This is a basic implementation of a JSON API for Antville using GraphQL.
Add the graphql folder to your claustra directory and enable the claustra in your application’s app.properties file:
# Multiple claustra can be enabled comma-separated
claustra = graphql$ curl -if http://localhost:8080/helma/antville/claustra/graphql -d \
"query=query {site(name: 'blog') {stories(max: 1) {title url created creator}}}"
