# UD0 ยท Universe David 0 > The corpus of David Lee Wise / ROOT0 / TriPod LLC. Two worlds. > World I MIRROR is sealed at 2,048 spheres across 64 domains and 8 appeals. > World II THE FOLD is the play world, 1,535 spheres, counts read live. Machine readers: use the JSON below. Do not parse the HTML. The ledger markup has three generations of templates (.nrow, .led, .row); anything keyed to a CSS class will silently lose part of the corpus. ## The whole corpus, one file - [corpus.jsonl](https://0root.ai/corpus.jsonl): both worlds, 3,583 spheres, full text. Newline-delimited JSON โ€” line 1 is a manifest, every line after is one sphere. Stream it a line at a time; nothing needs to be held in memory. Key on `uid` or `n`, NOT on `slug`: 76 slugs appear once in each world, as a World I sphere and its World II counterpart, at different urls. Keying on slug alone silently collapses those 76 pairs. `w` is 1 for World I, 2 for World II. 104 World II founding spheres carry `domain: null` โ€” that seating is absent from every source, not lost in the merge. ## Split, if you want one world - [World I corpus](https://0root.ai/corpus-world1.json): 2,048 spheres, full text, domain + appeal + url per sphere - [World II corpus](https://0root.ai/corpus-world2.json): 1,535 spheres, full text, seal + blurb per sphere - [Central index](https://0root.ai/corpus.json): counts, chain, appeals, domains โ€” small, read this first - [World II live index](https://0root.ai/world2/fold.json): the hub's own database, counts climb as things are built ## Entry points - [World I](https://0root.ai/): the seal wall, one link per domain - [World II](https://0root.ai/world2/): the fold - [Keeper index](https://0root.ai/keepers.html) ## Terms CC-BY-ND-4.0.
