STATEMENT OF WORK (REVISED)

We will conduct a program of basic research in support of educational
technology and emphasize application of transition of ARPA-supported
results in Composable Software Systems.

Required Tasks: Providing Infrastructure Support

- Provide a suite of software tools (``glue'') that are generic
versions of today's ad hoc solutions, e.g., converters, data
interchange formatters, wrappers, filters, and adaptors.

- Provide a rationalization of when to use what type of glue
and in what contexts.

- Identify and build new types of glue.

- Build a type converter server to help automate interoperation
of disparate components.

- Work with other CAETI-funded researchers who are developing
architectures for the educational domain.

Optional Tasks: Application of Infrastructure to Educational Architectures

- Build tool support, including user interfaces, for helping to glue
components together either automatically or with user guidance.

- Demonstrate generality of infrastructure support in the context of
education-specific architectures developed by other CAETI-funded
researchers.

- Design and implement additional, education-specific infrastructure
support needed by CAETI education-specific architectures.
