BSCW objects have a number of metadata attributes that are either set by the user (e.g. name or description), or are set by the system (e.g. creation date or name of creator). Some types of objects may be described using richer sets of named attributes, e.g. documents may be classified using attributes of the Dublin Core Metadata Element Set (title, author, language etc.). Users may even define their own sets of attributes each consisting of a name-value pair, if the BSCW server is configured accordingly.
Another approach to describing and classifying objects is tagging. Here, users describe objects by freely chosen keywords, the so-called tags. A lot of object types in BSCW may be tagged, including folders, documents and users.
Both named attributes and tags may be used in BSCW searches.
