by Mahara ePortfolio System
What makes Mahara different from other ePortfolio systems is that you control which items and what information (artefacts) within your portfolio other users see.
In order to facilitate this access control, all artefacts you wish to show to other users need to be bundled up and placed onto a page.
You can have as many pages as you like, each with a different collection of artefacts, and intended purpose and audience. Your audience, or the people you wish to give access to your page, can be added as individuals or as a member of a group or community.
ePortfolio owners create pages using a 4-step process, and page have the following features:
- ePortfolio owners can receive public or private feedback on their pages and artefacts within that page.
- Users accessing a page can report any objectionable material directly to the site administrator.
- Users can add pages and artefacts within a page to their watchlist and receive automated notifications of any changes or updates.
- ePortfolio owners can submit a page for assessment by a tutor or teacher allowing for a snapshot of the page and associated artefacts on a certain date.
Within Mahara you can share details through a variety of optional profile information fields including:
- Preferred name
- Student ID
- Postal address and contact phone numbers

Mahara includes a file repository which allows you to:
- Create folder and sub folder structures

- Extract .zip, .tar.gz and .tar.bz2 from within the files area
A comprehensive blogging tool is provided in Mahara, where blogs and blog postings are considered artefacts and may be added to a page.
The blogging tool allows you to:
- Create journal entries using a WYSIWYG editor
- Attach files to journal entries
- Embed images into entries

- Create draft entries for later publishing

Mahara provides a single-sign on capability that allows users, at the option of the administrator, to be automatically logged in to both their Mahara and Moodle accounts by providing a username and password at only one of these sites.
The user can sign on at Mahara, and click on a link to her Moodle account, or sign on at Moodle, and click on a link to her Mahara account.
The single-sign-on feature runs over an encrypted transport, and the user's passwords do not have to be shared between sites.
This product includes software developed by the OpenSSL Project for use in the OpenSSL Toolkit.
- Mahara automatically detects system settings that a pose a security threat.
- Session key handling code has been tightly integrated with the core form/request APIs.
- Provides database abstraction that prevents any database injection attacks and input validation that prevents script injection attacks.
- User authentication can be tied to external systems such as student management systems or other databases such as their Student ID number.
- Mahara includes an Import/Export system with Leap2A suport, and static HTML export.
- Users can place their views under any of the Creative Commons licenses.
- Mahara is built using PHP web scripting language and leverages PHP5's OO features.
- All plug-ins follow a consistent structure and inherit from a common base class (core functions of plug-ins are implemented once)
- Mahara currently supports plug-ins for Artefacts, Authentication and Search. Therefore interoperating with an existing product simply requires the development of a plug-in.
Mahara has been designed as a web application with a plug-in architecture. This means it is possible to scale the application up by separating hardware for search, database, file storage and web servers.
It is also possible to replicate each of these operational components to further scale the system upwards. In addition Mahara is designed to:
- be load balanced across several web servers
- have a share file data from a centralised file server
- and have a separate database server.
This hosting setup has proven scalability for similar systems like Moodle.
