Tutorial 7: ‘Requirement with Multiple Languages’

Now, let us examine how a value can be given in several languages. The previously discussed requirement has a property indicating it’s priority. Here one of enumerated priority values is provided in english and german language.

{
    "dataTypes": [{
      "id": "DT-Priority",
      "title": "SpecIF:Priority",
      "description": "Enumerated values for priority",
      "type": "xs:enumeration",
      "values": [{
        "id": "V-Prio-0",
        "value": "High"
      },{
        "id": "V-Prio-1",
        "value": [{
          "text": "Rather High",
          "language": "en"
        },{
          "text": "Eher hoch",
          "language": "de"
        }]
      }],
      "multiple": false,
      "changedAt": "2020-03-26T22:59:00+02:00"
    }]
}

Some explanations:

• The first value with “id”:”V-Prio-0” is provided as a string in a single language.
• The second value with “id”:”V-Prio-1” is provided as a list of JSON objects with text and language attributes.
• The language is expected in an abbreviation as defined by IETF, for example “en”, “en/US” or “de”.
• The same applies not only to values of an enumerated dataType, but also to all titles, descriptions and property-values. Try it yourself!
• Which language is chosen in a given situation depends on the application. In case of the SpecIF Viewer, the language setting of the browser is used for selection. If the expected language is not provided by the SpecIF data-set, the first entry in the list is taken.
• To see the effect, klick the link given on the lower right corner of this page, change the language setting of your browser and klick it again.

Let us at last have a look at the full example:
