One of a quick way to create a MOC in Obsidian is to make a single-line dataview query as the following:
```dataview
list from [[]] and !outgoing([[]])
```This query generates an inbox of items that are open for further manipulation. The clever aspect is that once an outgoing link to an item is created, it is automatically removed from this list.
We can also add tags. This will often include the current page, so we need to explicitly exclude that:
```dataview
list from [[]] or \#tag and !outgoing([[]])
WHERE file.name != this.file.name
```
