Tags exist on many different entities throughout Resonance, from Collections to Pages. They are used to categorize or apply attributes to the entity they are attached to.

Comma-Separated Tags

Tags can be simple strings, but for more advanced usage, they can also have different levels of grouping separated by commas.


For instance: Category,Key,Value allows you to act on three distinct values. Let's look at these in reverse order.


A tag always has a value. If you provide just the simple tag myTag, then value is myTag, and both category and key are null.

Similarly, the last part of a comma-separated tag is always the value, so myCategory,myKey,myTag also has the value myTag.


A tag doesn't always have a key, but if there are two parts to a tag separated by a comma, the first one is the key: myKey,myValue (myKey)

Similarly, if there are three parts to a tag separated by commas, the second part is the key: myCategory,myKey,myTag (myKey)


Only if there are two commas present does a tag contain a Category. When present, it is always the first part: myCategory,myKey,myTag (myCategory)

What if I want to use a Comma in my Value?

This is possible, if not altogether beautiful, you do this by either providing Category and Key: myCategory,myKey,myTag, withCommas (myTag, withCommas)

Or, you can opt to not provide a Category and Key, but you must provide the commas where they would live: ,,myTag, withCommas (myTag, withCommas)

What about spaces?

You can use spaces inside categories, keys, and values, but any spaces directly after an important comma (the first two) will be removed. (myCategory, myKey, myTag becomes myCategory,myKey,myTag)


Using comma-separated tags is where you start to hit paydirt, as you have two primary advantages using the parsed field:


When you are returning your tags for your given entity, you can optionally filter for a category and/or key, only returning the associated tags:

tags {
parsed(category: "myCategory", key: "myKey") {

Object Return

As you may have noticed just above, you can return tags with their category, key, and value as separate properties of an object:

"category": "myCategory",
"key": "myKey",
"value": "myTag"
