This is a meta bug about generating and persisting site summaries. Site summaries are exposed on the new New Tab page. They are currently a tile with an image, an icon and some summarized text from the page. This bug is about exploring how we can get those summaries on a connected mobile device. And how we can persist or cache those. This can mean many things, including running a local copy of Fathom, Fathom-like native code, Embedly or calling a hosted Fathom Service to name a few. Whatever we do in a final product needs to be mobile friendly. (Efficient, low energy/battery and bandwidth usage)

I'm personally interested in the persistence story here. Our work on Datomish aims to generalize the kind of limited metadata storage used in the desktop AS add-on: https://github.com/mozilla/activity-stream/blob/master/addon/MetadataStore.js Being JS, Datomish isn't directly applicable to iOS… but we've talked in the past about converging. :jsantell has been doing a lot of work locally in Tofino for extracting cards from pages, including cool stuff like Amazon reviews, which seems to have a lot of overlap with this bug. I encourage you to chat to him about that.

We store things in a metadata table.
