   Hi,
   There are several issues involved with the physical organization of the system. The actual physical organization of the data is done by means of a database manager and the user of special keyword tags implemented in the XML DTD. These tags allow the data to be stored, searched, retrieved
   Storage issues
   
   Each document that is stored will be one of two types. It will either be a pointer document that will contain a link to the resource or it will be a summary document that will describe an off-line resource that is available to the disabilities community but has no other Internet presence besides the entry in the database. The keywords that are placed in the documents will be placed at storage time and will help make search, retrieval, and presentation of these resources both accessible and easy. The system will allow modification and addition of the keywords as needs arise.
   Search and retrieval issues
   
   One of the most difficult issues on the Internet today is the issue of searching resources. How do you search such that the results are truly relevant to what you have requested and how do you insure that you are not overwhelmed by the sheer volume of the resources returned. The keyword storage technique is designed to allow quick and accurate searching of the stored resources and in addition a dynamic thesaurus will be developed that tracks all variations of keywords.
   
   A second important consideration is helping the user create a search, or creating a search that does not appear to be a search. We must bear in mind that many of the people who will use this system will have accessibility issues. The search itself must be accessible or the system will lose its utility to the one of the most important segments of the audience we are trying to reach. This issue will be dealt with by means of both accessible forms based searching and searching via the means of drill down questioning. While the second method is not as flexible as the first it does offer those who have trouble with forms an easier method of conduction a search. Since all results will be dynamically produced from stored data, the resources that are presented to the user will be from the latest information available at all times.
   Presentation issues
   
   The storage and retrieval of the data is closely linked to the presentation of the information to the user. An organizational schema that is flexible enough to change and stable enough to allow the user to conduct an effective search will provide the basis for the accessible presentation of the information. If the user does not have relevant information relating to what they are looking for the presentation will make little or not difference. So this can be considered to be the solid base upon which the accessible presentation of the information will rest.
