Attribute syntax can contribute additional Metadata to various Objects, including:

• 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 alpha-numeric. 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]

However, usually, Frontmatter is used for this purpose instead.

Example query:

page where name = "{{@page.name}}" select name, pageAttribute 

This attaches an attribute to an item:

• Item [itemAttribute: hello] #specialitem

Example query:

specialitem where itemAttribute = "hello" select name, itemAttribute 

This attaches an attribute to a task:

• Task [taskAttribute: hello]

Example query:

task where page = "Attributes" and taskAttribute = "hello" select name, taskAttribute
