Extending the Dublin Core
- The fifteen basic elements of the Dublin Core are extensible, optional, and repeatable.
- Many implementors have extended these elements through the addition of substructure (AMICO…)
- Others have added whole new elements to the core in order to meet their needs
- The ‘Admin Core’, for example, is aimed specifically at the metadata kept in order to manage data
- where do we stop extending and use something else instead?
