A method for controlling access to metadata or a property in metadata of an electronic object comprises receiving a request from an identified user to access metadata of an electronic object; determining one or more pseudo-users that are allowed to access the requested metadata of the electronic object and their corresponding access modes; retrieving at least one person identity by utilizing at least one property value of one or more properties of the electronic object, which one or more properties correspond to the determined one or more pseudo-users; comparing the identity of the requesting identified user to the retrieved person identities, and if there is a match; providing to the requesting identified user an access to selected properties in the metadata, which selected properties are determined according to the access mode. The invention also relates to a method for defining access to metadata of an electronic object.
