Summary

The Retrieve Form for Data Capture Profile (RFD) provides a method for gathering data within a user’s current application to meet the requirements of an external system. RFD supports the retrieval of forms from a form source, display and completion of a form, and return of instance data from the display application to the source application.

The profile relies upon XForms technology to support negotiation between the form display and form provider systems, so that iterative exchanges can deal with issues like form selection, completion of a series of forms, partial completion of forms, returning to forms partially filled out in earlier sessions. RFD also supports archiving a copy of the completed form.

Use Cases

XForms in General

XForms is an XML application that represents the next generation of forms for the Web. XForms is not a free-standing document type, but is intended to be integrated into other markup languages, such as XHTML or SVG. An XForms-based web form gathers and processes XML data using an architecture that separates presentation, purpose and content. The underlying data of a form is organized into instances of data schema (though formal schema definitions are not required). An XForm allows processing of data to occur using three mechanisms:

a declarative model composed of formulae for data calculations and constraints, data type and other property declarations, and data submission parameters
a view layer composed of intent-based user interface controls
an imperative controller for orchestrating data manipulations, interactions between the model and view layers, and data submissions.

Thus, XForms accommodates form component reuse, fosters strong data type validation, eliminates unnecessary round-trips to the server, offers device independence and reduces the need for scripting.

XForms is a standard developed by the World Wide Web Consortium (W3C).

Simple XForm Example

Pre-population of XForm fields with EHR data

Simple working sample that prefills a data field

This utilizes the capability within XForms to have more than one data instance represented within an XForm's model. One instance contains the instance data to be used to prepopulate a form (with an id of iPropopulate). Once the instances are loaded within an XForm's processor, the values are copied from the propopulate instance into the working instance (to be submitted). This copying is accomplished by setting an event listener for the 'xforms-ready' event, which is dispatched after a XForms is loaded, to set values from one instance to another.
