```
public class LinkedDataFileResource
extends FileResource
```
This class represents a linked data file resource, referenced through an uri. It may be specified additionally (if applicable) by the context definition and the corresponding (object) type.
Examples of LinkedDataFileResources are machine readable resources like Marc, MARC-XML, RDF, IIIF-Manifest, METS, JSON-LD, ....
A linked data file resource may be for example of format JSON-LD (mimetype 'application/ld+json'), e.g. an IIIF Presentation Manifest or an Entity Facts person description, what is the first use case being in focus.

JSON-LD is designed around the concept of a "context" to provide additional mappings from JSON to an RDF model.

The 'context' links object properties in a JSON document to concepts in an ontology.
The 'id' is an Internationalized Resource Identifier, represented by an IRI, which allows the Linked Data FileResource to be unambiguously identified by an IRI. In our implementation we use the 'uri' field of FileResource to be the id.
The 'type' specifies the type of object described in the document.

The 'context' and 'objectType' are optional if no context or objectType is known.
