Semantic metadata application for information resources systematization in water spectroscopy

The information and knowledge layers of information-computational system for water spectroscopy are described.Semantic metadata for all the tasks of domain information model that are the basis of the layers have been studied.The principle of semantic metadata determination and mechanisms of the usage during information systematizationin molecular spectroscopy has been revealed. The software developed for the work with semantic metadata isdescribed as well.Formation of domain model in the framework of Semantic Web is based on the use of explicit specification ofits conceptualization or, in other words, its ontologies. Formation of conceptualization for molecular spectroscopywas described in Refs. 1, 2. In these works two chains of task are selected for zeroth approximation for knowledgedomain description. These are direct tasks chain and inverse tasks chain. Solution schemes of these tasks definedapproximation of data layer for knowledge domain conceptualization. Spectroscopy tasks solutions properties leadto a step-by-step extension of molecular spectroscopy conceptualization. Information layer of information systemcorresponds to this extension.An advantage of molecular spectroscopy model designed in a form of tasks chain is actualized in the fact thatone can explicitly define data and metadata at each step of solution of these molecular spectroscopy chain tasks.Metadata structure (tasks solutions properties) in knowledge domain also has form of a chain in which input dataand metadata of the previous task become metadata of the following tasks. The term metadata is used in its narrowsense: metadata are the properties of spectroscopy tasks solutions. Semantic metadata represented with the help ofOWL
