Options for merging datasets

[rhiaro]

Simplest is to ask the user to pick one to retain (all data from network A, or all data from network B, no merging/combining).

Set the option for the whole network, or allow user to choose per node/span?

More complicated, so determine if this is useful enough:

• Fill in missing data from one network which is present in the other network (always? sometimes? depends on field? ask user?)
• Merge fields which are amenable to being merged, eg. arrays (always? sometimes? depends? ask?)
• How to combine fields which are single values? (depends? ask?)

I'm thinking, for a simple first implementation, of allowing the user to choose which node/span info to keep whenever they decide as duplicate? E.g. three buttons "Keep A" "Keep Both" "Keep B"

As for merging amenable fields i.e. arrays, I guess we could do that by default. Maybe have a checkbox to not?

Discussion with @R2ZER0 and @odscjen:

We should combine arrays in the consolidated output for:

• networkProviders
• technologies
• transmissionMedium
• internationalConnections

If we're saying this is one cable, these make sense to merge.
