Hi Dmitry. Many thanks for the mockups! They clearly convey the idea, and show each one of the features you listed in the previous thread (here).
The one thing I’m missing (if I’m not mistaken) in the mockups is the bi-directional support, or more exactly the input, manipulation and final write-back of data into the data sources. Looking at the mockups, the management of the dataset metadata along with the metadata of its underlying fields is clearly illustrated - but in addition, I expected a kind of grid-like interface for the management of the actual dataset data. Would the data catalog allow for row-level data management, or would the focus lay with the dataset-level and field-level?
Also, I’m curious how the ‘dependencies’ tab in mockup #2 would look like.
Anyway, count me in for the upcoming call
