@kantord - hey, in case the parsing above fails for some reason is it okay with you to have the default variable values here, i.e. empty strings?

[kantord]

you mean specifically for description? I think for description, empty string is a reasonable fallback value, but for displayName I think that using the name as a fallback value would make more sense

[kantord]

also, I'm not very informed about how the BE codebase works, but as I understand the fallback logic happens at insertion time, meaning this code itself does not address existing data in the database. I guess those could be fixed using a database migration or a manual query?

[evankanderson]

I'm pretty sure this code is happening on the way out of the database when answering the query, not on insertion. (That's both what I would expect, and matches the pattern in the code where we're constructing a protocol buffer for output.) If we change 203 to:

pDisplay := pinfo.Name
pDescr := ""

before calling ParseMetadata, that should be sufficient to fill in the defaults when the metadata doesn't exist in the database, without needing a backfill.

Thanks for the suggestion @evankanderson , I've changed the initial values as suggested :)
