Hi all, with a slightly different take on, may I suggest treating the "application, UI, services, etc. layer" as something independent of the rest of the cake? IMHO, any layer can be applied or interfaced per-se, or *an* application may possibly exist at any step in the layer cake... Maybe one way how this could be expressed is to add an orthogonal dimension rather than a layer, and then we can say e.g. things like: "application purely at the layer of URIs/URLs = e.g. web site.... (most of 'web 1.0'?)" "application at XML level subsumes URI level = e.g. EDI or suchlike" "app at RDF level = tagging, RSS in RDF........ (some 'web 2.0' stuff?)" etc. etc. What this might enable us to do is to attempt some fuzzy boundaries on the application axis where SemWeb benefits may become more obvious (e.g. at the level of min RDF-S + SPARQL); at the same time this is a more inclusive view that does not exclude those people/companies for whom the XML box might be sufficient to consider their app "semantic"... So in principle, I would see the data provision layer as without any bells and whistles, anything from the cake above it brings the app closer and closer to the full-scale potential of SemWeb. e.g SQL access is outside of the cake, so no chance there, but XML endpoint is a tiny step closer to semantics, RDF endpoint even closer, etc. IMHO, such a more inclusive view may be easier to reach out with, than anything implying many layers that are too ill-defined for many stakeholders... anyway, just a thought - hopefully not too philosophical... :-) Regards, M. -- Martin Dzbor -- KMi (The Open University, UK) http://kmi.open.ac.uk http://www.neon-project.org ----- Original Message ----- From: "Wilson, MD (Michael)" Sent: 30 November 2006 17:46 Subject: RE: Semantic Web Layer Cake Update Suggestion Jeff The main problem with that diagram is the User Interface & Applications layer at the top which suggests that applications can only be built on top of the Trust layer, and not on top of each layer.

Although I don't personally feel that the XML serialization of RDF is such a big market issue, real or perceived, the picture there seems to address the concern quite nicely.

I have also added a Data Provider / Data Source layer since the URI/IRIs are "Resource Identifiers" for Data which has to come from somewhere :-) -- Regards, Kingsley Idehen Weblog: http://www.openlinksw.com/blog/~kidehen President & CEO OpenLink Software Web: http://www.openlinksw.com
