Motivation[edit]

XRX applications need standards for viewing lists of items as well as HTML view of specific items.

Method[edit]

One of the first functions of most web applications is to provide some way to browse and view data. With XRX application we call these functions list-items and view-item. These are generic XQuery scripts that are located in a views sub-collection of the main application collection. View are by their name, read-only views of the XML data.

Listing Items[edit]

In general, the list-items function must show a brief summary of each record. It is usually displayed in a table view with each column helping to identify a record and distinguish this record from other records. The following are typical requirements of a list-items XQuery

  • Display a single line representation of a record
  • Display the records in a logical order
  • Display columns that help identify the record
  • Allow for pagination for large record sets
  • Provide links to key per-record functions such as viewing the full record, edit or delete

View Item[edit]

  • The view-item query provides a read-only view to a specific record. It required a parameter of the record identifier.
