XRX/Standard Views
< XRX
Motivation
[edit | edit source]XRX applications need standards for viewing lists of items as well as HTML view of specific items.
Method
[edit | edit source]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 | edit source]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 | edit source]- The view-item query provides a read-only view to a specific record. It required a parameter of the record identifier.
