More than ever it's important to ask: r u ODK?
The new ruODK release v1.5.1 now adds support for the OData Dataset Service to the endpoints supporting Entity management added recently in v1.5.0.
The new functions are listed in the package reference.
Again a big shout-out to the core team for providing ruODK with its own test server.
Please feel free to try out the new entity functions of ruODK and let me know here (at-mention me to make sure) or on the ruODK gitHub repo about any bugs or tweaks you'd like to see. Especially the return formats are a tricky beast and there are several approaches - keen to hear what everyone wants and needs.
