OCHRE: An Online Cultural and Historical Research Environment

Abstract:  
The OCHRE system is a scalable XML/XQuery system developed originally for archaeological and textual research but applicable to a wide range of disciplines and currently in use by researchers at several different universities (http://ochre.uchicago.edu). Technical support is provided by the Oriental Institute of the University of Chicago. The system is hosted on a native-XML DBMS by the Digital Library Development Center of the University of Chicago Library. It can support many different research projects (currently 20+) and many simultaneous users with sophisticated features for granular access control and record locking. It serves both as a database system for project data management and analysis (in the field and in the lab) and as a large-scale data warehouse for importing, integrating, and querying heterogeneous data recorded by many different projects in accordance with quite different spatial, temporal, and taxonomic ontologies. Its global schema implements a highly abstract upper ontology that has proved to be very efficient and flexible in meeting actual research needs. The warehouse schema is defined in terms of basic types of highly atomized data objects with globally unique keys—e.g., user-defined atomic units of space, time, agency, inscription, discourse, and taxonomic description—which are organized in hierarchies and lists with cross-hierarchy links. The OCHRE ontology (and the scholarly knowledge it models) is characterized by recursive hierarchies of indeterminate depth, hence the value of an XML/XQuery implementation rather than a relational implementation.
