Domain data 'properties'

[robinlindh]

When uploading domain data using the domain module I see that the Metadata has "properties".
What is the intended use for it? Is it up to the application to put whatever is useful there to describe the data, or do we wanna standardise what values to put there?

I can see it being useful for cases where the data is somewhat big and you want to have some extra metadata available to judge whether to download the data. For example a "level of detail" number for topology meshes, or perhaps a rough bounding box for any spatial data to let apps download only data which is nearby where the phone is currently (especially for very large domains).

I would argue that bounding box is also part of the spatial data.
properties is more like something scan_device, scanner_version, some timestamps that describes the spatial data. The things we saved in manifest files can use properties instead.
