It was released to US devs on the 7th of December.
OVER ONE YEAR AGO!
It has been very frustrating not being able to use it. The Built-in Library is talked about in the docs, tutorials written by Amazon, as well as being part of the new Skill Builder.
On the announcement post @thedavedev (Chief Evangelist, Alexa and Echo at Amazon) writes:
"From here, you can search through 145 existing intents in the built-in library. As an example, let’s look at weather."
Wow, that sounds great, really useful.
Then @PaulCutsinger (Amazon Developer Evangelist) presents a series of videos on the Skill Builder
When he gets to the bit about adding an intent he points out the Built-ins (section of the tutorial talking about the built-ins)
"Looks at these, Actor, book, book series, calendars, creative works, episodes.."
Yes Paul, I agree they sound very useful
"Whenever you have the chance, use one of those Built-ins because it's all pretrained for you."
Will do, thanks
"...again use the Built-ins by default if you can.."
So I go off to the developer portal and create a Skill, and instead of the 146 Built-ins talked about, all we see in the UK/DE is...
The type of language used in the tutorials and docs (encouraging developers to use them in their Skills with no mention that it is in "developer preview") give the impression it is production ready.
It is mentioned in the middle of the Understanding the Structure of the Built-in Intent Library with this note:
Have Amazon moved onto a new thing and the Built-in Library no longer being maintained?
Will the new thing be released to US/UK/DE devs at launch or will we go through the same thing again?
Are Amazon planning on withdrawing the Echo from the UK/DE markets and don't want to waste any more resources localising new features?
Have Amazon forgotten they released these things over here?
Because eleven months is a ridiculous amount of time to wait for some software to be localised and released. I expect the whole Built-in Library was developed in less time.
Something else must be going on.
