What Is CDA PRO Lookup?
This article is the starting point for “user guide” material for CDA PRO Lookup, intended for those wanting instructions on how to use the application.

Refer to the article What is CDA PRO Lookup? for an explanation of what CDA PRO Lookup is, and a high level overview of what you can do with it.

The Main (Only) Screen
CDA PRO Lookup is a single-screen application.

Though it will resize as much as possible for smaller screens or devices, it is easiest to use CDA PRO Lookup with a large screen. There is an option near the top of the CDA PRO Lookup application that looks like this:
In most web browsers, clicking on that box will put the browser into “full screen” mode so that maximum screen real estate is allocated to CDA PRO Lookup while you work.

The CDA Lookup screen is shown below (click on the image to enlarge it):

Two Command Buttons
The top row of the application has two command buttons.

The left-most button is used to open a new tab in the XML Hierarchy Panel (explained below). It is only active when the currently selected node is a template that can be opened in a new tab.

The right-most button is a help button and opens a web page with links to CDA PRO Lookup tutorial material (including this article).

Five Panels
Below the command button row, the screen is divided into five panels. Each panel has a dedicated explanatory article with additional details that you can access by clicking on the panel names in each of the section headers that follow.

Template Hierarchy Panel
The left-most panel, used to search for any C-CDA template (including MU2 document types) and where it fits in the hierarchy of template usage by other templates.

From here, you can directly open any template as a new tab in the XML Hierarchy Panel (see next panel), using the “new tab” command button at the far left of the the command button row at the top, or by right-clicking on the template and selecting “Open Template in New Tab”.

There are two tabs in this panel (the tab selection is done at the bottom), one for search results and one for the actual “Template Tree” that shows the relationships between templates. When CDA PRO Lookup first opens, this panel shows all the top-level C-CDA document and header templates and all the MU2 document types and header template.

XML Hierarchy Panel
Each tab in this panel shows the XML hierarchy of elements for a given C-CDA template (or MU2 document type). There is also a Search tab which can be used to search for any template, XML element, or XML attribute in any C-CDA template (or MU2 document type).

This is the only panel that can’t be collapsed and it is considered the “main” panel of CDA PRO Lookup. It is also the only panel which has a title that is not the panel name but rather the template information for the active tab (or “Search” when the left-most search results tab is active). The number of tabs in this panel is dynamic as each search-result click or opening of a new template tab, opens a new tab.

Attributes Panel
Whenever an XML element is clicked in the active tab of the XML Hierarchy Panel, this panel updates to show the XML attributes for that element.

Links Panel
Whenever an XML element is clicked in the active tab of the XML Hierarchy Panel, this panel updates to show relevant CDA PRO Know articles and CDA PRO Learn learning clips for that element.

Additional Information Panel
Whenever an XML element is clicked in the active tab of the XML Hierarchy Panel, this panel updates to show information from the MDHT model associated with the selected element.

This “additional information” includes the “conformance rules” (formal C-CDA conformance rules or MDHT “pseudo conformance rules” that are implicitly part of CDA or MU2) for both the selected element and its direct child elements. It also includes any “comments” that are in the MDHT model (usually these are taken from the relevant specifications). It also includes the MDHT internal data type and source model.

This panel is collapsed when CDA PRO Lookup first loads and can be clicked on to open it.
