People might be interested to know that semantic web ideas have been more successful in some niches than others. Computational biology for example makes extensive use of "ontologies" which are domain specific DAGs that do exactly what Abstract Wikipedia is attempting. Much of the analysis of organism's genomes and related sequences relies on these ontologies to automatically annotate the results so that meaningfull relationships can be discovered. There are of course HUGE issues with the ontologies. They are not sexy projects so they are often underfunded and under resourced - even though the entirety of bioinformatics uses them! The ontologies are incomplete and sometimes their information is years behind the current research. For the curious, the Gene Ontology is the golden child of biology ontologies.
