Semantic JavaScript

Javascript is semantic, just like HTML, every language has its own semantics.

HTML is used to describe the contents of a web page, and Javascript could be used to describe these same contents. If we consider the contents as a description (as in HTML) then we only need JSON, converting from HTML to JSON and backwards would simply be a syntactic translation, instead of the tag "head" we would use the attribute "head" in some Javascript object.

But why would we do that?

HTML works quite fine for what it does, if there is any movement in this direction I think the first steps will be Javascript templates to generate HTML out from JSON, as any decent server side language does already.

I'm sorry this doesn't address the semantic web topics.

Now, if we consider the languages used for knowledge representation in the semantic web, as RDF, and how it can be expressed in XML, N3, Turtle or other notations it's easy to see that we can easily do something similar with JSON. And maybe it would be convenient and save some time and effort from parsing if we are going to reason (infer new triples) using some Javascript engine.

Is that interesting?

I don't know. Maybe you or someone else can come up with an interesting use case. My perception is that this kind of agents that use the knowledge available to reason over it tend to be developed as services in the cloud, and they may be free but retain the code and the economic profit possibilities. Javascript is gaining strength in the server side with Node.js, but I cannot tell which language may become the most widely used in the cloud or how long or how strong may be the predominance of the cloud as the business model for semantic web applications (if that ever happens).

tl;dr

In short, technological progress will be where money is or where crazy people are making some progress regardless of the money. Where is the money? I wish I knew, please tell us if you find out. Until then, I will side the crazy people :)
