The Doe family consists of mother Jane and her son John. Identifying
people and relationships is an important function of metadata. The ISO
TC211 metadata standards provide a comprehensive framework for many
important metadata use cases. **Could ISO metadata be used to describe
the Doe family?**

ISO metadata describes objects with types and properties. ISO types
generally start with uppercase letters followed by an underscore (MD\_,
CI\_, \...) and have identifiers (id and uuid). Properties are in lower
camel case (e.g. contactInfo) and have references (xlink:href and
uuidref) that link to objects with content for those properties.

In ISO metadata, Jane and John are objects that have types
(CI_Individual) and identifiers (JaneDoe and JohnDoe) which are given as
id properties. Jane has a son (the property) whose identifier is
JohnDoe, indicated with the reference (xlink:href) to JohnDoe associated
with the property of son. John has a mother (the property) named
JaneDoe, indicated by the reference to Jane associated with the mother
property. 

Using identifiers and references simplifies metadata creation and
maintenance, improves consistency, and facilitates reuse of people,
organizations, or citations referenced using links (like web pages)
rather than repetitive content. More about that later.

This blog is included in a series related to ISO TC211 metadata
standards. The goal of the series is to improve understanding and to
examine and compare how the standards are being used by various groups
around the world. Some of the background content was originally
available on the [NOAA GEO-IDE
wiki](https://geo-ide.noaa.gov/wiki/index.php?title=Category:ISO_19115).
It will be updated in this series.
