Abstract : The report describes a chemical information and data system in the form in which it was expected to be available for initial experimentation by Army installations on or about 1 May 1967. The description deals primarily with matters referable to structural chemistry. It discloses those structural features that the system presently utilizes to discriminate among chemical compounds, depicts the assignment of keys to these features, and illustrates the use of these keys in the processing of queries addressed to the system. It also discloses certain types of chemical compounds that require further study before they can be incorporated into the system. The kind of nonstructural information and data planned to be incorporated for early experimentation are identified. Matters germane to system configuration, programming, and program execution are scheduled for inclusion in a subsequent report. (Author)
