摘要： The invention relates to a method, an entity and a system for managing access to data. The data is associated with metadata. At least one predetermined access policy for accessing metadata includes, for each client, at least one identifier relating to the client. An entity receives from at least one client device, a data access request that includes at least one identifier relating to the client. The entity determines, based on the associated access policy, whether the metadata access is authorized. If yes, the entity determines, based on the associated access policy, associated first data allowing to access the metadata. The entity accesses, based on the first data, the associated metadata. The entity accesses, based on the accessed metadata and the associated access policy, at least a part of the associated data, as a late dynamic binding of the metadata with the associated data (or a part of it).
