The document discusses current practices and emerging models of e-portfolios. It notes that e-portfolios can have different classifications and purposes. Identity management is identified as a key issue, as lifelong learners may have multiple identities. A proposed model views e-portfolios as aggregations of various portfolio services available on the web. Policy issues around e-portfolios include guidelines for development, storage, accessibility, authentication, and interoperability. Standards can help enable interoperability but complete agreement is difficult to achieve.
