What a bookmarked page says about itself, kept beside the bookmark by the member's own client: under the record key of its community.lexicon.bookmarks.bookmark, in the same space and repository, so a reader with either record can fetch the other. It is derived from a fetch of the page and rewritten under the same key when refreshed; a page with no usable image gets none.
