Year III

• We plan to convene a special workshop on the Alexandria project at the end of Year III to demonstrate the testbed to users, libraries, and computing professionals. Analyze and revise assessment tools. Completion of assessment tools by the end of Year III.

• Development and implementation of the testbed involving unit testing of the components, integration, and system testing. Deployment of the testbed among multiple library sites. Identifying the performance bottlenecks and scalability issues.

• Implement the browsing mechanism for fast data retrieval. Investigate compression techniques for encoding and decoding wavelet coefficients. Complete implementation of the catalogue supporting the data model and language. Design and development of dynamic index structures.

• Complete the implementation of nonlinear image filtering algorithm for applications such as enhancement, hardcopy output, and for image feature detection. Complete the implementation and testing of image registration and fusion algorithms. Complete the implementation of an image indexing system based on image content which uses various image attributes such as texture, color, contour, and image features detected by the proposed nonlinear filters. Integrate the image content based indexing with textual annotation.

• To model and evaluate further enhancements of the system, like local cache, new compression techniques, emerging networks, other datasets, etc. Test and evaluate the authentication mechanism and protocol in the ever expanding system, and make enhancements when necessary.

• Design new parallel algorithms, data structures and storage organizations, taking into consideration the experimental and theoretical results obtained in Year II, to improve performance and generalize applicability.

• From the knowledge gained, articulate or construct a range of alternative incentives, policy approaches, and specific legal arrangements likely to increase access to existing and developing government and commercial spatial databases.
