1. Status definitions

• http://versa-rdf.org/test-status#PROPOSED: This test has been proposed but not yet accepted.
• http://versa-rdf.org/test-status#ACCEPTED: The test has been accepted and all confomring implementations should support it.
• http://versa-rdf.org/test-status#OBSOLETE: The test has beed obsolteted and implementations are no longer required to support it.
• http://versa-rdf.org/test-status#OPTIONAL: The test is optional to any conforming implementation.

2. Datatype definitions

• http://versa-rdf.org/test-datatype#RESOURCE: The URI of a resource.
• http://versa-rdf.org/test-datatype#BOOLEAN: Either the value true or false mapped to a boolean value.
• http://www.w3.org/1999/02/22-rdf-syntax-ns#List: A list, each member of the list is should be an instance of http://versa-rdf.org/test-datatype#list-member. Each list-member will have its own datatype property.

3. Common query format.

• http://versa-rdf.org/test-schema#query-string: The query to perform.
• http://versa-rdf.org/test-schema#namespace: A namespace that needs to be in scope for the query. The element will have a "prefix" and "uri" property that define the namespace mapping.
• http://versa-rdf.org/test-schema#variable: A variable that needs an initial value. The lement will have a "name" attribute that is the name of the variable and the contents of the element are the value. If the element does not have a "datatype" attribute, the datatype of the variable is a string, otherwise it is the datatype sepcified by the attribute.
