Yes, that is an obvious solution. The tradeoff is that you now don't get to say the relationship is hierarchical and get transitive inference, like you get with Category.

As others have said, there is a real need for other transitive relations that can give back the functionality we had with Category, but that was taken away from us in SMW because of its restricted use constraints.

Subject: Re: [Semediawiki-user] What to use instead of [[Category: x]] in SMW?

The obvious solution is to use semantic tags for this information - a relation or attribute like "Covers topic" could work nicely; you could then have as many of these as you wanted on a page.

If one restricts usage of Category in the SMW to get the right semantics of instance and subclass, then it cannot be used for other things that one uses Category for in MW to put things into 'buckets'.
 
Say there is a discussion about two different classes (chimpanzees and gorillas). In the MW, you would just put the page into the chimpanzee and gorilla categories, and it would mean that this page was about these two topics. But if I do that in SMW, it will think that this comparison page is an instance of both chimpanzee and gorilla, which is wrong.
 
I could create a parallel class hierarchy and create categories called PageAboutTopicChimpanzee and PageAboutTopicGorilla and this page would correctly be interpreted as an instance of these categories. I would also have to re-create each sub-category link too.
 
This would work, but means you have to manually keep the two hierarchies in synch, which is not ideal.
 
What is the recommended way to put pages into 'buckets' in SMW?
 
Is this discussed somewhere already?
 
I welcome your thoughts.
 
Thanks,
Michael
