A while ago, I had to transfer my bookmark collections from FURL to Diigo. While the process was automatic, my tags turned into a mess. I had developed a clever way of organizing my tags in FURL. At the time, I thought it was quite clever. It worked very well for me and I even wrote a little paper about it (Learning from Doing: Social Bookmarking).
I should write a Part II to explain why it turned out to be very dumb. I certainly didn't anticipate having to transfer the bookmarks to another service and what that would mean in terms of "portability." Here's a quick example. I used tags like these:
"ICT -- Access"
"ICT -- Education"
"ICT -- eGov"
In the transfer, these tags ended up split into three parts: "ICT", "--" and "Access". I had 800+ meaningless "--" tags. It will take a while to clean up the mess. There's probably a bigger lesson to be learned here but I haven't figured it out yet.
By the time I'm done with the clean up and I've learned to use all of Diigo's capabilities, it will be time to transfer to the next best thing!
Why bother cleaning up? I would like to be able to link the relevant collections (KM tags in particular), to my Learning Log business novel.
I now have a "didactic fiction" bookmark list on Diigo.
