is that it calls your authority into question.

To effectively combat these and other problems, we offer our service ECO. It constantly checks the data that Callisto retrieves for plausibility and corrects errors according to set rules. The time series to be checked is assigned a test profile. Profiles are a set of a series of connected rules. Each rule consists of a test method and, if necessary, a correction method.

When Callisto retrieves new data, it sends a test job to the ECO service. This opens a new thread for the execution of the test and is then immediately available for new test requests. Callisto can thus settle several hundred requests per minute. There is also a periodic check service (for example, once a day) and a manually-triggered one. The latter is useful for interactively determining the parameters of validation rules.
