Drupal is built…
Standing on the shoulders of…
Each other

Drupal Principles
Modular and extensible. Drupal aims to provide a slim, powerful core that can be readily extended through custom modules .
Quality coding. High quality, elegant, documented code is a priority over roughed-in functionality.
Standards-based. Drupal supports established and emerging standards. Specific target standards include XHTML and CSS.
Low resource demands. To ensure excellent performance, Drupal puts a premium on low-profile coding (for example, minimizing database queries). Drupal should also have minimal, widely-available server-side software requirements. Specifically, Drupal should be fully operational on a platform with a web server, PHP, and either MySQL or Postgresql.
Open source. Drupal is based on the open source philosophy of collaborative free software development and is licensed under the GPL. Drupal is itself open source and builds on and supports other open source projects. Specifically, Drupal is coded in the open source scripting language PHP and supports as primary data sources the open source database formats MySQL and Postgresql.
Ease of use. Drupal aims for a high standard of usability for developers, administrators, and users.
Collaboration. Drupal development supports open, collaborative information sharing systems and approaches.

Contributed Modules
4849 contrib modules in Drupal CVS
Little concrete information on what they do
Most start as solutions to specific problems
Also 570 contrib themes

Curation Tool William Hayes < [email_address] >

Curation Tool
Node import
CCK
Exhibit (using Josh Huckabee's tutorial).
Allows us to import a spreadsheet of a lot of data and have very quick and powerful data filtering/visualization set up very quickly with the ability to curate the data at will which we did not have using Exhibit alone. Of course, once it's set up, adding data manually is pretty easy and we also have the ability to programmatically add new data records.

Drupal 7
Currently in code freeze:
Bug patches only
With a few exceptions
Release when it’s ready
Expanded automated test coverage should shorten cycle
#D7CX pledge http://bit.ly/121D6T - components ready on the day Drupal 7 is released

Drupal 7 changes - General
Install consolidation
Fewer pages with more logical arrangement
Users can cancel accounts!
Improved translation interface
Improved and expanded help integration
Administration theme
More error reporting options

Drupal 7 changes - Theming
Page template XHTML refactored
More semantic class and ID names
Friendlier to CSS only layout
CSS only means no template changes needed (i.e. no PHP)
Better JavaScript cross library integration
JQuery 3.x
Library calls are wrapped
(function($) { $('a').fadeOut().fadeIn(); })(jQuery);

Drupal 7 changes – automated testing
SimpleTest integration
http://testing.drupal.org

Drupal 7 changes - DBTNG
Using PHP data objects (PDO)
Direct support of MySQL PostgreSQL & SQLite
Implied support for others
Transaction support
Replication support (master/slave)
Potential for update automation
Dynamic select queries
Geek alert:
Hook_query_alter replaces hook_db_rewrite_sql

New static select query syntax
Drupal 6:
Drupal 7:
$node = db_query('SELECT nid, title FROM {node} WHERE type = :type AND nid = :nid', array(':type' => $type, ':nid' => $nid))->fetchObject(); $result = db_query("SELECT nid, title FROM {node} WHERE type = '%s' AND nid = %d", array($type, $nid)); $node = db_fetch_object($result);

New dynamic select query:
Drupal 6:
Drupal 7:
$select = db_select('node', 'n')
->fields('n', array('nid'))
->condition('promote', 1)
->condition('status', 1)
->orderBy('sticky', 'DESC')
->orderBy('created', 'DESC')
->extend('PagerDefault')
->limit(variable_get('default_nodes_main', 10))
->addTag('node_access');
$result = pager_query(db_rewrite_sql('SELECT n.nid FROM {node} n WHERE n.promote = 1 AND n.status = 1 ORDER BY n.sticky DESC, n.created DESC'), variable_get('default_nodes_main', 10));

Drupal 7 – Field API
CCK API -> core
CCK UI -> contrib
Not node specific
Use fields in users, etc.
Storage abstraction
Multiple databases (potential)
Amazon S3 (or …)

Drupal 7 – and more…
File API
Files are now first class objects
hook_file_load(), _save(), _move()
Registry
Automatically caches functions, classes, interfaces
$page object
Image handling in core (maybe)

Drupal is not Magic
It will not:
Design your site
Write your content
Keep it up to date
The real limitations are time and money
You must start with a clear idea of what you want to accomplish
Keep your initial install as simple as possible
The beauty of a content management system is that it allows you to keep your site fresh
The hell of a content management system is that, if your content is stale, you have nobody to blame
