Zend Framework: Zend_Service_SecondLife Component Proposal

Table of Contents

1. Overview

Zend_Service_SecondLife provides a convenient way to access the Second Life API provided by Linden Labs. Second Life is a virtual reality game.
Currently the API just offers methods to create new accounts.

2. References

*Linden Labs PHP-lib (PHP4 only)
*Second Life API documentation
*Sources in the laboratory

3. Component Requirements, Constraints, and Acceptance Criteria

• Zend_Service_SecondLife will abstract the access to the SecondLife API
• Zend_Service_SecondLife will use Zend_Http_Client for HTTP communication
• Zend_Service_SecondLife will wrap all existant SecondLife API calls
• Zend_Service_SecondLife will not strictly expose the API calls in Zend_Service_SecondLife 1:1
• Zend_Service_SecondLife will normalize API calls and paramater names

4. Dependencies on Other Framework Components

• Zend_Exception

5. Theory of Operation

This component is used to call the Secondlife API. Until now only user registrations are possible. The proprietary SecondLife API protocol is similiar to XML/RPC and therefore a similiar design pattern is used (every value represented by an object).

6. Milestones / Tasks

• Milestone 1: Get feedback
• Milestone 2: Work on prototype in the laboratory
• Milestone 3: [DONE] Working prototype supporting retrieval of valid SL last names, getting error codes, verifying names and creating users.
• Milestone 4: Checkin to the incubator.
• Milestone 5: Unit tests exist, work, and are checked into SVN.
• Milestone 6: Initial documentation exists.
