Methods for storing metadata associated with individual files?

Question

Given a collection of files which will have associated metadata, what are the recommended methods for storing this metadata?

Some files formats support storing metad

Answer 1

I would basically make a metadata DB which held this information:

RESOURCE_TABLE
RESOURCE_ID
RESOURCE_TYPE (folder, doctype, web link, other)
RESOURCE_URL (any URL)

NOTES_TABLE
NOTE_ID
RESOURCE_NO
RESOURCE_NOTE (long text)

TAGS_TABLE
TAG_ID
RESOURCE_NO
TAG_TEXT

Then I would use the note field textual notes to the file/folder/resource. Choose if you would use 1:1 or 1:N for this.

The tags field I would use to store any number of searchable parameters like YEAR, PROJECT, and other values that will describe and group your content.

Then you could add tables for owner, stakeholders, and other organisation info etc.
