    Computerized data systems involving materials property data are needed to support advanced methods of engineering design and computer supported manufacturing. The challenge is to transform the data values extant in printed handbooks, journals, reviews, or monographs into a coherent, accurate, reliable, and consistent body of computerized data available both for automatic as well as manual access in support of engineering tasks. In print, the data values are presented through four principal formats: Direct; Paragraphs (text including embedded numerics); Tables (text or tabular numerics or both); and Graphs (point sets, curve sets, or range sets). Generic templates have been developed to identify and record the metadata as well as guide the capture of the common and separate features with the associated presentation logics for the different formats. Procedures for data capture for tables and graphs are described.

    An extensive metadata schema has been developed covering mechanical properties data included in representative sections of the Aerospace Structural Metals Handbook, and Military Handbook 5. When used in conjunction with data input, the local usage of symbols, property, or material names or designations can be allowed and incorporated and still be consistent with an overall metadata structure.
