All list representations - for example. representations that are list-like in form and contain several elements, such as assetlist, and collectionlist, are paged. Paging uses a request to the server to retrieve only part of the list so the client can gradually scroll or "page" through the content. 

If the list contains very few elements, the paging attribute can have the value null indicating that paging is not available.

JSON format

paging: {
    prev: "",
    next: "/fotoweb/archives/5001-testarchive/;p=1",
    first: "/fotoweb/archives/5001-testarchive/",
    last: "/fotoweb/archives/5001-testarchive/;p=0"

As shown above, the paging attribute has links to previous and next pages, as well as first and last pages.


  • Clients should not compute page URLs but use the available attributes above.
  • Also, do not make assumptions about the number of elements per page. The number of elements may vary; using the attributes above FotoWeb will make the paging work as intended.

Accept headers/media types for collections

Accept header Usage
application/vnd.fotoware.collection+json This media type can only be requested for the first page of a collection. This is because the “collection” media type contains both a list of assets and a list of sub-collections (folders), so it wouldn’t be clear which of those lists is being “paged”.
application/vnd.fotoware.assetlist+json Used for paging of the asset list
application/vnd.fotoware.collectionlist+json Used for paging of the sub-collection list

Paging Attributes

Attribute Description
paging Paging information. Ifnull, the list is not paged, i.e., the representation contains the entire list.

URL of next page. Ifnullor "" (empty string),  there is no next page, and the current representation is the last page.


URL of the previous page. If null or "" (empty string),  there is no previous page, and the current representation is the first page.

paging.first URL of the first page. This attribute is nevernullor ""(empty string),  and can be used for restarting navigation at the beginning of the list.
paging.last URL of the last page. If null or ""(empty string), then the last page is not known because it is not known how many pages there are. The last page (if the list has a finite length) can be “discovered” by following repeatedly.


  • The attributes  paging.first and  paging.last have identical values on all pages, assuming that the contents of the list do not change during iteration

  • If  paging is not  null  for one page, then it is not  null for any page.

  • For the page retrieved from  paging.last is nullor ""(empty string).

  • For the page retrieved from  paging.first paging.prev is nullor ""(empty string).

  • Any page reached from a link has a valid  paging.prev link that links back to its referrer, assuming that the contents of the list do not change during iteration

  • Any page reached from a  paging.prev link has a valid link that links back to its referrer, assuming that the contents of the list do not change during iteration

The contents of some lists may change at any time, so it is recommended to not assume that  paging.last stays the same during iteration.

Important points

Clients should not make any assumptions about:

  • Whether or not a list is paged (i.e., they should always check if  paging is nulland act accordingly).

  • Whether or not  paging.last is null or ""(empty string).

  • The format of page URLs or the meaning of any parts, including, but not limited to, the order of page numbers (increasing or decreasing).

  • The number of elements of a page, or whether or not different pages of the same list have the same number of elements.
