This is great to hear. More material to add to http://data.okfn.org/tools :-)

See the readme (https://github.com/QBRC/Guiberest) of this project for more details and examples. We have an additional plugin for handling authentication, if that’s desired.

Of course, please report any issues you find to the relevant project on GitHub so we can improve the quality of the software.

So we are not relying as heavily on the CSV architecture suggested in the Simple Data Format. It shouldn’t be difficult to add, but in the web service model, it made much more sense from the standpoint of performance and simplicity to keep all the data in a single JSON file.

I do like this approach and it provides strong support for getting the
issue on inline data done and merged:

https://github.com/dataprotocols/dataprotocols/issues/36

I should point out you can also have CSV data inline but obviously
JSON is more natural.

Given this seems a strong pattern I wonder if we should have some
extension (or sibiling) to Simple Data Format that does have the JSON
approach - maybe JSON Simple Data Format :-)
