# Things: cross-link to Obsidian and back

> Before we tackle my Things inbox, let's review what it is, and why and how I use it.

Wherever possible I like to link apps to each other. My to-dos for my personal and work life are in Things. And my Small Business System JDex notes are in Obsidian. I help myself out by connecting the apps together.

> I'll just show you how to do this here, but both apps use what's called a [URI scheme](https://kagi.com/search?q=what%27s+a+URI+scheme%3F&r=au&sh=WRbfZmjjXgzDsSknI2XTPg) if you want to explore the concepts further.[^uri]

[^uri]: While technically different, most people use URI/URL interchangeably.

## From Things to Obsidian

1. Get the URL of the Obsidian note you want to link to by right-clicking it and selecting **Copy Obsidian URL**.

   If you're linking from a category-level project, link to the `AC.00` note. In this case I'm linking from `SBS.31` so I'll get the link to note `31.00 List of all marketing, PR, & communications`.

2. In the notes of your Things project, add a Markdown link.

   Things 'supports' Markdown here but doesn't do much with it. You can just paste the link and it'll be clickable. But I like to indicate to myself where I'm going to be taken, so I do the full Markdown syntax by adding `[JDex](link://)`.[^markdown]

   [^markdown]: Let me know if you need more on Markdown links.

## From Obsidian to Things

1. Get the URI of the Things project you want to link to by right-clicking it, selecting **Share…**, and clicking **Copy Link**.

2. In your Obsidian note, add a Markdown link 'above the line'.

   I'll talk about this more in a dedicated post, but I prefer to keep metadata above a horizontal line, and then actual notes below the line. This link counts as metadata.

   As each of the JDex notes already contains a link to 'Open in the Small Business System', add your link to 'Open in Things' directly below.
