tags

The tag mappings specified in a tags property consist of:

A name property identifying a DC-X tag
A second property specifying how the DC-X tag is to be set

        tags:
        - name: Creator
          first-of:
          - field: byline
          - meta: author
          - meta: creator
        - name: Title
          meta: title
        - name: body
          template: >
            {%- raw %}
            <p>{{caption}}</p>
            {%- endraw %}
          context:
          - name: caption
            field: caption
        - name: Provider
          first-of:
          - field: credit
          - meta: organizational-unit

The following variations are possible:

```
- name: Creator
  field: byline
```
Assign the value of the uploaded content item's byline field to the DC-X Creator tag.
```
- name: Creator
  meta: creator
```
Assign the value of the uploaded content item's creator metadata field to the DC-X Creator tag.
```
- name: Creator
  first-of:
  - field: byline
  - meta: author
  - meta: creator
```
Read the fields listed under first-of in the specified order. Use the first one that contains a value to set the DC-X Creator tag.
```
- name: body
  template: >
    <p>{{caption}}</p>
  context:
    - name: caption
      field: caption
```
Use the result of executing the specified Jinja2 template to set the DC-X body tag. The context property can be used to define the variables that will be available to the template. These variables can be assigned values in exactly the same way as values are assigned to DC-X tags. So in this example, the {{caption}} variable will be replaced with the content of the uploaded content item's caption field.
