Don't require createdAt in viewer?

[jg10-mastodon-social]

This is again a rather niche feature request. I created a file with several movies that didn't have <http://purl.org/dc/terms/created> defined. The viewer failed to load because Cannot read properties of undefined (reading 'getTime')

media-kraken/src/services/Viewer.ts

Line 111 in 3d87fa6

.sort((a, b) => b.createdAt.getTime() - a.createdAt.getTime())

The file successfully loaded when the required triples were added.

This seems to be the only use of createdAt, so it would be nice if the viewer was robust to the triples being missing 🙂

Thanks for pointing this out, I would even go as far as saying that this is a bug. Media Kraken is still using and old data model where the timestamps are triples of the main resource (usually "#it"). But since Umai, I've started using a separate metadata resource to track all of this (usually "#it-metadata"), and it's indeed optional if it doesn't exist. I'll make sure to check this out when I migrate to the new data model, probably when I migrate to Aerogel. Not sure when that'll happen though!
