  [resources.params]
    icon = "photo"

{
   "date": "2018-01-25",
   "resources": [
      {
         "name": "header",
         "src": "images/sunset.jpg"
      },
      {
         "params": {
            "icon": "photo"
         },
         "src": "documents/photo_specs.pdf",
         "title": "Photo Specifications"
      },
      {
         "src": "documents/guide.pdf",
         "title": "Instruction Guide"
      },
      {
         "src": "documents/checklist.pdf",
         "title": "Document Checklist"
      },
      {
         "src": "documents/payment.docx",
         "title": "Proof of Payment"
      },
      {
         "name": "pdf-file-:counter",
         "params": {
            "icon": "pdf"
         },
         "src": "**.pdf"
      },
      {
         "params": {
            "icon": "word"
         },
         "src": "**.docx"
      }
   ],
   "title": "Application"
}

From the example above:

• sunset.jpg will receive a new Name and can now be found with .GetMatch "header".
• documents/photo_specs.pdf will get the photo icon.
• documents/checklist.pdf, documents/guide.pdf and documents/payment.docx will get Title as set by title.
• Every PDF in the bundle except documents/photo_specs.pdf will get the pdf icon.
• All PDF files will get a new Name. The name parameter contains a special placeholder :counter, so the Name will be pdf-file-1, pdf-file-2, pdf-file-3.
• Every docx in the bundle will receive the word icon.

The :counter placeholder in name and title

The :counter is a special placeholder recognized in name and title parameters resources.

The counter starts at 1 the first time they are used in either name or title.

For example, if a bundle has the resources photo_specs.pdf, other_specs.pdf, guide.pdf and checklist.pdf, and the front matter has specified the resources as:

resources:
- src: '*specs.pdf'
  title: 'Specification #:counter'
- name: pdf-file-:counter
  src: '**.pdf'

[[resources]]
  src = "*specs.pdf"
  title = "Specification #:counter"

[[resources]]
  name = "pdf-file-:counter"
  src = "**.pdf"

{
   "resources": [
      {
         "src": "*specs.pdf",
         "title": "Specification #:counter"
      },
      {
         "name": "pdf-file-:counter",
         "src": "**.pdf"
      }
   ]
}

the Name and Title will be assigned to the resource files as follows:
