I am a new user of Gallery Server Pro (and love it). I use Adobe Lightroom for my photo collection and fill the metadata fields as professional organisations are doing; IPTC and extra XMP fields (although lightroom puts IPTC data also in XMP). I enter the title in the IPTC headline field and leave the EXIF/windows title field empty. According to documentation found on the web and several discussion forums the title field is used for a reference code, the original filename etc and not to be used as a title/headline for a photo. It is confusing as they used the fieldname "Title".

Some document/site references:
Discussion on adobe lightroom forum
pdf doc IPTC standard v1.1 (search for title and headline and read the explanation)
pdf document IPTC XMP core scheme (again search for title and headline)
Guide to Photo Metadata Fields

When I export my photos from Lightroom and synchronise them with Gallery Server Pro the title below the thumbnails/images contain the filename instead of the IPTC headline field as the "Title" field is used instead of the IPTC headline field.

Searching this forum I saw some discussions regarding the functionality of the microsoft component to read metadata. So I do not now if it is possible to read the IPTC headline field (but as it is stored in XMP it should be).

I could modify the GSP source, but that doesn't have my preference. So for time being only trick I can think of is making use of exiftool to copy the IPTC headline field to the title field. But this is also not a sustainable option.

So best option would be to have an GSP preference which let the user define if the "title"or the "IPTC headline" field needs to be used for the photo title. Or even beter which one has preference on the other, so if the first one is empty the second one is used (if it contains data of course).

Thanks for the links and the suggestion. I am open to the idea, and it would be helpful if you could provide a sample image that contains the metadata in the configuration you are using. Include a note about which text you want to be used as the title in GSP. Email it to roger*at*techinfosystems*dot*com.

Roger,

Some months ago, but you were bussy developing the DNN module and I testing it and giving feedback. As I started to use the DNN module in practice I stumbled again over this issue.

On 9-May I sent you an email with the requested example picture. For me and probably other users the ideal situation would be a settings screen in which can be selected what IPTC or EXIF field ends up in the Thumbnail and/or compressed image title & fields in EXIF info dialog of GSP.

Do you have any thoughts about this and what possible timeline would be? If it wil take some time I have to look for an intermediate solution, but this does not have my preference as I managed to upload to my website straight away and controllable from lightroom via the plugin FTP Publisher.

I am happy to give more info etc. if required

Regards,
Jan-Willem

I still have your email and it is flagged for follow-up, but I have not been able to do so yet. I took a quick look now and am having trouble figuring out what the text is for the "IPTC headline" and "IPTC caption", since nothing is labeled like that when I look at the picture in Win Explorer. Can you follow up that email with this info - in other words - describe the exact text you are hoping to use for the title.

Win explorer does not show much. I have a freeware gui somewhere which is build on top of exiftool. This makes it easy for you to see and modify these fields in an image to play around. I will have a look for it today/tomorrow.

Also another "wild" idea: it can also be solved by implementing a template function for this dialog which accepts HTML code with tokens for available fields. Each user can then modify the exif dialog if wanted. By default template content is then the same as current screen.

I like your idea. That is just the kind of thing I want to do as I restructure the metadata functionality for the next major release (which includes tagging).

Found it quicker then thought:

1. Download exiftool (the windows executable is enough):
exiftool

2. Download ExiftoolGUI:
ExiftoolGUI

3. Extract both files and copy the exiftool executable into the exiftoolgui folder while renaming it to exiftool.exe

4. save my example photo to harddrive

5. start exiftoolgui and point to the example image


At top right you can click on the info categories (EXIF, IPT, XMP). The button below a category makes it possible to modify this info.

Under IPTC you find the field "headline" with "Afrikaanse olifant" (African Elephant). The caption field is named here "Caption abstract" in this case its filled with same info as in headline.

Regards,
Jan-Willem

Actually this ain't such a good idea at all. I even had to turn the advanced metadata extraction off, because deriving the caption off the filename is the most reasonable way to have the gallery sorted chronologically. Since my Sony Alpha A100 fills the Description field with "SONY DSC" string, all photos are then named the same. The only way to change the metadata is actually change it in Lightroom manually one by one. I actually don't want to be forced to do that (that's why I turned the advanced metadata extraction off). This suggestion, if implemented, would, I suspect, force the user to take care about the metadata when processing photos. However there are users, who only need metadata to know the basic exposure values, not to sort the photos. Chronological sorting is mostly sufficient. So, please, Roger, if you implement this, make it an option, not a default (nor only) behavior. Thanks a lot.

Vlasta - Don't worry, the original behavior will be available as an option, regardless of how this is modified.

Jan-Willem - Thanks for the info about the ExifTool. I am still unclear what you want. I opened the photo you sent me last May and removed all EXIF data, then imported it into GSP. By default the text "Afrikaanse olifant" was used for the title, so .NET is clearly getting it from the IPTC or XMP sections. But I thought that is what you were asking for, so I am confused.

How about this: Please send me an image that, when imported into GSP, yields the "undesirable" behavior (and tell me what that undesirable behavior is). Then describe what you *want* to happen.

ok, will have a look into it tomorrow and come back with a clear explanation. I already use a plugin in lightroom to copy IPTC headline to the title field, but is another action in workflow which should not be required.

I will make image which is using the title field method (which GSP uses), one with IPTC headline and one with both. Will use the fieldnam as content so its easier for you to see what is happening.

Roger,

Compiling document with info from research I did today & created example photos. Are you using a standard windows method? Because I see the same issue with the properties dialog in windows explorer.

I am using .NET to extract the properties, and it abstracts the underlying EXIF/XMP/IPTC implementation. Specifically, I access the desired property through one of the property tags defined by Microsoft.

If this becomes an issue, I am sure there is a way to get around it by using a bare-metal approach, but that may not be practical for a number of reasons.

Thanks. I printed it out and read it - it is very informative. I fear we may have some limitations in the .NET framework that won't make some of your requests possible (or at least time-effective), but I will definitely explore and consider them.

At the moment I am working on 2.4.6, which will have a way to select which metadata category to use for the caption (e.g. title, camera model, etc). It will also have an admin setting where you can specify the order of the metadata and enable/disable the visibility of individual items. This will achieve at least some of your templating request.
