standard Gain Control : High gain up Contrast : Low Saturation : Normal Sharpness : Soft Compression : JPEG (old-style) Orientation : Rotate 270 CW Thumbnail Offset : 7798 Thumbnail Length : 4688 Image Width : 2736 Image Height : 3648 Encoding Process : Baseline DCT, Huffman coding Bits Per Sample : 8 Color Components : 3 Y Cb Cr Sub Sampling : YCbCr4:4:0 (1 2) Aperture : 3.2 Blue Balance : 2.667932 Image Size : 2736x3648 Red Balance : 1.45351 Scale Factor To 35mm Equivalent : 4.7 Shutter Speed : 1/13 Thumbnail Image : (Binary data 4688 bytes, use -b option to extract) Circle Of Confusion : 0.006 mm Focal Length : 9.6mm (35mm equivalent: 45.0mm) Hyperfocal Distance : 4.49 m Light Value : 5.1 what am I missing?
