Zend Framework: Zend_Service_Amazon_S3 Component Proposal

Table of Contents

1. Overview

Zend_Service_Amazon_S3 is an implementation of the service API and PHP user-stream wrapper for Amazon's Simple Storage Service (S3)

2. References

• Amazon S3 Developer's Guide

3. Component Requirements, Constraints, and Acceptance Criteria

• This component will implement the Amazon S3 API
• This component will use Zend_Http_Client to communicate with S3
• This component will provide the API to use Amazon S3 directly
• This component will implement a user-based stream wrapper for S3 (s3://)
• This component will allow using multiple S3 accounts

4. Dependencies on Other Framework Components

• Zend_Http_Client

5. Theory of Operation

This component will provide Amazon S3 API allowing to store and retrieve data from the Amazon S3 service.

Also, this component will be utilized using the stream_wrapper_register() PHP method to register a new user-based stream interface to S3. This allows the user to utilize existing fread(), fwrite(), fclose(), mkdir(), rmdir(), and stat() methods to directly interface with S3 buckets and objects.

6. Milestones / Tasks
