Right now, the platform, as a prototype, will not scale; it's running on NeDB, a simple local version of Mongo; it cannot do full text search even though the instructions suggest that's possible.
SQLite is used in a number of similar projects such as Zotero, and appears easy to drop in there.
That requires a bootstrap function which maps the old NeDB JSON files to SQLite tables.
In a sense, this is a prelude to other backsides for future work.
