FIELD: information technology.
SUBSTANCE: invention relates to data storage media in computer systems. A user interface, corresponding to a property tree, allows a user to assign metadata properties with values and user data navigation in a system, which includes a storage subsystem, in which data elements are organised and requested for through properties. The property tree includes nodes which show properties of data elements. A user can interact with the property tree so as to assign properties, in which case the value associated with the property in the data storage subsystem is modified. In relation to the property tree, user input can also indicate request to the data storage, in which case a browsed presentation of data elements, corresponding the request, is displayed. The property tree can also display nodes, which represent folders in hierarchical file system, nodes which represent properties with their inherent hierarchy, and nodes which represent user-defined hierarchical properties.
EFFECT: provision for a mechanism for assigning metadata and navigation on these data.
