File Management

File Manage needs to be flexible and fast.

• File attachments to data items
• Data downloads / exports
• Documentation
• Temp files
• Mapping files
• Image management, generated thumbnails, etc
• Metadata, mimetypes, etc
• Cloud storage
• Efficency
• Security

Current Structure:

- data
-- downloads
-- files
-- mapping
-- tmp
-- uploads

Problems with current structure:

• All files in one directory, can be slow for large volumes
• Thumbnails in same directory, slows performance, harder to maintain
• No versioning
• No expiry

Ideally would have a full File Management system, e.g. Alfresco, CCMS, etc, but not a priority for 2.0 release. Need to plan for moving to advanced model while keeping simple for first release.

• Split files into subdirs with max number of files per dir
• Thumbnails into separate dir, managed by image code (on-the-fly creation, etc)
• Support versioning
• Support expiry date for tmp files
• Support mimetypes + core types (image, video, audio, document)
