The document describes the structure for storing metadata for a slideshow presentation. It includes information like the presentation ID, file locations, number of pages, and file formats. It also lists the available image sizes and formats for different components like thumbnails, backgrounds, and transcripts. The metadata structure supports storing additional page-specific data like hyperlinks and original slide sizes.
