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:
|
|
|
|
<!-- #query page where name = "Attributes" -->
|
|
|name |lastModified |contentType |size|perm|pageAttribute|
|
|
|----------|-------------|-------------|----|--|-----|
|
|
|Attributes|1690384301337|text/markdown|1591|rw|hello|
|
|
<!-- /query -->
|
|
|
|
This attaches an attribute to an item:
|
|
|
|
* Item [itemAttribute:: hello]
|
|
|
|
Example query:
|
|
|
|
<!-- #query item where page = "Attributes" and itemAttribute = "hello" -->
|
|
|name|itemAttribute|page |pos |
|
|
|----|-----|----------|----|
|
|
|Item|hello|Attributes|1079|
|
|
<!-- /query -->
|
|
|
|
This attaches an attribute to a task:
|
|
|
|
* [ ] Task [taskAttribute:: hello]
|
|
|
|
Example query:
|
|
|
|
<!-- #query task where page = "Attributes" and taskAttribute = "hello" -->
|
|
|name|done |taskAttribute|page |pos |
|
|
|----|-----|-----|----------|----|
|
|
|Task|false|hello|Attributes|1352|
|
|
<!-- /query -->
