IT Consultant: software architect, systems analyst, Enterprise Java web application developer, Drupal CMS web site developer (Phase1)

17/01/2011 - 09/02/2014
IT Consultant, Domain Analyst, Requirements Analyst, Drupal CMS Web Developer

Developed a unique JavaEE web application GreenDesk™ for analysing and tracking the complex data and documentation required for preparing applications compliant with the Green Star™ Office sustainable building rating system of the Green Building Council of Australia (GBCA).

The system uses Expert System technology in Java as an intermediary between rich interactive web user interface worksheets and model views using JavaServer Faces (JSF), and an underlying Enterprise Java domain entity database model - the Building Project Model, created using Parsing Analysis technology to map the Green Star Office specifications to domain model elements and rules.

After initially using an MySQL database with object-relational Java Persistence API (JPA) mapping with EclipseLink, then an object-relational Oracle DB with EclipseLink, a major migration was made to a JPA-compliant pure-object database ObjectDB, with significant improvements.

The PrimeFaces toolkit for JavaServer Faces (JSF) was used to enhance the rich web user interface.

The software engineering included frequent use of graphical Unified Modeling Language (UML) for requirements and domain analysis, model-driven Java design, Java code refactoring, documentation, and even proved useful for freestyle graphics presentations for non-experts. The closely related Systems Modeling Language (SysML) heavily influenced the Building Project domain model.

Custom object-oriented PHP scripting was used to generate Enterprise Java database entity classes directly from a Drupal CMS web site entity-relational database model of the Green Star Office technical manual’s specification for the green office building rating system of the Green Building Council of Australia (GBCA). Such novel and advanced automation of coding is a speciality of Webel IT Australia.

Drupal CMS web site development: Developed a GreenSoft company web site, a web site for the GreenDesk product, and the GreenBase site for resources on global environmental rating schemes.

Prepared investor presentations and held pitch meeting demonstrations for potential investors. Demonstrations included screencast tutorial videos made using ScreenFlow.

Created 3D logos and animated 3D logos using Swift3D.

For demonstrations and examples, please visit the tutorial presentations and demonstration videos of the GreenDesk web application for modelling and environmental compliance tracking of office buildings, developed by Webel for GreenSoft Pty Ltd, Australia.

IT Consultant: software engineer, systems engineer, web developer

27/07/2010 - 16/02/2011
software engineer, systems engineer, web developer

Performed domain analysis using UML Parsing Analysis (sentence-by-sentence mapping of technical text to UML relational and graphical models) of the Green Star Office v3 rating tool spreadsheets into an entity-relationship model and object-relational database representation, using a SysML-like model of domain elements: blocks, attributes, value types, quantities, parts, activities.

Developed a PHP-driven Drupal content management system as a Project Tracking CMS, including a relational parsing analysis of the GBCA Green Star Office v3 rating tool spreadsheets into a cross-navigable domain analysis entity-relationship model. Includes a representation of the credit groups of the Green Star process as activities allocated to human resources.

Performed demonstrations of the developmental ecoSmart web application concept to stakeholders, candidate users, and investors.

[ANNOUNCEMENT]: the JUML project: a Java mapping of Drupal under UML Parsing Analysis of

The prevailing lack in PHP-based Drupal™ of the following technologies (largely perpetuated into Drupal7) drives me (even more) crazy, and it wastes my time:

  • substantial object-orientation
  • flexible method-based hook encapsulation
  • custom type field and user interface inheritance
  • use of GoF and other well known design patterns
  • support for graphical software engineering technologies

If you are an advanced Drupal user with discerning clients, I can assure you that it is wasting your time and money too (even though the software is "free"), and there are much better, well known, well tested ways that have not yet been embraced by the community.

I want to help fix it, and I clearly think that Drupal™ does need a lot of fixing. I (Dr Darren) am a person who can do that, because I am the developer and promoter of the incredibly powerful «wrapper» Component-based UML™ Parsing Analysis analysis recipe, and also develop a powerful recipe I call "snippet-driven" software and systems engineering, a meta-process for document-driven engineering, and because of my current deep involvement with Drupal™, which runs many sites for me and my clients.

As far as I can tell, not one other Drupal user is using such powerful software engineering technologies in combination with their Drupal coding and documentation, and the DrUML and JUML projects are conceived not only to help me, they are conceived to teach you, and to act as as clear examples of what is possible with advanced software engineering process and strategies. I am an evangelist for technologies not yet embraced by Drupal, and I would be delighted to convert at least some Drupal users and developers. I do think needs some salvation.

If I am going to stay with Drupal™ technology, I am going to have to either help reengineer it (which I hope the DrUML project will help achieve for Drupal8), or, perhaps foolishly, I will have to consider forking completely away (given sufficient support and interest from others) to a new Drupal-friendly Java project, which I've decided to call:

JUML: The Java+UML Content Management System

Pronounced 'joo-em-el', with intonation like 'U-M-L', the name is chosen to also sound a bit like both Drupal and Joomla, although in fact all the document mappings are to be from (only).

The JUML project represents a forked design layer for the DrUML analysis project, i.e., once the analysis layer is sufficiently evolved, executable Java components can be generated from them (against my own Webel Java frameworks, and against the Eclipse Modeling Framework (EMF)).

For now, JUML should remain merely an educational example of snippet-based UML™ Parsing Analysis, however by design, it will be able to interact with Drupal sites (and will provide a Swing or SWT interface to them, too). It is not intended (yet) to completely replace or fork from Drupal, and a fundamental requirement is that it should always (!!!) be able to interact with prevailing Drupal sites (at least with my own).

By contrast, the DrUML analysis project is very ambitious, and I want it to cover large portions of crucial Drupal elements.

Moving to some other open source Java CMS projects is not the answer for me, not least because I run so many Drupal sites, but also because the Drupal community is so strong, and there are things about what I can do with Drupal and some contributed modules that I like (and appreciate). I want to amplify the power of that community.

To do this I need snippet-driven engineering and UML™ Parsing Analysis (which manage the mapping from Drupal docs), and I need Java™, because although I can do some reverse engineering of PHP into UML, it requires too much babysitting because PHP is untyped (although, as I've often pointed out, it would be nice if PHP would at least support type-hint annotations, which could be reverse engineered to graphical UML™, it's easy enough to do).

Best of all: JUML is conceived to be able to write PHP against Drupal module APIs, because (my) Java can write PHP ! The graphical UML-based engineering can then be done on the Java components, and when needed, they can write themselves as Drupal friendly PHP (only enough to interact with selected Drupal modules).
