JsMarc formats definitions

In order to display the meaning of the fields when working with records, JsMarc relies on Marc formats definitions, stored in this folder in the form of JSON files. You might want to ammend those definitions or even add your own. You can do so by creating a JSON file which follows the required structure and add it to the list under ../formats.json.

Structure

{"fields": [
  "3-digits code": {
    "value": "description",
    "ind1":{
      "1-char code": "description",
      ...
    },
    "ind2": {
      "1-char code": "description",
      ...    
    },
    "subfields": {
      "1-char code": {
        "value":"description" //some fields expect contstraints on their value.
                              //if so, form matching pairs expected value -> meaning
                              //otherwise, value is wildcard *
      },
      ...     
    }
  }
