I worked on a project that built a forms tool around XForms about 4 years ago. It is pretty darn powerful, but finding an engine that can understand all that power and run in all the places offline forms need to run is impossible. Maybe there's something in ODK, I haven't dug that deep into the foundational code, I've only looked at it as a potential turn-key solution.
- yanokwa 8y agoODK founder here. The ODK community maintains a Java XForms engine at https://github.com/opendatakit/javarosa https://github.com/opendatakit/javarosa that powers a lot of the ODK tools. https://github.com/enketo/enketo-core https://github.com/enketo/enketo-core is a compatible engine in JS. If you have an idea on how we could make this foundational tech more visible to other devs, shoot me an message!
- jasonkostempski 8y agoI didn't do the initial foundational research for the project I worked on, but now that you mention it, I think that was discussed. I think the main issue was that Java really does run everywhere, except iOS, which is unfortunately the most popular mobile device choice. In an enterprise environment that can dictate what devices get used in the field, it's not a problem, just force Android or even Windows on a tablet. In a bring-your-own-device environment, iOS support is a must-have. On the other hand, bring-you-own-device is a risky business move anyway because App Store rejection is a very real concern. It was a problem more than once for that project.
