lspace - A personal digital library framework

It is a simple thing right now:

It provides:

• Storage of files of any kind into an sqlite database, keyed by the SHA256 hash of their contents.

  This automatically deduplicates identical files.

• User- and application-specified tagging of the stored files.

• Searching for files by tags (presence, values).

That is it.

Use cases

Intended use cases at the beginning of the project:

• Store my email, have the store searchable.

  • Email "Folders" become labels on the mail.
  • Mail headers are used for tags, again for searching.

  Issue here: No free-form content search however. (Yet?)

• Store my photos, searchable again

  • Exif data expressed as tags.
  • Manual tagging for content (subject(s), location(s), ...)

  Issue here: My pictures take about 400G. (Stored in Timeline/y/m/d hierarchy, i.e. no duplicates). This will be a very big sqlite database. Maybe only use it as index, and keep the files in the filesystem ?
