Im getting a specific web resource via a http request using GET method.

I've implemented the server to respond using the hypermedia type collection+json so every response is a collection of items according to the specification (http://amundsen.com/media-types/collection/format/#query-templates)

Since the client is requesting a specific item, what should be the content of the href of the collection?

I think it should be the same url of the single item, but I'm not sure.

According to http://www.w3.org/TR/html4/struct/links.html#adef-href, "This attribute specifies the location of a Web resource, thus defining a link between the current element (the source anchor) and the destination anchor defined by this attribute."

If we are requesting the specific element is because we already know its url, then it would be optional to set this attribute. However, it is important to be consistent. If all the other responses of our API include "href", then it would be expected to include this attribute and the value of it could be the same url of the object we want to get.

  • Good. Then I find it a little redundant in collection+json particularly to specify the url for the collection AND for the only item in the collection. – juanpavergara May 25 '13 at 19:50

In case the specific item belongs to a collection, the URI of the collection. In case the item does not belong to a collection (which could be odd and maybe you may check the design of your API) the URL of the item.
