Mapping Metadata

Map source metadata to EXIF tags

The most important feature of Capturebot is assigning metadata from your datasource to EXIF tags. This is done by mapping a source field to the destination tag.

As long the document isn't locked mappings can be added, removed, and modified.

Adding & Removing Mappings

To add a new mapping, click the + button on the right-hand side of an existing mapping, this will insert a new row below the one you selected.

To remove a mapping, click the - button on the right-hand side of a mapping. There must always be at least one mapping, so you can't remove them all.


Mappings can be dragged and dropped to reorder them. This doesn't affect how mappings are applied, and is only a visual ordering.


Each mapping has at least three options:

  1. Source field
  2. A conversion style
  3. A destination tag

Source Field

The source field is what your original datasource calls a piece of metadata. This might be entered by hand into a spreadhseet, exported from a FileMaker database, or anything else. Each source field and be used in as many mappings as you'd like.

Conversion Mode

This is an important feature for ensuring metadata is valid. There are two options: to use the unmodified source value or to convert the value to an array.

The first does what it says on the tin: it passes the value from your datasource directly to the EXIF tag. Some values are automatically converted, like numbers for star ratings or color tags.

Converting to an Array

Convert the value to an array is used for metadata fields than can contain a list of items, like keywords or IPTC supplemental categories. Formatting metadata correctly is important for searching and ease of use later. When this option is selected a new option is added: the array delimiter.

By default Capturebot uses a comma to split strings, but the delimiter can be anything you'd like.

For instance, a string representing keywords exterior,summer,building,clouds would be converted into an array:

  • exterior
  • summer
  • building
  • clouds

and appear in Capture One as
