In addition to loading map and graph data, Corda Server™ can also display dynamic content supplied by tab-delimited or comma-separated load files. Simply use the %_CNAME (for Column NAME) keyword to specify the dynamic content.
Meta tags are often used with Corda Server's hover capabilities to display dynamic content when a user mouses over a particular data item or map shape in the Image Template file. For more information on configuring Hover objects, see Hover Objects in the Corda Builder™ User Guide.
To specify a meta tag, prepend the %_CNAME keyword to the column heading of the load file you want to extract meta data from. The example below shows a meta tag that is used with the accompanying CSV file to display data from the Phone column in conjunction with a hover object.
Example of a Meta Tag created from a sample .CSV file (Graph)
%_CNAME_Phone
City,Arrivals,Departures,Unused,Out of Commission,Phone,Icon
Atlanta,23,36,11,7,800-897-1910,ATL.gif
Boston,41,17,25,9,800-235-6426,BOS.gif
To use a meta tag, simply add it to the appropriate Text property of the object for which you want to specify dynamic data. For more information on the Text property, see the Corda® 7 Object Reference in Corda Builder.
Important: When loading data from a location other than <document_root>, make sure path.xml reflects this location. For more information, see Setting Path Permissions in the Corda 7 Install and Administration manual.
