Collection/Item Metadata Relationships

Contemporary retrieval systems, which search across
collections, usually ignore collection-level metadata. Alternative approaches,
exploiting collection-level information, will require an understanding of the
various kinds of relationships that can obtain between collection-level and
item-level metadata. This paper outlines the problem and describes a project that is
developing a logic-based framework for classifying collection/item metadata
relationships. This framework will support (i) metadata specification developers
defining metadata elements, (ii) metadata creators describing objects, and (iii)
system designers implementing systems that take advantage of collection-level
metadata. We present two simple examples of collection/item metadata relationship
categories, attribute/value-propagation and value-propagation, and show that even in
these simple cases a precise formulation requires modal notions in addition to
first-order logic. These formulations are related to recent work in information
retrieval and ontology evaluation.
