Attributes can contribute additional Metadata to various entities:

• Pages
• Items
• Tasks

Syntax

The syntax is as follows:

[attributeName: value]

For Obsidian/LogSeq compatibility, you can also double the colon like this: [attributeName:: value]

Attribute names need to be alphanumeric. Values are interpreted as YAML values. So here are some examples of valid attribute definitions:

• string: [attribute1: sup]
• number: [attribute2: 10]
• array: [attribute3: [sup, yo]]

Multiple attributes can be attached to a single entity, e.g. like so:

• Some item [attribute1: sup][attribute2: 22]

Scope

Depending on where these attributes appear, they attach to different things. For instance, this attaches an attribute to a page:

[pageAttribute:: hello]

Example query:

name	lastModified	contentType	size	perm	pageAttribute
Attributes	1690384301337	text/markdown	1591	rw	hello

This attaches an attribute to an item:

• Item [itemAttribute:: hello]

Example query:

name	itemAttribute	page	pos
Item	hello	Attributes	1079

This attaches an attribute to a task:

• Task [taskAttribute:: hello]

Example query:

name	done	taskAttribute	page	pos
Task	false	hello	Attributes	1352
