The ISO Metadata Standards include the capability to add citations to many kinds of external resources. This is very important for providing complete documentation required to understand and reproduce scientific results.

More information is required for understanding data than
discovering or using it.
One useful way to characterize Metadata content is into three groups: discovery, use, and understanding. Discovery and Use Metadata are generally structured in standard ways and are usually available through discovery portals. Understanding metadata can be structured, but many unstructured resources (scientific papers or reports, user guides, data dictionaries, presentations, etc.) are usually required for complete understanding or, even more difficult, reproducibility.
It is useful to differentiate between structured and unstructured resources. I define documentation as all resources that are required to reproduce scientific results. This includes structured and unstructured materials. Metadata, on the other hand, is the structured and standardized subset of the documentation.
The ISO TC211 Metadata Standards (19115, 19115-1, 19115-2, 19157) acknowledge the existence and importance of unstructured documentation that supports discovery and include explicit citations to those materials. These citations provide links to information about:
1) the metadata standard,
2) metadata for the same resource in other dialects (standards),
4) sources of keywords used in the metadata,
5) additional documentation for the resource described in the metadata.
The ISO TC211 Metadata Standards (19115, 19115-1, 19115-2, 19157) acknowledge the existence and importance of unstructured documentation that supports understanding and include explicit citations to those materials. These citations provide links to information about:
1) associated resources and metadata for those resources,
2) sources used in the creation of the resource being described,
4) references and documentation for software used in the creation of the resource being described,
5) references to the algorithms implemented in the creation of the resource being described.
The ISO TC211 Metadata Standards (19115, 19115-1, 19115-2, 19157) acknowledge the existence and importance of unstructured documentation that supports data quality information and include explicit citations to those materials. These citations provide links to information about:
1) papers or reports that provide information about the quality of the data,
2) reports on tests of conformance of data with relevant standards,
3) quality measures and procedures for applying them.
The revision of ISO 19115 that was just accepted as an International Standard (ISO 19115-1) increases the number of standard citations significantly. This picture shows citation included in 19115 in black and new citations in red.
