A method, comprising - connecting one or more data repositories (EXT1-EXT6) to a centralized content management system by means of connector components interacting with technical interfaces of said one or more data repositories; - analyzing content of data items being stored in said one or more data repositories to identify a subset of data items that should have centralized content management metadata; - creating centralized content management metadata for data items, the creating comprising; ∘ automatically processing content of a data item to result in one or more metadata property values, which one or more metadata property values have not existed for the corresponding data item in the data repository, and which metadata property values at least partly describe the content of the data item; ∘ creating centralized content management metadata from the resulted one or more metadata property values, and ∘ associating the created centralized content management metadata with said data item; - determining when said data item is moved from an original data repository to another location, whereupon the method comprises adding a reference to the original data repository, said reference pointing towards the data item in said another location; wherein the centralized content management metadata further includes one or more references from at least one data item in at least one data repository to at least one other data item in at least one other data repository. - connecting one or more data repositories (EXT1-EXT6) to a centralized content management system by means of connector components interacting with technical interfaces of said one or more data repositories; - analyzing content of data items being stored in said one or more data repositories to identify a subset of data items that should have centralized content management metadata; - creating centralized content management metadata for data items, the creating comprising; ∘ automatically processing content of a data item to result in one or more metadata property values, which one or more metadata property values have not existed for the corresponding data item in the data repository, and which metadata property values at least partly describe the content of the data item; ∘ creating centralized content management metadata from the resulted one or more metadata property values, and ∘ associating the created centralized content management metadata with said data item; ∘ automatically processing content of a data item to result in one or more metadata property values, which one or more metadata property values have not existed for the corresponding data item in the data repository, and which metadata property values at least partly describe the content of the data item; ∘ creating centralized content management metadata from the resulted one or more metadata property values, and ∘ associating the created centralized content management metadata with said data item; - determining when said data item is moved from an original data repository to another location, whereupon the method comprises adding a reference to the original data repository, said reference pointing towards the data item in said another location;
