Since every element which can have metadata is described with the use of the same metadata set, it is possible to construct a dictionary of the values used in the whole system for a particular attribute in a particular language. Value dictionaries also support the idea of a synonym dictionary (presented in the description of an attribute value dictionary). Describing resources with the use of metadata consists in assigning values (stored in a dictionary) to attributes. If some value does not exist in the dictionary of the given attribute, then, by default, it is added to the system automatically (unless we are dealing with an attribute with a controlled dictionary).

In the attribute value editor (shown in the image below), the user can modify the metadata (bibliographic description) of an object. In the dLibra system, the elements which can be described with the use of attributes are: a directory, an edition, a planned object, and a group object. Bibliographic descriptions of editions, group objects, and planned objects play a role in searching for resources on the website. Also, whenever a bibliographic description is added to a group object, it is propagated to all group objects and editions inside that object. Bibliographic descriptions of directories become the default descriptions of new elements created inside those directories.
