Data Structure and Computerized Museum Catalogs. Museum Data Bank Research Report No. 2.
The nature of the structure in museum information is explored, and some alternative techniques for maintaining this structure in computerized records are compared. One approach uses structural linguistic concepts to describe relationships in the information from which museum catalog data are extracted and expands these data to an appropriate host language statement. This expanded expression, the full terminal string, can be paraphrased but it cannot be further expanded to change its meaning. The full terminal string from which a catalog record is extracted is hierarchical with various positions called nodes. Relationships between terms in a full terminal string may be relationships of co-occurence--simple dependence, mutual dependence, or mutual exclusion; conjoining; or embedding. These relationships must be retained when extracting catalog data in order to accurately represent the original data meanings. Two approaches for handling these structural relationships when extracting data are compared; one keeps context and structure separate from the extracted catalog data in data category definitions, while the other takes advantage of implied context data, such as general record subjects, and extracts other contexts as part of the data.
