Given the interface below, what would be the best way to contrast the labels from the data labels?
The only thing I could think of would be to shade the background of the labels, however, according to LukeW http://www.lukew.com/ff/entry.asp?1502 background shading is undesirable because it adds visual elements to your layout.
As you can see, if there is any data that is blank then the information looks spread and unorganized.
If the main reason for visiting the page had to be to know the information, then you should improve the contrast in favour of information. Your labels are bold and are dominating the information. You should do the opposite: make the labels less visible (grey, for example) and leave the info black (or make it even bold).
Next thing, in order to make information more readable and understandable you should consider placing the informations that are connected in the proximity of each other. Informations like "name", "address", "state", "zip code" form one group, while the "latitude", "longitude" and driving directions form the other.
I am not sure what is the meaning of informations like "type", "ABC" or "Description", but surely you need to place it and display it with the correspondence to it's importance (for the user).
The technique used at my work currently is to put user-editable data in text boxes in both read-only and in edit mode. In read-only mode, the text boxes are disabled and both the text boxes and their contents are slightly greyed out. If there isn't any data for a particular field, an empty text box is still shown.
In this case, I think adding some kind of visual elements to connect labels and data labels is necessary to give a good visual cue.
