# Link any artifact to any other

> Explicit cross-references between notes, protocols, collections, and attachments — so related work stays connected.

**Shipped 2026-03-16 · Workspace**

Lab work is rarely self-contained. A note references a protocol, which
references a parent project, which has its own attachments. Until now, those
relationships only existed in your head. Bower now lets you wire them up
explicitly.

## What's new

Any artifact can be linked to any other:

* A **note** can link to the protocol it followed and the collection it
  belongs to.
* A **protocol** can link to the collections that use it and the notes that
  ran it.
* A **collection** can link to its parent project and the protocols it
  contains.
* An **attachment** can link to the note it was captured into and any
  collections it's relevant to.

Links are bidirectional — if you link a note to a protocol, the protocol
shows the note in its linked panel automatically.

## Why this matters

Linked entities are the foundation of your workspace's knowledge graph.
They're what lets Bird answer questions like "show me every experiment that
ran the Western blot protocol" or "which notes reference this reagent." The
more you link, the smarter retrieval gets.
