JSON question

Hi All

I'm experimenting with PostgreSQL's JSON features and have a question.

Say we have the following JSON (which will be stored in a table named 'resources' - in its 'schema' column ...

{
"name": {
"type": "string",
"label": "Name",
"accessor": "name",
"is_association": false
},
"books": {
"type": "array",
"label": "Books",
"accessor": "books",
"is_association": true
},
"email": {
"type": "string",
"label": "Email",
"accessor": "email",
"is_association": false
},
"date_of_birth": {
"type": "date",
"label": "Birthday",
"accessor": "date_of_birth",
"is_association": false
}
}

[NOTE: the JSON above is the 'schema' attribute of one record in the 'resources' table. There will be many rows in the 'resources' table]

How can I query the 'resources' table to return the rows in which there's at least one JSON object whose 'type' equals 'array' ?

Thanks
Dave
