Provide example source code to work with iFDOs (other than MarIQT)
E.g. Jen Durden wrote this in R to add UUIDs to images:
`folder.of.images<-"/Volumes/folder" # filepath of folder containing images df<-data.frame(list.files(folder.of.images)) # create data frame with list of images colnames(df)<-"image-filename"
df$imageuuid<-NA # initialize column to store UUIDs
library(exifr)
for (i in 1:length(df$image-filename)){
df$imageuuid[i]<-system("uuidgen", intern=T) # generate UUID and write to file
exiftool_call(args=paste("-imageuniqueid=",df$imageuuid[i],sep=''),
fname=paste(folder.of.images,"/",df$image-filename
[i],".jpg",sep="")) # write UUID to image header
}
test whether UUID was written to image
read_exif(paste(folder.of.images,"/",df$image-filename
[i],".jpg",sep=""),tags="ImageUniqueID")`
