 ## OSGI support
 
 The [OsgiGraphQLServlet](https://github.com/graphql-java/graphql-java-servlet/blob/master/src/main/java/graphql/servlet/OsgiGraphQLServlet.java) uses a "provider" model to supply the servlet with the required objects:
-* [GraphQLQueryProvider](https://github.com/graphql-java/graphql-java-servlet/blob/master/src/main/java/graphql/servlet/GraphQLQueryProvider.java): Provides query objects to the GraphQL schema.
-* [GraphQLMutationProvider](https://github.com/graphql-java/graphql-java-servlet/blob/master/src/main/java/graphql/servlet/GraphQLMutationProvider.java): Provides mutation objects to the GraphQL schema.
+* [GraphQLQueryProvider](https://github.com/graphql-java/graphql-java-servlet/blob/master/src/main/java/graphql/servlet/GraphQLQueryProvider.java): Provides query fields to the GraphQL schema.
+* [GraphQLMutationProvider](https://github.com/graphql-java/graphql-java-servlet/blob/master/src/main/java/graphql/servlet/GraphQLMutationProvider.java): Provides mutation fields to the GraphQL schema.
 * [GraphQLTypesProvider](https://github.com/graphql-java/graphql-java-servlet/blob/master/src/main/java/graphql/servlet/GraphQLTypesProvider.java): Provides type information to the GraphQL schema.
 * [ExecutionStrategyProvider](https://github.com/graphql-java/graphql-java-servlet/blob/master/src/main/java/graphql/servlet/ExecutionStrategyProvider.java): Provides an execution strategy for running each query.
 * [GraphQLContextBuilder](https://github.com/graphql-java/graphql-java-servlet/blob/master/src/main/java/graphql/servlet/GraphQLContextBuilder.java): Builds a context for running each query.
