> [!tldr] A fundamental split in [[Notetaking App Types]] - particularly [[Obsidian]] & [[Notion]] / [[Logseq]] Pages are files. Blocks are database records. Pages may contain blocks. Blocks may be whole pages. Both pages and blocks may house metadata. ![[Block Oriented versus Page Oriented 2026-08-07 12.00.27.excalidraw.svg]] %%[[Block Oriented versus Page Oriented 2026-08-07 12.00.27.excalidraw.md|🖋 Edit in Excalidraw]]%% ## Notion [[Notion]] says everything is a block. A page is just a type of a block. Blocks are fundamentally just [[JSON]]. Type specifies how it looks in the interface. The id is just a [[UUID]] V4 ![[Pasted image 20260807104220.png]] ## Logseq [[Logseq]] is an interesting middle ground. Logseq blocks live in files. A file may have several blocks, and blocks are capable of holding their own metadata via [[LogSeq uses per-block metadata]] syntax. ## Obsidian [[Obsidian]] is obsidian. It's file-based and page-oriented through-and-through. You can approximate block behavior some with [[Dataview Plug-in]]. There are some block-like elements like direct-links to sections with headings and to blocks with the superscript notation.^[likethis] **** # More ## Source - https://www.notion.com/blog/data-model-behind-notion
