Update document metadata

Using tokens

Change a document metadata just using JSON tokens.

Check out this JSON:

{
    "title": "Annual report",
    "subject": "Business profitability",
    "creator": "David Navarro"
}

I added the tags {{title}}, {{subject}} and {{creator}} in the document metadata and after applying the JSON, it will be replaced with “Annual report”, “Business profitability” and “David Navarro” accordingly.

Using @metadata object

You can also define a document metadata values using @metadata object at the root of the JSON. For this you need to pass @metadata JSON object along with other data. Documents will automatically detect this @metadata object and apply corresponding values to the document metadata. There is no need to put tokens inside the document “Properties” dialog.

{
    "@metadata": {
         "title": "Some title",
         "description": "Some description",
         "subject": "",
         "creator": "David Navarro",
         "keywords": "",
         "lastModifiedBy": "Plumsail Inc"
    },
  "prop1": "val1",
  "prop2": "val2",
  "propN": "valN"
}

I define all fields in the JSON. If lastModifiedBy and creator fields are not defined then the engine inserts default values Plumsail Inc и Plumsail accordingly.

There is also one rule I need to mention: if the same token is used with the @metadata object and with other tokens in the JSON:

{
     "@metadata": {
         "creator": "admin"
    },
  "creator": "David Navarro"
}

The token has a higher priority than the @metadata object and the creator tag will be replaced with the “David Navarro” value.
