+# Json-Ld Scopes
+
+## Decision
+
+Implement Json-Ld scopes, which are runtime visibility boundaries that enable Json-Ld contexts to be specified for
+different processing contexts. For example, Json-Ld processing for Dataspace Protocol messages and identity-trust
+protocol messages will utilize different Json-Ld contexts. It must be possible to individually specify these contexts.
+
+## Rationale
+
+Currently, Json-Ld processing is handled by `JerseyJsonLdInterceptor` and `JsonLdRemoteMessageSerializerImpl` that are
+registered for each ingess/egress context. On egress, during compaction, `JerseyJsonLdInterceptor`
+and `JsonLdRemoteMessageSerializerImpl` delegate to `TitaniumJsonLd`, which synthesizes a Json-Ld context based on
+namespaces registered using `JsonLd.registerNamespace(String prefix, String contextIri)`. This results in `@context`
+structures containing extraneous information. For example, a registered `DCAT` namespace will be included in the context
+synthesized for identity and trust endpoints, which is never referenced in messages.
+
+Json-Ld scopes will provide a mechanism to avoid extraneous context items by making it possible to limit registration to
+an endpoint context.
+
+## Approach
+
+### Namespace Registration
+
+The `JsonLd` interface will be extended with an overloaded method containing a `scope` parameter:
+
+```
+void registerNamespace(String prefix, String contextIri, String scope)
+```
+
+The scope parameter will identify a Web Context Alias set in the `JerseyWebService`. A `*` value is treated as a
+wildcard to indicate all web context aliases.
+
+The existing `registerNamespace(String prefix, String contextIri)` method will be treated as a `*` wildcard
+registration. This will maintain backward compatibility.
+
+Existing registrations will be ported according to the following table:
+
+| Namespace     | Web Context Alias         |
+|---------------|---------------------------|
+| EDC_NAMESPACE | *                         |
+| DCAT_SCHEMA   | DSP                       |
+| ODRL_SCHEMA   | DSP, MANAGEMENT_API, IATP |
+| DSPACE_SCHEMA | DSP                       |
+
+### Context Registration
+
+The `JsonLd` interface will be extended to support registration of context references. For example:
+
+```json
+{
+  "@context": [
+    "https://example.org/context/v1"
+  ]
+}
+```
+
+The following methods will be added to `JsonLd`:
+
+```
+ void registerContext(String contextIri)
+ 
+ void registerContext(String contextIri, String scope)
+```
+
+The first method variant will register a context reference using the `*` wildcard scope. On compaction, the `JsonLd`
+service will insert references to registered contexts in the synthesized `@context`structure.
+
+### Json-Ld Compaction
+
+Json-Ld compaction will be performed in an egress scope that corresponds to the `JerseyWebService` context alias.
+The `JsonLd` interface will be extended with an overloaded method containing a `scope` parameter:
+
+```
+Result<JsonObject> compact(JsonObject json, String scope);
+```
+
+The existing `Json.ld.compact(JsonObject json)` method will be treated as a `*` wildcard.
+
+Constructors for `JerseyJsonLdInterceptor` and `JsonLdRemoteMessageSerializerImpl` will be updated to include a `scope`
+parameter that will be used for compaction operations.
