Description

1. RIOT ignores "base":

curl -s https://gist.githubusercontent.com/VladimirAlexiev/7b26962f9000a22fc25e8d180c716067/raw/7923f25be672294433dc95b48523573429781ecb/eg.jsonld|riot -syntax jsonld -formatted ttl
...
<http://base/attack-pattern--00d0b012-8a03-410e-95de-5826bf542de6> 
  a stix:attack-pattern ;
...

However, that jsonld includes base:

 "@base": "http://attack.mitre.org/enterprise/",

and the jsonld playground http://tinyurl.com/yd25vasq does take it into account: in n3 output see URLs like

<http://attack.mitre.org/enterprise/attack-pattern--00d0b012-8a03-410e-95de-5826bf542de6>

2. Inexplicably, if I take the same jsonld content from a file, I get only triples rooted at blank nodes!
This is a regression, it was not present in an older RIOT (I from a year ago, something like 3.1)

curl -s https://gist.githubusercontent.com/VladimirAlexiev/7b26962f9000a22fc25e8d180c716067/raw/7923f25be672294433dc95b48523573429781ecb/eg.jsonld>eg.jsonld
riot -syntax jsonld -formatted ttl eg.jsonld
...
[ stix:external_id  "T1066" ;
  stix:source_name  "mitre-attack" ;
  stix:url          <https://attack.mitre.org/wiki/Technique/T1066>
] .

If I just add an input redirection to the command line (<), I see a lot more triples.

riot -syntax jsonld -formatted ttl < eg.jsonld
