7. © Copyright 2005 MIT 7 The Content Consumer Choice My apps should just work with the content I need I should be able to “shop around” for and “mix and match” both applications and content I can’t wait for my favorite application to support the content I want. I need to use more than one repository at a time I need a standards based solution

8. © Copyright 2005 MIT 8 The Content Provider Product to Market Consumers should be able to access my content easily I need to liberate my content from dedicated client software My service should be able to survive technology change I need to mitigate cost of technology change My customer required a standards based solution
