I work with a lot of personal heritage photos that have digital and paper counterparts that I want to keep track of, so I have some keyword groups that others would probably not agree with, but that work for my particular situation.
I'm very interested in how you do that, that is an area that is expanding in my own image cataloging.
One of the things I spent some time today doing is looking at how I've searched for images lately. Knowing what questions I'll be asking is an important part of deciding on how to catalog them.
Here are some typical searches I've had to perform in the last few months.
Find pictures of AI sired lambs for NAGP to use in articles describing our non-surgical AI procedure.
Find pictures of the most recent version of the AI procedure showing me doing the AI I should be able to search for me, and AI and find them but again, not everything is keyworded yet.
Find pictures of the AV prep and semen collection procedure for a newsletter article.
Find pictures of guard dogs with newborn lambs for a newsletter article for the sheep association
Find pictures of the contents of my lambing bag for a blog post
Find the FLIR pictures with temperatures of the vulva and anus of all the ewes that lambed to AI for the paper on the use of FLIR to gauge the proper time to inseminate the ewes. None of the FLIR pictures are even in Lightroom yet so I've been using LambTracker a search for ewes that lambed to AI, then search to see when they were bred, then go back to the notes on exactly what time they were bred then locate the FLIR pictures from that group and cross reference with the EID ear tag scans of the inseminations to put the correct picture with the correct sheep.
Find pictures of the necropsy on sheep that died from clostridia infection
Find my best pictures of Mt. Lamborn on such and such a date for as many years as I have, I really wanted a fuzzy search so that If I was within a week of the same date in a different year I could find it.
Locate pictures of Desert Weyr Caridwen with her triplets. I went to my LambTracker database, did a search for lambing records for Caridwen, and wrote down the birthdates of her 2 sets of triplets then looked on that date and few days after that date in the LR catalog for photos. Ideally those pictures should have been keyworded with the sheep name and with the lamb names but they weren't. I did find them but it took a lot longer than I wanted it to.
Locate pictures of a specific petroglyph panel/location taken over the years showing the changes. I have some that are of the same panel taken in various years that dramatically document the destruction of the petroglyphs over time. These have been nearly impossible to find with a smart collection, I have some of them keyworded with either petroglyph or pictograph but that isn't sufficient and for security reasons even if I have the GPS coordinates they are not entered in the metadata as I don't want to share them. Still working on this one.
Find all lamb pictures of Desert Weyr Yoda and of Desert Weyr Yoda 2 for a scrapbook page on the 2 lambs. Again the pictures should have been keyworded with the sheep names but they aren't so I'm using LambTracker to find dates when they were born and then looking by date to find the pictures.
Find the pictures I took of the White Castle in Wales
Find the pictures of the riveted chainmail details from the Met's armor collection and send to a friend who is working with a smith to make some test pieces of historically accurate chainmail.
See if I have any herring cozy pictures like the ones from a Ravelry thread on a double thumbed mitten common in the Scandinavian countries. I thought I'd found and taken a picture of one at a local historical society museum. Haven't found that image at all yet, still looking.
So a rather eclectic set of searches and that's just in the last month or so.
Clearly I look for sheep by name more often than people.
I also tend to look for sets of pictures related to specific times or activities so that's another major class of keywords I need to include. Locations are easy to add if they don't fit into the country city location fields already.
