Import XML/JSON into database

Is it possible to add some .xml import of location data into the Find database.

Imagine that somebody map the place into his own database. It would contain Wi-Fi, accelerometer, magnetometer, gyro, LTE value etc.... And after the mapping it will be time to put the best combination of sampled data into the Find database to get better result (depends on data combination, for example it could be bad idea to put gyro there, but nobody know until get result from localization process :D ). It is slow to put each combination via http request especially if they are about 1000 samples.

The design of xml (or another file) should be similar as api/ Or it could be JSON - one insert per line (this could be the same as api)

Thanks for your interest and time Mike
