Has anyone else had the experience of IPTC metadata, added to an image file using PhotoShop CS2, CS3 or CS4, not importing to EMu Multimedia? We are trying to understand why the specific version of PhotoShop installed on some of our workstations appears to save IPTC metdata so that it is imported to EMu when the image is uploaded to EMu, while the version installed on other workstations saves IPTC metadata with the image file but for some reason the metadata is not imported along with the image when it is uploaded into EMu. We're wondering if there's some setting buried in either PhotoShop or EMu that we need to change. Thanks for any suggestions.

Hi Karen,
We had similar problems when our photographers first updated to CS3. I think what we came up with was that it isnt a problem with the EMu interaction, it is a problem with Photoshop. I think we're over it after a few Photoshop upgrades...
With regard to EMU, we did discover that certain characters in the IPTC data may cause EMu to skip information. I will have to look back to our help desk messages to get the details of that. I'll post back here if I find more info for you.
cheers

Also, see what happens on the ones with missing info when you run a Multimedia - Update Resource on the record.

Karen, here are some ideas for you, based on our own experience here...
(1) Bulk Load Tool
First of all... are you using a KE bulk load tool to load your images? We found that the colon character was sometimes being used in the metadata fields and causing the loading script to skip.... see extract here...
" We have discovered that characters such as : (colons) in the description
> field of the image file header are causing the data to split during the
> bulk load process. Eg Exhibition name "Contemporary Australian craft: a
> Japanese view" splits at the colon and places "a Japanese view" in the
> Compression field and bounces all subsequent metadata along to the next
> field. Because Compression, Make, Model etc are auto complete fields it
> is not possible to edit these fields and the records will not save.
>
> Can we change the metadata harvesting of the Photoshop description field
> so that it does not jump on characters?
2 fixes that would be straightforward to implement:
1 I call the utility for each metadata item separately and process them
independently. This will mean you can have any symbols in the metadata.
Unfortunately this will cause a big slowdown in the speed of loading though,
particularly for large tiff images (the call to get the metadata is currently
one of the slowest parts of the load process, calling this utility which
currently runs once per image up to 30 times per image would be a significant
cost)
2 we change the character used (no speed penalty however if that character
appears in the data then you will hit same snag as with the colon).
Option 2 to me seems better case (because of speed) but means we need to choose
a better separator symbol. 3 that I think may be OK are the tilde(~), the
caret (^) and perhaps the pipe(|). If you think option 2 OK can you let me
know what symbol is least likely to appear in your metadata? "
-We ended up going with the ~tilde as our separator symbol.
(2) Photoshop Issues
I also vaguely remember that the problem was with the CS3 export of the XMP file (the file that contains the IPTC
data)... it just didn't work sometimes... a bit of searching revealed that lots of people around the world were having similar issues with Photoshop.
Here is an extract from a website that I found while trying to solve the problem...
"In 2004 IPTC Core was released. It offers many more useful fields aimed at areas such as rights management and specific contact details. Based on XMP it allows users to make custom IPTC fields and share them as templates in other XMP compliant software. Currently only Adobe fully supports XMP. Like anything new there are teething problems.
Most application vendors that have supported IPTC have done so using the older specifications that stores data in the Information Resource Block (IRB) based on Information Interchange Model (IIM). Bringing software up to speed with XMP will take time.
Issues have arisen with the change to XMP. When one application has written IPTC using IRB into a file and a second program
updates that data using XMP it's possible that two sets of metadata now exist in the file, IRB and XMP..... Until all mainstream applications use XMP it may be best to stick to either IRB and IIM, or XMP and IPTC Core. Essentially this means only caption in Adobe products, or never caption in Adobe products.
If you caption before Photoshop it will honor legacy IPTC metadata and copy it to any derivative image. Alternatively discipline yourself to only use Adobe Bridge or Photoshop for writing and appending IPTC.
Like any new standard time will eventually sort this out. When applications can read and write IPTC together it is often
referred to as roundtrip metadata. Asset management software Extensis Portfolio 8, iView MediaPro 3, and MediaDex can both read and write XMP, but currently only Portfolio can work with IPTC Core custom panels."
========================================================
I hope something here helps you solve the problem!
cheers

Thanks for sharing all this information, Karen. We are using Emu's import tool to batch upload images to the Multimedia module. Your experience supports our suspicion that CS3 is likely at the root of our problems. We have one workstation with CS3 (others have either CS2 or CS4 -- don't get me started on the topic of version control!), and images that had IPTC metadata added on that workstation seem to be the images that are giving us trouble. We'll do a little more testing, but it looks as if simply not using CS3 will solve this problem.
Thanks again for your quick and thorough reply, Karen.

No worries Karen,
If all your photographers and other media editors are entering IPTC data uniformly, it shouldn't be too difficult to pinpoint the cause!
(ps. the Bulk Load tool I mentioned is a special program developed for us by KE... the standard Import Tool doesn't give us any problems in this regard, that I know of).
cheers
