Supported Metadata Tags
Hi,
I was wondering if Tika supports:
IPTC (image)
XMP (image/video) -- yes, AFAICT
EXIF (image) -- yes, AFAICT
DCMI (image)
PLUS (image)
RIFF (video)
ID3 (audio) -- yes, AFAICT
Anyone else know about the other formats?
Thanks,
Grant

There is support for this in Staffan Olsson's git fork (see TIKA-482). I'm
hoping Staffan will submit an updated patch of this shortly which we'll
then be able to apply :)

We can generate XMP metadata, but not read it. If memory serves, we're
waiting on some bug fixes in pdfbox before we can use some of their code
for reading, but it's not my bug so I could be wrong!

Yes
> DCMI (image)
As in dublin core? If so, we do map some image metadata onto dublin core
entries
> PLUS (image)
I've not come across this one before, so I suspect we don't support it
> RIFF (video)
No support yet, but it's one that there is some interest in. If you could
upload some short video files and audio files to JIRA, along with the
details of the metadata in them, it might be enough to prod someone into
adding at least basic support :)
> ID3 (audio) -- yes, AFAICT
Support for ID3 v1, v2.2, v2.3 and v2.4 are all in, yes

Hey Grant,
In the latest version of Tika 0.8 trunk, I added a utility to print the
supported metadata models and associated tags that are part of Tika.
If you¹ve built a fresh copy of tika-app, you can do:
java jar tika-app-0.8-SNAPSHOT.jar --list-met-models
That will print you out a list of:
<model name>
<met key 1>
<met key 2>
<model name 2>
<met key 1>
...
On your list below, Tika supports DCMI if you are talking about the Dublin
Core Metadata Initiative (DCMI). As for the others, others can speak up...
Cheers,
Chris
