Use common JSON schema for all classifications

[trthatcher]

For consistency, all classifications should follow the same JSON schema. This is the proposed format:

{
    "standard_id": "",
    "version_id": "",
    "name": {
        "en": "English Name",
        "fr": "French Name"
    },
    "abbreviation": {
        "en": "English Abbreviation",
        "fr": "French Appreviation"
    },
    "effective_date": "YYYY-MM-DD",

            }
        }
    ],
