Many publication resources that are supported by modern publishing platforms warrant their own description to ensure they are properly credited, interpreted, and rendered with context in the future. Where possible, include descriptive metadata for each resource. Use an existing standard for guidance on what to include, e.g. Dublin Core.
These guidelines add additional context to creating metadata for publication resources:
16. Captions for non-text features add meaningful context
22. Express metadata in an appropriate structured format
25. Express the license information in the resource-level metadata
26. Describe connections between resources in the metadata
27. Assign and use unique persistent identifiers for publication resources
