ImageIngesterPro is turning into ImageIngester+WorkflowSpeedup, with the Adobe workflow being the one I'm doing first, for two reasons: (1) It's the most popular, and (2) the XMP sidecar approach for metadata and Camera Raw settings is easy to get at (plain text files), documented, and has some 3rd party support (iView, anyway). For instance, iView has its own schema for XMP, and it shows up as a Bridge/Photoshop File Info panel.
Developers love it when outfits they have to interface with get together to adopt a common approach, because we get a lot of leverage from our efforts. Vendors can also easily justify rolling their own standard, but users are almost never served well by this. Case in point: all the raw formats out there, most of which are closed.
I'd be interested in providing raw settings for, say, Capture One, but I am so ignorant of it that I don't even know if it can import settings along with the raw image. This is research I'll have to do someday, or maybe some generous person will do it for me and tell me the answer.
I'll have to find out somehow how to get the info into Breeze Browser. ImageIngesterPro is limited to outputting only an image file and other well-documented files to sit alongside. No capability to go and write into some database or other app support file. It will be interesting to see how much assistance the Breeze people provide me, since I'm developing a competitor to Downloader Pro. Also, for Breeze, or any vendor, I have to weigh the development and supports costs against the probable number of users.
I didn't follow what you said about searching for keywords on import. Can you explain?
