             Summary: Provide a good developer experience for GraphQL Schemas assembled by the Schema Aggregator
                 Key: SLING-10655
                 URL: https://issues.apache.org/jira/browse/SLING-10655
             Project: Sling
          Issue Type: Task
          Components: GraphQL
            Reporter: Radu Cotescu
            Assignee: Radu Cotescu
             Fix For: GraphQL Schema Aggregator 0.0.2


The [GraphQL Schema Aggregator|https://github.com/apache/sling-org-apache-sling-graphql-schema-aggregator] allows assembling and serving GraphQL Schemas to which multiple provider bundles can contribute.

Currently, this still relies on the presence of the {{Sling-GraphQL-Schema}} bundle header in the provider bundles, but this should be replaced by OSGi capabilities and requirements.

The GraphQL Schema Aggregator already provides the following capability:
{code}
osgi.extender;osgi.extender="sling.graphql-schema-aggregator";version:Version="0.1"
{code}

where the version indicates which syntax version of the partial files is supported.

Provider bundles should in turn require this capability:
{code}
Require-Capability: osgi.extender;filter:="(&(osgi.extender=sling.graphql-schema-aggregator)(version>=0.1)((version>=1.0)))"
{code}

and provide in turn a capability indicating the partials they contribute. If they also require other partials provided by other bundles, these should be translated as well into other {{Require-Capability}} entries.
