Methods and systems are described for providing access to metadata for an identified resource. Information identifying a resource and a resource domain of a resource provider of the resource is received. A metadata access request (MAR) having the information is generated and transmitted for routing based on the resource domain to a resource directory node for accessing a record associating the resource with metadata for the resource where the metadata is in a domain represented by a metadata repository node. An accessor for accessing the metadata is received in response to the MAR. In another aspect, an update message identifying a resource and a metadata-schema domain is received. A record associating the resource and domain is updated. A response including an accessor based on the domain for accessing the metadata for the resource identified by the metadata access request is generated and transmitted as a response to the MAR.
