Advanced Metadata (Exif, GPS, IPTC, etc.)
« on: February 25, 2008, 01:26:30 am »

(Devs are already informed earlier)
Currently I'm researching Jpeg Metadata for a complete new metadata reader.
Because Exifer (and the other PHP lib PHP JPEG Metadata Toolkit) are old and unmaintained.

Due to that i discovered that Exifer, and even PHP Exif extension, have serious issues with array data.

For example a newer Canon model (EOS/1D maybe?) which has several MakerNote fields that contain a large array with integers.
For example the ColorBalance1 tag contains 692 integers in a EOS 40D MakerNote.
In total the EOS 40D contains 16 arrays from 3 up till 692 entries inside an array!

Or what about the latest and greatest Sony A700?

So you could experience Exifer crashing on that.

However, i wonder how useful some metadata extraction is for people.
Therefore here's a list of options and you decide "which" features you request to be implemented.

Note:
1) Marked as bold is already getting implemented.
2) Strike through will be abandoned


Althought IPTC is phasing out, you might still use it?

Professional photographers love IPTC, but it has got a serious drawback: lacking unicode support.

Time has gone. Is there any development about this?

I live in Finland, and we have these ä and ö letters. I`ve been facing a lot of problems with those letters when exporting from Lightroom. With several gallery softwares.

BUT, same letters are ok in Facebook? How they have solved it.

I guess they convert it to unicode if it isn't already unicode, but that's just an assumption.
