I thought it might be interesting to give a brief overview of what features are available in IOTK right now. Since I am continuously developing more will be added and I will attempt to document new features like this from time to time.

API
The IOTK style of programming separates the “back end” PHP API from the HTML, user interface layer, etc. As a result, the data returned from your API functions can be delivered in any format. With minimal effort you can publish an API over HTTP, JSON, REST, XML, etc.

Amazon Web Services
Integration with Simple Storage Service (S3) for things like CDN delivery or file back ups.

Bin
A script repository that contains a large number of scripts for managing your code releases, for providing information about what an Oracle database is doing, and an Oracle error library that explains common Oracle errors in plain English and provides the IOTK standard fix for an issue.

Build
A structured and automated build system.

CLI
A command line interface interface for making script writing and back end job creation easier. One of its main goals is to allow for command line code and functions to be placed inside of your API so that it can be properly unit tested. This system handles things like PID locking, output logging, and providing a mechanism for logging messages and errors to a monitored database.

Code Generator
You build your data structures (SQL) and the Code Generator will handle writing most of the PHP and PL/SQL for you. This is not “stub” code – you can rerun the Code Generator as often as you want and it will not affect the code it created in the past. Furthermore, the system is entirely object oriented so you can expand the Code Generator’s functionality without having to touch what it creates.

Comments
Data structures and code for putting comments into your applications. This feature has been tested for 2 million users commenting on 1 million entities generating 6 million comments. It scales.

Contacts
Contact (address book) management including integration with a third party service for scraping almost all modern email services. The “tell a friend” feature can potentially generate a lot of leads if people use the importer to bring in their entire address book from their email account. This feature has been tested for 3 million entities (users, organizations, address books, etc.) generating 8 million contacts. It scales.

Content
A system for storing, searching, and retrieving large blocks of text content.

DataStore
A generalized file management system that has specialized support for images and video.

Dictionary
Localization support for text.

DNS
A zone file management and compilation system designed for managing a large number of domains and guaranteeing the quality and accuracy of the individual DNS entries.

Documentation
Over 55 documents made up of hundreds of slides that cover best practices, coding standards, scalability issues, product development process, release process, and technical training. In addition a full example API is provided that is written in IOTK standard code that covers the entire system. This code is heavily commented and is provided for more senior developers that just want code references.

Encryption
A simple library for handling encryption of data and armored tokens to make data exchange extremely safe.

Event Log
Typical “feed” functionality common on social sites today. It can also be used to track any type of event within the system you are building.

Examples
A full example API that implements every part of IOTK using standardized IOTK code that is heavily documented.

Form
An HTML form extraction layer that allows for the programmatic creation of forms. This systems also handles all of the tasks involved in form processing and can handle more complicated types like dates, file uploads, etc.

FW
A high availability firewall/load balancer implementation that sits on top of iptables. I am going to write more about this particular feature soon but high availability load balancers are essential for excellent up time and being able to scale requests over many servers. There is, however, another interesting reason I built this which has to do with SPAM prevention challenges that many social sites face today.

Image
A robust image manipulation and delivery system. Put in front of a content delivery network (CDN) this system can save money and time by storing a single image in the file system while being able to deliver it, on the fly, in any orientation. This system sits on top of the ImageMagick graphics library.

Location
Location and geo based data structures and functionality.

Mail Merge
The ability to associate large email lists with email message templates. The templates can be customized based on profile data from the email list.

Oracle
Full integration with Oracle. This has been heavily tested against their amazing 11.0.7.1.0 database.

PDF
A library for converting HTML documents to PDF documents.

Rate
Allows users to rate entities in your system like restaurants or other users. This feature has been tested for 2 million users rating 1 million distinct entities generating 4 million ratings. It scales.

Scheduler
A system for programmatically creating crontab entries from within your API. Eases system administration and back end job processing.

Schema Diff Tool
Compares two Oracle databases and writes the exact SQL scripts required to upgrade the target Oracle database instance so that it is functionally compatible with the source. Extremely powerful tool that makes code roll outs take a tenth of the time and raises the quality on all releases. Using IOTK there is no reason for a person to track what database changes they are making. The system is designed to allow computers to figure it out and inform you what steps to take to get your database up to the latest release.

SEO
Both an API and documentation around good search engine optimization (SEO) practices. A few of the important ones are built into the IOTK framework (like auto-generation of a sitemap.gz file).

Text Search
The ability to add keyword searching to existing tables and LOB based columns.

Tiny URL
Code for shortening URLs so that you can email links without worrying about them breaking lines. More relevant for today to create links that won’t eat up your 140 characters per Twitter status update.

Unit Test
A unit testing framework. Presently IOTK is covered by over 1,200 tests.

User Interface
A host of functionality for standardizing AJAX interactions, enforcing HTML form rendering and processing, enforcing navigation and link creation (for SEO purposes), and for providing a general request handling mechanism that is entirely SEO driven and separates URLs from their mechanism of delivery.

Version
A feature management system for ensuring backwards compatible of your API while allowing you to upgrade libraries and code.

Video
A full video manipulation and trancoding library that sits on top of ffmpeg and mencoder.

XML
An XML processing and creation library.
