Database

Paper [1] proposes a database system that I think we might find useful. They have a similar goal of citizen biological science. Additionally, I found these papers, which could be of use:

For ideas on possible metadata fields this SQL-based system gives a template attribute file ('schema'). Lastly, here are some biological science metadata standards. Sorry I don't know how to approach the database aspect because I'm so unfamiliar with it.

Metadata

Otherwise I'm not sure what other metadata is desired besides the start of recording time and date (in file name) in ISO format, sunrise and sunset times (as file 'attributes') in Unix Epoch format, and a unique and custom identifier (in file name) because the AIFF file inherently saves the sampling rate and number of channels. One possibility I thought was to maintain the metadata format in the file name and have the AIFF file 'attributes' metadata set by LibAiff such that:

  1. longitude -- Name
  2. latitude -- Author
  3. sunset time (Unix seconds) -- Copyright
  4. sunrise time (Unix seconds) -- Annotation

The AIFF library we're using allows four fields of metadata called 'attributes' to be entered (Name, Author, Copyright, and Annotation).

Decided on the ISO 19115 XML format by IOOS. Will use their example metadata as a guide. Will choose desired tags at later date.
