ABSTRACTIn many instances the only source of certain metadata may be in a file saved from some data analysis program. This is an exploration of what metadata can be harvested from several commonly used programs, and therefore by deduction what else is not available from these programs. These metadata elements are mapped into the appropriate DDI 3 structure.
FORWARDThis paper is the product of one of the three working groups at Dagstuhl event 11382. The group was charged with producing a reference model for the process of longitudinal data production and use, with an emphasis on the specification and management of the supporting metadata. This model is designed to be useful for the gamut of study types where data are collected across time, including panel studies and repeated cross-sectional studies. It should also be useful for single cross-section studies.
The Qualitative Data Model Working Group was established in January 2010 with the charge "To develop a robust XMLbased schema for qualitative data exchange (compliant with DDI) and encourage tools development based upon these needs." This report describes the preliminary model developed by that group via online meetings, and working meetings in Gothenburg (2011) and Bergen (2012). This model, described in UML, was developed to cover three main scenarios:1. Qualitative data collections needing metadata at the object level only 2. Qualitative data collections where segments of objects need to be delineated and described and where segments of different physical representations of the same logical objects possibly need to be linked 3. Qualitative data collections as in the second case where related quantitative data have been generated through techniques such as text mining
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
