 Once loaded, RDF mappings can be customized for the needs of a particular site through Drupal's Configuration Synchronization UI at `admin/config/development/configuration`. They can be exported, modified, and re-imported one-at-a-time by choosing the "Single Item" option on the Export/Import tabs.  You can also create new RDF mappings (e.g. for a custom content type) and load them through this interface, by copying an existing mapping and changing the appropriate values.

-    A custom module `rdfui` exists, and is installed-but-not-enabled on boxes provisioned by the claw-playbook. We don't use it because it is very rudimentary and limited to the schema.org vocabulary. There is a project underway to develop a [UI](https://github.com/Islandora-CLAW/CLAW/issues/647) to support RDF mappings to any ontology.

 - A number of namespaces such as `ldp`, `ebucore`, `pcdm`, are `premis` are registered in `islandora.module` using `hook_rdf_namespaces()`. To register your own namespaces, you will need to create a custom module that implements that hook.
 - If you import a configuration that uses a namespace that is not registered, bad things will happen silently.

 Below is an example of an RDF mapping as a .yml (YAML) file. It is the current version of the RDF mapping of the Repository Item (`islandora_object`) bundle, provided by `islandora_defaults` and exportable as `rdf.mapping.node.islandora_object.yml`).
 
 - The top level key `types` specifies the `rdf:type` of the resource or content model. `field_model`, a required field of Islandora objects, also gets mapped to `rdf:type` through an arcane back-end process.
-- The top level key `fieldMappings` specifies fields attached to that bundl,e and their RDF property mappings. One field can be mapped to more than one RDF property. It is a simple flat list.
