Abstract:Modern computer systems are based on the traditional hierarchical
file system model, but typically contain large numbers of files with
complex interrelationships. This traditional model is not capable of
meeting the needs of current computer system users, who need to be
able to store and retrieve files based on flexible criteria. A
metadata file system can associate an extensive and rich set of data
with a file, thus enabling more effective file organisation and
retrieval than traditional file systems.
In this seminar we consider current approaches to handling file
metadata, and highlight deficiencies. We introduce a data model for
a database-oriented pure MDFS complete with operations and
semantics. The model supports user-initiated instance and schema
updates and file searches based on structured queries. We also
explore the design space of a set of user interface operations
intended to implement the pure model and facilitate the capturing of
rich metadata. We argue that without such a simple method for users
to create rich metadata, progress in this field will remain limited.
