+# Dataspace Profile Context
+
+## Decision
+
+We'll introduce the concept of "Dataspace profile context", which will enable a connector runtime to serve requests for multiple
+dataspaces with potentially different protocol versions, authentication, vocabulary and policies. 
+
+## Rationale
+
+At the moment the EDC connector only supports multiple protocol versions at the same time, by having pluggable
+modules.
+
+The Dataspace Profile Ccontext is an higher-level concept that defines a set of:
+- wire protocol, version and binding
+- authentication protocol
+- policy functions
+- vocabulary (jsonld context)
+- scopes
+- identifier resolution
+
+## Approach
+
+A `DataspaceProfileContextRegistry` service will be in place, on which a `DataspaceProfileContext` can be registered.
+
+By default, there will be an hardcoded context that uses a particular combination of DSP, DSP, vocabulary and so on; such
+version will be useful for testing and samples, but for a production use the adopters must explicitly define and register
+the expected dataspace contexts by extension.
+
+So, for example, if a connector is supposed to support multiple DSP version, there will be the need to explicitly register
+one profile for every version, same will happen with multiple DCP version and so on.
+
+Every profile will be represented by a different protocol endpoint, and it will be advertised in the `.well-known/dspace.version`
+endpoint.
+
+### Additional Notes
+To be backward compatible, the `profile` information will be passed to management-api and stored as `protocol`, so out of
+the box the default profile name will be the DSP version. In the future this could be adapted and the `protocol` attribute/field
+could be renamed to `profile`, but there's no urgency to do that.
+
+To permit certain assets to be published only on certain profiles the `assetsSelector` field of the `ContractDefinition`
+can be used, no plans to have a strict correlation between Assets and Dataspace Profile Contexts at the moment.
