Hi Guys,
I am new to the project so forgive me if the answer is obvious...
I am working with latest svn bits and the
org.apache.commons.imaging.formats.tiff.taginfos.TagInfo class seems to
only
support the TagName column of Table 3 TIFF Rev. 6.0 Attribute Information
Used in Exif in the Exif spec <http://www.exif.org/Exif2-2.PDF>. I need
access to FieldName as it seems more suitable as a human-friendly
identifier
for the tag.
I think it would be ideal if TagInfo supports both TagName and FieldName.
What does the dev team think? If there are not many -1s then I will file
in
RFE in JIRA.
Thanks for your input.

Hi Farrukh
The TIFF6 specification Appendix A only has a "TagName", which is
similar to Exif 2.2's "FieldName". Other TIFF tag specifications (DNG,
TIFFPM6, RFC 2301) also only give a name and a description.
Maybe what we need is:
Use TagInfo's "name" field for the name taken verbatim from those
specs (eg. use "ImageWidth" instead of "Image Width")
Add a "description" field to TagInfo with a long description (eg.
"Image width, the number of columns in the image")
What do you think?
Hi Damjan,
+1 on your proposed solution for using TagInfo.name for the Exif 2.2's
"Field Name" and for adding a TagInfo.description for Exif 2.2's "Tag Name".
This is what I was thinking as well. That in conjunction with existing
TagInfo.tag (the numeric id) completes the identification, naming and
description of the tag and makes for a clean model.
What do dev team members <http://commons.apache.org/imaging/team-list.html>
think about this proposal?
As an aside, this matches very well with ebXML RegRep's Registry Information
Model which is what I am trying to map photo metadata to. My eventual goal
is to define a standard specification to manage image content and metadata
in an ebXML Registry and Repository.

Those dev teams members are no longer around, it's mostly just me :).
"description" is going to be difficult, as only EXIF provides it. But
I'll start doing the "name".
Hi Damjan,
Please see the patch I submitted for thread:
http://mail-archives.apache.org/mod_mbox/commons-dev/201207.mbox/browser
Above thread seems quite related to this one.
I think IPTC provides description too.
If a metadata format other than EXIF or IPTC (which are others btw?)
does not support description then we can simply return null for that.
BTW, ok if I start a JIRA issue (or should it be two?) to track both
threads' issues?
