First, let me thank you for your amazingly rapid response!
It sounds like I might be able to make XML work for me although I’m not familiar with the structure. I haven’t done much programming since my FORTRAN and BASIC programming back in the days of Lisa’s, Apple IIs, Commodor 64s, etc. (yes I am that ancient - comma separated ascii was state of the art stuff back then).
I’m a consultant and have a massive engineering library. A lot of the stuff is really valuable to me - hand written notes from experts on various engineering problems, etc. It takes up a lot of space because it’s a PDF graphic file. I can’t be scanned with handwriting recognition software because it’s mostly equations and stuff. So the solution is to add descriptive titles and key words in metadata.
Even though these documents are irreplaceable, I rarely need them. So I want to be able to archive them to off-line storage for safety and space reasons. But I would like to have a database (titles, tags, comments, etc.) that I can take with me on my laptop (or perhaps even the iphone using Handbase ) and look up reference material when a problem comes up. A CSV file could be easily imported into Handbase, Bento, Excel, etc.
