Eno is a tool that generates survey questionnaires starting from their formal description in DDI.

Due to its modular design, Eno can create questionnaires in different formats from the same DDI description. Currently, Eno generates XForms web questionnaires that can be executed on Orbeon Forms Runner. PDF questionnaires is under development.

The generation of XForms forms is performed using a number of XSLT transformations from a DDI input managed by a Ant script.

Use the maven dependency to provide the Jar from maven central

See examples in src/test/resources

The main Ant build file is [/src/main/scripts/build_non_regression.xml] and its main target is "full".

This file includes the name forms to generate.

The DDI input and configuration are found in a subdirectory of [/questionnaire/] with the same name.

Generic Ant properties which drive the transformations are stored in [/src/main/scripts/build_configuration.xml]

The generated XForms output will be located in a subdirectory of [/questionnaire/].

• Apache Ant. You can download Ant from Apache, see also : Ant Apache

• Source code from github.com.

Then you have to donwload Java Libraries :

• Ant-Contrib 0.6 or higher (collection of tasks for Apache Ant), see also : Ant contrib
• Saxon HE 9.X or higher (The XSLT and XQuery Processor), see also : Saxon
• Saxon-unpack, included as standard in each Saxon edition
• Common lang 3 or higher (for the non regression test only), see also : Apache Commons lang

Paste the ".jar" file in a "/lib/" folder at the Eno project root.

You can find on the subdirectory [/questionnaire/], the questionnaire example "Simpsons" specified in the DDI format.

To generate the XForms form, execute the main ant build file [/src/main/scripts/build_non_regression.xml]

The generated XForms form should be created in [/questionnaire/simpsons/Xforms/v1/] folder.

The expected XForms form file for the Simpsons questionnaire is present in [/questionnaire/simpsons/] folder, a specific ant target : "full-with-test" generates Xform file and calculates the difference with the expected Xforms file.

The difference file [questionnaire/simpsons/Xforms/v1/diff.txt] specifed, if there has, index at which the file begins to differ and the difference beetwen the generated Xform file and the expected Xform file.

New output format : PDF for paper questionnaire
