Here's a variation of cubic's script with a couple bells and whistles:
supports selections of multiple Finder items, adds a "Finder" tag,
inserts a comment with the creation date (not strictly necessary since
Yojimbo tracks import and creation dates, but change it to whatever
you like).
property YojimboTags : {"Finder"}
on run {input, parameters}
tell application "Yojimbo"
repeat with i in input
try
set dateString to "Saved path from Finder on " & (current date) as
string
set fileBookmark to make new bookmark item with properties {name:
(name of (info for i)), location:"file://" & (POSIX path of i),
comments:dateString}
add tags YojimboTags to fileBookmark
on error errMsg
display alert errMsg
end try
end repeat
end tell
return input
end run
Thanks to both of you for the inspiration!
