ALEG
Stage 3 Implementation Plan

Introduction

Stage 3 of the ALEG Implementation is the development of a prototype system.

Tasks

Step	Task	Description	Effort (range)	Dates (from - to)	Effort (best guess)
1	Database design	Convert the logical design to relational database tables.	2 - 4 days	7 Aug - 11 Aug	3.5 days
2	Install hardware/software	Install + configure hardware, operating system, database, web server, application server environment, Java,...	2 - 4 days	9 Aug - 15 Aug	3.5 days
3	Get basic infrastructure working	JDBC, simple servlets, XML/XSL	1 - 2 days	16 Aug - 18 Aug	1.5 days
4	Trial AUSTLIT Data load	Load the current AUSTLIT data	3 - 4 days	16 Aug - 22 Aug	3 days
5	Trial BAL Data load	Load the current BAL data, perform some automated matching with AUSTLIT	2 - 3 days	22 Aug - 28 Aug	3 days
6	Design and implement basic server-side application infrastructure	client communication (explicit HTML and hidden XML), security, logging, database access & update	10 - 15 days	24 Aug - 15 Sep	13 days
7	Design and implement basic client-side application infrastructure	data maintenance UI framework, data caching, server communication, editting, basic UI design and page structure	10 - 12 days	11 Sep - 29 Sep	10 days

10	Implement basic work/expression/manifestation maintenance	add/edit/delete	4 - 6 days	6 Oct - 13 Oct	5 days
11	Implement basic browsing and searching	Yahoo/Open Directory style browsing and searching	5 - 8 days	13 Oct - 26 Oct	6 days
12	Consolidate above work, incorporate feedback	Ready for Stage 3 evaluation, signoff	3 days	20 Oct - 27 Oct	3 days

This timetable can be graphically represented as:

Note: the above image was taken from a simple (and naive) Gantt chart stored here at Blox.com. The spreadsheet does not allow you to represent part-time spent on a task, so the duration column in the image above is 'elapsed' not 'worked' days.

Significant tasks/functionality not included in the Stage 3 prototype:

1. Extensive AUSTLIT/BAL data matching. Simple (obvious) automated matching will be attempted, but the effort required and possible automated/manual approaches to be persued will be an outcome of the early part of Stage 3.
2. external holdings processing of any type
3. Lu Rees data load
4. EAD retrieval or maintenance
5. update logging
6. user management
