Cursored Page Pattern

The Cursored Page pattern adds cursor management affordances to the Page pattern, giving clients cusrsor-style control over the retrieval of the resource’s data.

The Paged resource contains links to the previous and next element in the cursor. Clients can change the cursor configuration with the Cursor resource. These links have different meaning depending on the type of Paged resource.

Data List

In a Data list, the resource presents a list of data points, such as a JSON array. The size of the list in the data page is managed by the size attribute of the Cursor. Each step via next and previous deliver a page of data with size count of elements. A common example is stock price history.

Cursored List

The Paged resource is a List resource with list-entry links to Cursor Entry resources. The number of list-entry links on the Paged resource is managed by the size attrubute of the Cursor. An example would be search results, where each List Entry represents a resource in the result list. The Cursor Entry’s cursorMark gives the client the ability to position the cursor at that entry for further navigation. If a mark cannot be provided on the Entry resource then the client will use the Cursor Info’s cursorMark to reposition the cursor.

Cursored Documents

In this model, the Paged Resource has no size concept; each Page is an element in the cursor, like a carousel. The client will step through the cursor by following the next and previous links.

Changing Cursor Configuration

The client changes cursor configuration by POSTing a new configuration to the Cursor resource. Cursor returns the newly-configured Paged resource URI in its location response header.

If the Paged resource follows the List pattern, then each list entry is a Cursor Entry resource, containing a cursorMark field that identifies that element’s position in the list. This value can be passed to the Cursor resource as a befor or after value to change the cursor position.

Similarly, if the Paged resource presents a data-oriented list of items, like an array of data, those data items should contain a cursorMark field so the client can change the cursor’s before or after point with the Cursor resource.

See the Cursor resource reference for more details on how to change the cursor position and limit.

Paged Resource

profile: <>

See the documentation for Paged resource.



Points to a Cursor Info resource that describes the Paged resource’s cursor configuration and state.

Cursor Info Resource

profile: <>

The Cursor Info resource describes the cursor configuration used in the Paged resource. This resource has the current cursorMark and the limit set for the current cursor.

Property Purpose
cursorMark The current page’s cursorMark. Useful as a before/after value to fetch a new batch of cursored elements.
limit The item count specified when the cursor was created.
size How many elements present on each page. This property applies to data lists and list resources.



Points to a Cursor resource that can configure the cursor pagination.



Points to individual Cursor Entry resources in the List. This relationship is required for paged List resources using the Cursored Page pattern. See the List Entry description for more details about this resource profile.

Cursor Entry Resource

profile: <>,

In a List resource, the cursor entries are individual List Entry resources that contain a field with the entry’s cursor value. This value is used to change the cursor’s position via the Cursor resource. Data lists that use the Cursored Page resource must provide Cursor Entry resources with the cursor property.

Property Purpose
cursorMark The Entry’s cursor value. Useful for changing the pagination configuration with the Cursor resource.

Cursor Resource

profile: <>

The Cursor resource changes the cursor pagination configuration. It is a Lookup resource containing the current configuration. The client can specify a limit on the number of elements fetched for the cursor and either the before or after cursorMark to select a different cursor point to navigate through. They can also set the size of each page to manage the number of elements to present per page. Once the client submits the lookup, the client redirects to the Paged resource configured with this configuration.

Property Purpose
before The cursorMark to view preceding elements from. The element at this cursorMark will not be presented. The Paged resource’s next and previous links will navigate in the same order so that the client will follow the previous link to navigate backwards through the list.
after The cursorMark to view proceeding element from. The element at this cursorMark will not be presented.
limit The number of elements to consume for the cursor. If not present in the lookup, the current cursor limit configuration will be used.
size The number of elements to be present on each page.

If the client only wants to change the page limit, but keep the same cursor position, then they only need to send the limit field in the lookup. If they wish to change the position of the cursor, they supply either the before or after field in the lookup. This cursorMark value comes from either the Cursor Entry resource or the cursorMark property of an element in a resource’s list data.
