#note_taking #REPL [Obsidian](http://obsidian.md) is a note-taking software that provides a [[Personal Knowledge Management]] system for organizing and connecting your notes and thoughts. It is designed to work with plain text files, making it flexible and compatible across various platforms and devices. One of the key features of Obsidian is its bidirectional linking capability. It allows you to create connections between different notes by using double brackets around the note's title. These links help in establishing relationships between ideas, making it easier to navigate and explore your notes. The software also supports the use of Markdown formatting, which enables you to add headings, lists, images, code blocks, and more within your notes. This makes it convenient for both writing and structuring your content. Obsidian offers a graph visualization feature called "Graph View." This feature displays an interconnected graph of all the linked notes, allowing you to visualize the relationships between them. It helps in understanding the connections and patterns within your knowledge base. Another notable feature is its search functionality. You can search for keywords or phrases within your notes and quickly find relevant information. The search results are displayed in a sidebar, providing a preview of the matching content. Additionally, Obsidian allows for customization through plugins and themes. You can extend its functionality by installing community-developed plugins or personalize its appearance with different themes. Furthermore, Obsidian provides local storage for your data by default, allowing you to have complete control over your notes without relying on cloud services. However, if desired, you can choose to sync your files across devices using third-party cloud providers like Dropbox or iCloud. Overall, Obsidian is well-suited for individuals who prefer a flexible note-taking system with powerful linking capabilities and customization options. Its focus on interconnectivity makes it an ideal tool for knowledge workers, researchers, writers, students, or anyone looking to organize their thoughts in a structured manner. ## How to use Obsidian? It is particularly convenient to conduct [[Zettlekasten Workflow]] with Obsidian. See [[Zettlekasten]] page for more details. ### Obsidian as a web browser Obsidian is not a web browser itself, but rather a note-taking and knowledge management application. It provides a platform for creating and linking notes, as well as organizing and navigating through them. While it does have some web browsing functionalities, they are limited compared to dedicated web browsers. In Obsidian, you can embed websites or web content within your notes using iframes or HTML code. This allows you to view and interact with the web content directly within your Obsidian workspace. You can also create links to external websites or specific web pages for quick access. However, it's important to note that Obsidian's web browsing features are primarily intended for reference purposes rather than comprehensive browsing capabilities. It lacks advanced features like tabbed browsing, bookmarks management, extensions support, or built-in security measures typically found in dedicated web browsers. Therefore, while Obsidian allows you to interact with the web within your notes and incorporate external resources seamlessly, it is not designed or intended to replace conventional web browsers. Its main focus remains on note-taking and knowledge organization. ## The notion of an Obsidian Link After some trials, I also learned that there is a way to relate to other vaults using Obsidian link: ``` obsidian://open?vault=Homebase&file=PKC ``` As you can tell the protocol name is: `obdidian` , the vault name is: `Homebase`, and the file or note name is: `PKC`. Using this link, one can do the following: ``` [GO TO PKC](obsidian://open?vault=Homebase&file=PKC) ``` [GO TO PKC](obsidian://open?vault=Homebase&file=PKC) # References ```dataview Table title as Title, authors as Authors where contains(subject, "Obsidian") or contains(title, "Obsidian") ```
