ODaF DeXtris
A generic tool to explore XML statistical metadata


DeXtris is a open source utility whose objective is to facilitate the use and understanding of XML files. It has been designed for simplicity and does not require the installation of extra component. Instead, it runs into standard web browser such as Firefox or Internet Explorer.

To use the software, open any valid XML file on your computer by using the form at the top of the page. For all XML documents, DeXtris provides basic functionalities such as a file overview and the ability to browse the document. You will find DDI 1/2.x and 3.0 sample documents in the "examples" folder under the application installation directory.

The application focuses on metadata standards recommended by the Open Data Foundation for the management of statistical data. Special functionalities have been developed for specifications such as the Statistical Data and Metadata Exchange (SDMX), the Data Documentation Initiative (DDI) (including the draft release of DDI 3.0). Other formats are expected to be supported shortly. When a file from a known namespace is opened with DeXtris, extra information will be provided about the document and specific functionalities will become available. For example, opening a DDI document will allow you to quickly generate a standard data dictionary or search for variables.

DeXtris is in its initial stage of development and your commnents and feedback will play a vital role in future development of the tool. Use the feedback function under the Help menu to report bugs or provide suggestions to the development team.


To install, use the setup program (windows only) or unzip the content of the ZIP file and open the dextris.html file (in the root folder).

Current version is 2007.03
