Thread:Help talk:Repairing SMW's data/My property list is mainly empty - what happened and how do I fix it?/reply (13)

That certainly wouldn't work!

Looking at the documentation, it suggested that the standard, with no option, or a -v if you want to see how it is going, rebuilds the properties and so forth by looking at each page in turn from pageID 0000 on to 4000 or however many there are.

The -cpt, on the other hand, seem to rebuild the tables from properties, categories and other indices that it gets from elsewhere, an existing table or log, presumably - because it is much quicker and only looks at the ~500 items.

So the logic, to me, was to make sure the tables for the indices were in place with the -cpt option. Then get it to go through each page adding links to the indices.

The logic behind running it more than once was that there might be links that are not apparent the first time, concealed by parse expressions or similar that it might pickup on another pass.

I was hoping that one of the authors of the script could enlighten me on whether I've misunderstood.
