EOL JSON-LD not valid #352

Open jhammock opened 8 years ago

jhammock commented 8 years ago

Cloned from https://github.com/EOL/eol/issues/139, courtesy @rdmpage:

The JSON-LD returned by trait bank fails when parsed by the JSON-LD playground, see http://tinyurl.com/hfoos6p

Here's an example http://eol.org/api/traits/10692652. JSON-LD playground complains about "@id": 10692652, an @id needs to be a string (ideally a URI). I would have thought that "http://eol.org/pages10692652" was the obvious value. Fixing that leads to a second problem, 

"vernacularNames": [
      {
        "@language": "en",
        "@value": "Rio Orinoco Spinetail",
        "gbif:isPreferredName": true
      }
    ]

causes the message Invalid JSON-LD syntax; an element containing "@value" may only have an "@index" property and at most one other property which can be "@type" or "@language".

Deleting "gbif:isPreferredName": true fixes that. Once these bugs are fixed, the JSON-LD can be parsed OK.

The JSON shown above is the raw JSON-LD from EOL, below I've shown the edits needed to make it play nice with http://json-ld.org.
