Every link should have a relationship / predicate.

Fundamental to the Semantic Web. Personally, I feel sure it would make a huge difference to findability. (Though this is not yet generally accepted within the fedwiki community) In practical terms, this means supporting people looking for specific relationships between pages, including support or critique, for example. I’m thinking of the little known work of Andrew Ravenscroft and the dialogue game he called “InterLoc”, where all replies had to start with a framing.

The types of links would need to be very carefully selected, with maybe SKOS as a basis? But also needed to be included are logical and conversational relationships. In scientific terms, for example, we would want ‘gives evidence for’ and ‘is a counterexample’.

To enable there to be effectively no categories while allowing sub-categories, one of these semantic links would need to be something like “is_sub-category_of”.

A refinement of this – thinking of the subtleties of graph representations – maybe we could have both direct semantic links, and also links to the attributes or qualities of the relationship? For example, we could have a “rated by” semantic link between a page or an idea and a person; you could choose to go directly between the page and the person, or you could go to the details of the rating, like the numeric rating, some text explanation, and a date. Effectively this would be like an RDF blank node, but allowing direct linking across as well.

Implemented in several places, e.g. Semantic MediaWiki; … but it is not clear to me how well that fits the requirement.
