Hi Tom: Amen. Thank you for writing this. I completely agree. RDFa has some great use cases but (like any technology) has its limitations. Let's not oversell it. We seem to agree on the observation, but not on the conclusion. What I want and suggest is using RDFa also for exchanging a bit

Bernhard, Yes, I understand that this is how rdfs:domain and rdfs:range are interpreted. I agree that the knowledge addition of RDFS and OWL is a great strength. I would rephrase your interpretation to: you can use foaf:holdsAccount. if something has a foaf:holdsAccount property then you MUST

All, Thanks for an interesting discussion. It is interesting how many visual styles different people can come up with. Is there a place that gathers these up for comparison? I made a twine at http://www.twine.com/twine/12df6wvd7-1f0/owl-the-web-ontology-language-visualization. It includes the

Hi Yihong: I am a big fan of Codd's one fact in one place credo. However, in this particular case, that principle is violated anyway, since the literal values are often duplicated for presentation and meta-data prupolses anyway (think of 2009-06-29 vs. June 29, 2009). Second, for dynamic Web

Hi Toby, Yes...of course...you are right. :) I would say too, that reification is even more long-winded than the example you have given! You don't have the actual statement the sky is blue in your mark-up, so you need even more RDFa. (You only have the statement Mark says 'the sky is blue'.)
