A matrix is a two-dimensional wizard. Really.

• A hierarchical wizard is a tree-type structure of categories with nodes that lead to "wizard pages".
• A sequential wizard is just a flat step-by-step sequence of "wizard pages".
• A matrix is a row-and-column grid of cells, each of which takes you to a "wizard page".

That's it!

How do I develop a workflow for creating an XSL ePortfolio template inside Sakai and OSP?

This is a two-step process. First you'll need to get your hands on the XML that you'll be creating your XSL for (you do this by creating a pass-through template so you'll have the resulting XML to work with) Second, you can develop the XSL and your XPATH expressions on your local computer with minimal fuss.

Long version:

If you're tinkering with Sakai or its Electronic Portfolio "Open Source Portfolio (OSP)" you might have questions -- or you might find yourself wanting to contribute back to the community (documentation, quality-assurance testing, project management, java or XML coding...)

Open Source Portfolio (OSP) is a set of integrated tools that live inside the full Sakai Collaborative Learning Environment.

OSP and Sakai are both community source projects of the non-profit Sakai Foundation.

See the FAQ: Can I use OSP without using Sakai?

Yes.

Although Open Source Portfolio runs in and depends on the base Sakai collabortative learning environment, you can enable and use OSP tools without turning on or using any Sakai collaboration or course tools.

Alternatively, you can enable and use only those Sakai tools that may be useful in your specific portfolio environment, for example, Sakai's announcements, mailling list/archive or calendaring tools.
