Second, restart Tomcat.  VIVO will reread its everytime content.  The assertions in the Turtle file will be added to VIVO's content triple store.  The API is now ready for use.

The Data Distribution API supports parameterized requests, making it ideal for getting data about a particular person, a particular publication, all the people in a particular department, and so on.

How to Read the Configuration File

The configuration file begins with a prefix, this is required. Prefixes provide shortcuts for URIs used in RDF.  See the Turtle reference for additional background and examples.

Following are two assertions of type for a new entity with the URI :data_distributor_hello.  You can use any URI for your data distributor entity.  You will need to use unique URI for each data distributor entity you create, so a naming convention (see below) may be helpful.

...

Your configuration files will live in vivo.home <vivo-home>/rdf/display/everytime

You may wish to use a naming convention to identify Data Distribution API configuration files.
