CRUD

Yep that's Create, Read, Update, and Delete. Corona uses the term Insert instead of Create but that doesn't keep us from saying CRUD for fun. Corona includes a simple API for CRUD.

To insert a document, send a PUT request to the /store endpoint with the document URI as a parameter. A file extension of .xml, .json, or .txt indicates its type, or you can override with a contentType parameter. For example, to store a JSON document with URI /afternoon-drink.json:

curl -X PUT \ -d '{"name": "Iced Mocha", "size": "Grandé", "tasty": true }' \ 'http://myhost/store?uri=/afternoon-drink.json' To get the document back:

curl -X GET 'http://myhost/store?uri=/afternoon-drink.json'

To update the document, send a POST request:

curl -X POST \ -d '{"name": "Iced Tea", "size": "Jumbo", "refreshing": true }' \ 'http://myhost/store?uri=/afternoon-drink.json'

And to delete the document, send a DELETE request:

curl -X DELETE 'http://myhost/store?uri=/afternoon-drink.json'

Corona provides additional functionality related to CRUD, including

• Retrieving pieces of documents via simplified XPath or JSON Path
• Converting documents during retrieval (for example, to HTML on the way out)
• Managing document metadata (collections, permissions, properties, quality)
• Retrieving (or deleting) documents based on a search

Much of this is covered in the API documentation for the /store and endpoint on the Corona wiki at
