A method for tagging content. The method includes receiving an initial metadata tag and associating the initial metadata tag with an object of an online repository. Based on the initial metadata tag, a metadata tag knowledgebase is accessed to derive at least one suggested metadata tag. A confirmation regarding the at least one suggested metadata tag is received and the suggested metadata tag is associated with the object. The object is then uploaded to the repository, and the metadata tag knowledgebase is updated to reflect tags associated with the object.
