You want to build a website featuring the artefacts provided by Holocaust survivors. There are about 20 such people in your project and each of them may provide one or more of each of videos, audios, images, texts.
The site will consist of :
a page for each subject with
- their name,
- their photo,
- possibly bio details provided by project,
- presentation of each artefact associated with that person
- possibly a map with places significant for this person highlighted
a home page
an about this project page
a listing of the people - each a link to that person's page
a map with at least one dot for each person showing a significant location
possibly a table of contents by media type, with each entry linking to the associated person's page

This material will be independent of any copies of the same material held by the library in DSpace.

On occasion, additional people and artefacts may be added to the archive.

In the future, the project may want to develop educational materials based on the archive. That's a separate project, but should be kept in mind in making decisions about organization and identification of documents etc.

I have a sampling of artefact documents (images, videos etc.).

I'll sketch out a plan for the organization of files, necessary metadata etc. to support the desired capabilities and Graphic User Interface.
