1.   What forms of delivery system                   5.   What are the issues that end-user
     commonality do content providers need                organizations address when considering
     in order to develop content for end user             the following options when developing

2.    How can we classify content providers                a.   "roll their own" on their own,
     (e.g. commercial vendors, non-profit
     open source) and how do their needs and               b.    "roll their own" in concert with other end-
     vested interests vary?                                     user organizations (e.g. in an open source
                                                                initiative),

                                                           d. adopt a well integrated collection of "best-

     organizations (and different end-users                   parts if you take a pejorative view),

               Questions - Continued
6.   What problems or difficulties do
     proprietary, vendor specific, de facto
     standards present?

7.   What useful roles can specification,
     validation, and formal standardization
     organizations play in developing de jure
     standards?

8.   What new problems or difficulties do
     specification and standardization efforts
     present?

9.   What pressures are commercial software
     application suppliers under from both
     content suppliers and end-user
     organizations?

10. What strategies do vendors adopt to
    serve their vested interests, while
    accommodating the interests of their
    suppliers and users?
