Okay, about this splice/category thing with the Dmoz rdf file. Here is how you do it:
1. Either use wget or lwp to download the file to your server. Will require approximately 200mb's of space.
2. Download it to your computer. I'm on a cable modem and it takes me about 10 minutes or less to download.
3. Unzip it using your favorite zip utility.
4. Go to
www.vedit.com and download the trial version of the vedit program.
5. Install vedit on your computer and upload the content.rdf file. You will be able to load and edit the entire rdf file with vedit.
6. If you want a particular section, do a search for, let's say Top/Arts. Go to the file menu and set a line marker. Once you have that done, you can either page down or search for the next category, such as Top/Business, and the line marker will highlight everything from the beginning of your search to the end. Go to the file menu and save block as whateveryouwantittobe.rdf.
7. Upload this small rdf file to your server and import using Links. I can break down the entire content.rdf file into about 20 different categories in about an hour using this program.
NOTE: If you try to start a search from Top/Arts to the bottom of the file i.e. Top/World, the program will lock up. Go from Top/(category) to Top/(category) and it won't lock up on you or use the side navigation slider bar thingy in small increments. This is not a fault of the program, but a result of the sheer size of the file.
I regularly use this method and it is very easy to do once you get use to using the program and the search capabilities of the program. I currently have the current rdf file that I am parsing into links, and I took out the Top/Adult section in about 5 minutes.
Vedit, get it, use it, enjoy...
