Michael,

The challenges I see are the same challenges that come with the traditional
PageRank model.

First, spam. Whatever model you use has to have balances in place that
measure trust and credibility using multiple signals or you potentially
risk people trying to manipulate your ranking system. I'm assuming for a
hobby or even an academic project, this is less of a concern, but anything
where there's the potential for revenue or traffic is subject to
manipulation.

Second, context. Along the lines of what Nathan was saying, what resources
count as important are somewhat relational to what questions people are
asking. I'd also expect that they're relational to particular biases that
the searcher has. FOAF and the social graph provide some answers, but I
haven't seen a lot of applications use it effectively outside of walled,
proprietary silos.

Third, which you pointed out, computing capabilities. It's hard enough
indexing standard web resources without having to follow the large number
of links that would come when you factored in triples.
