EpiData Software

Description: 

EpiData is a software package which allows data definitions, data documentation , data entry and analysis based on the project principles in Dublin Core Elements and datadocumentation principles at project and variable level as implemented in DDI standards. Including tools for double data verification and quality assurance measures (restriction of values, labels, comparison of fields, structured jumps, related data files) . Encryption principles and user logging is an option. Version control is implemented as an automatic  counter and with appropriate date registration of changes in structure and data contents. Backup procedures at project level ensures possibility to "roll back" to previous versions.

Following definition, entry and verification of data export can be made to a verified DDI-3.1 XML structure. The DDI export has been verified, funded by and implemented in collaboration with the Danish National Archives (www.sa.dk).

DBKfree

Description: 

The Data Catalogue (DBK) of the GESIS Data Archive holds study descriptions of all archived studies. The software DBKEdit for maintenance and DBKSearch for research in these holdings was developed by the GESIS Data Archive to make this service available. DBKEdit und DBKSearch are distributed as DBKfree to be used by others. Thus, interested users are able to describe their own catalogues on the basis of that and publish them on the web. (Sorry, DBKEdit is German only at the moment).

Description: 

Questasy is a web application developed to manage the documentation and dissemination of data and metadata for panel surveys. It manages questions and variables, including question reuse across multiple studies and longitudinal panels. It also manages concepts, publications, study information, and more. For administrators and project managers, Questasy provides an intuitive interface for managing the metadata. Questasy tracks downloads, and also easily integrates with web tracking applications (such as Google Analytics) to provide detailed statistics on site usage. For researchers, Questasy provides a fast, customizable, easy-to-use web interface for browsing and searching the metadata, and downloading the data. Researchers can also select the variables they are interested in and download a "custom basket" of variables, complete with a custom codebook for their selection. Codebooks are generated in both HTML for browsing and PDF for download/printing.

DDI DExT

Taxonomy upgrade extras: 
Description: 

Tool to import data and DDI metadata from SPSS files with conversion to ASCII and re-export capabilities to SAS, Stata and SPSS. Please note: URL for web site is the direct download link. Optionally for the SPSSReader (exports DDI 2.1 and 3.0): http://odaf.svn.cvsdude.com/ddidext/org.opendatafoundation.data/org-open.... The DDI-DExT (Data Exchange Tools) is a collaborative project between the UK Data Archive and the Open Data Foundation for the development of data archiving and conversion tools. Supported by the UKDA Data Exchange Tools (DExT) initiative, the project aims at the development of open source utilities for the conversion of quantitative data into a standard archiving format and export to common statistical packages or database systems. The application is based on the DDI specification and supports metadata export to DDI 2.0 and DDI 3.0. This initial product is a proof of concept and focuses on SPSS as the input data format with data export capabilities to ASCII, SAS, Stata, and SPSS. The output of the DDI DExT project has been donated to the DDI Foundation Tools Program.

If other, please describe:: 
This is an Eclipse application so should run across OS but was only tested with Windows.
Other system requirements: 
The DDI-DExT application is available for download from the project repository on ODaF Forge. Two packages are made available: the main DDI-DExT application and the SPSS Reader. The DDI-DExT main tool is a stand alone Eclipse RCP application that manages "archive" projects that hold a collection of data files. The data can be imported from most SPSS files and are preserved in fixed ASCI format accompanied by DDI 3.0 based metadata to capture the file and variable level information extracted from SPSS. Archived data files can be redistributed to users for various statistical packages (currently SAS, Stata and SPSS). The export wizard attempts as much as possible to take into account the differences or incompatibilities between the software packages (like variable name lengths, string and date formats, etc.). It also has the ability to simultaneously generate multiple output formats for multiple files and save the resulting files in either a folder or a compressed ZIP file. The output can also contain DDI 3.0 and DDI 2.1 XML metadata for the generated files. The underlying SPSS Reader Java package is also made available for developers interested in exporting data and metadata out of SPSS files. The package has the ability to generate data in fixed, delimited and CSV ASCII formats as well as export metadata in DDI 3.0 and DDI 2.1 XML formats. The package has been tested with a wide range of SPSS files produced on different platforms and varying from version 4 to 16. While minor issues remain to be addressed, the library is capable of reading most SPSS data files.

Nesstar Publisher

Owner: 
Description: 

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.
