Fails in the build test.

Seems that the test itself was broken: documentation says that dateModified may be both Date or DateTime, while software/tests/test_basics.py just tested for Date and failed with the "fixed" version of jsonldcontext.jsonld.

tests now breaks for auditDate

Ok, I totally failed to properly check my pull request... Sorry...

But now, I'm a bit confused.

JSON-LD specification says something about expressing a type "with an IRI", as "a term defined in the active context", or "using an array", but omits details about the contents of the array (the only available example contains IRIs, it do not mentions terms).

On the other hand, given my limited understanding of Ruby, seems that json-ld gem only accepts a single string, in form of URI, assigned to type. Arrays seems not to be handled at all, with any content.

I've tried replacing Date and DateTime with schema:Date or fully qualified URLs as http://schema.org/Date, with no success in the validation by the json-ld gem. Probably I'm missing something, but don't know what...

Not sure what value the test_basics for "Date" has and if we should keep it.

Anyone else have some background on test or what should be done?
