The document discusses Leap2A, a specification for representing e-portfolio information in a common format to allow portability between different portfolio systems. Leap2A was developed through direct involvement of portfolio developers to balance reusability with retaining useful detail. It models a portfolio as a blog-like collection of items that can be categorized, related to other items and resources, and tagged in various ways to maximize the range of learner-owned information that can be transferred between portfolio tools and practices.
