How is Wolfram Language different than regular Mathematica?

Is there the full Wolfram Language in Mathematica?

• Today I read the http://blog.wolfram.com/2014/03/25/injecting-computation-everywhere-a-sxsw-update/ with all it's nice little demos. I was realy interested in those with astronomic informations, but trying these with my own Mathematica I was irritated: Steven Wolfram wrote in the blog: "... You can use the Wolfram Language completely interactively, using the notebook interface we built for Mathematica." So I typed, like he did: In: Sunrise[] Out: Sunrise[] So I didn't get the result in the blog. Same with other demos from the blog. So my question is: How can I use Wolfram Language with Mathematica? And how can I get it? (Yes I know, with indirections (WeatherData) I could do it with Mathematica too, but I wanted to do it like in the blog's demos.)

• Answer:

  Wolfram Language has not yet been released, so we can't say for sure. However it seems likely that the next release of Mathematica will include the new commands that you saw in Wolfram's demo. The alternative would be for Mathematica's language to diverge from the Wolfram Language, which seems like pointless complexity for Wolfram to manage, and such divergence would probably reduce the user base for a language they seem eager to promote.
