Nesstar Publisher is an advanced data management program. It consists of data and metadata conversion and editing tools, enabling the user to prepare these materials for publication and make such resources available to a wider audience. The program allows users to enhance datasets by combining a wide range of catalog and contextual information. Users are given, for example, complete control over the structure of the metadata within internationally recognized data documentation schema, including inserting Web links and URLs that can be viewed within the Nesstar Web client. Nesstar Publisher also allows merging of DDI documents containing markup for different sections of the DDI for the same study. This is especially useful for merging in variable description information generated from SPSS/SAS data definition statements or export files with study descriptions and question text.
