Describe scoped context with @base for id map?

[azaroth42]

Adding @base as a scoped context below an id map makes the structure much more useful:

    "post": {
      "@id": "schema:blogPost",
      "@container": "@id",
      "@context": {
        "@base": "http://content.com/posts/"
      }
    }

As then the URIs become relative to base, and can thus be simple keys / slugs.

Irrelevant as in no longer works? (And if so ... wouldn't that be a normative change?)
Or irrelevant as in this could be a best practice, but not needed in the spec?

No, it's relevant.

It might be considered a bug, but the algorithm doesn't set the local context when processing id-map keys, it is deferred until processing values, thus your example won't work.

We could (probably should) add a step after 13.8.3.1 to set map context if @container includes @id; I'm not sure why we didn't do this.

This will require more tests for this.

In the mean time, I'm just going to update the example to set @base in the top-level context.

[azaroth42]

Hmm, then I'm doubly glad I found it, as it works in the playground just fine!
