Chilkat.Xmp xmp = new Chilkat.Xmp();
xmp.UnlockComponent("anything for 30-day trial");

// Demonstrates how to add/replace an XMP array property
// First, load a JPG (or TIFF) that already contains XMP metadata.
xmp.LoadAppFile("IndependantPhotographer-Example.jpg");

// Get the XMP document...		
Chilkat.Xml xml = xmp.GetEmbedded(0);

// Create a StringArray object that will contain the strings
// to be used for the XMP array property.
Chilkat.StringArray array = new Chilkat.StringArray();
array.Append("chilkat");
array.Append("XMP");
array.Append(".NET");
array.Append("component");

// AddArray inserts an array property into the XMP document.
// If a property with the same name already exists, it is 
// automatically replaced.
// The 2nd argument can be "bag", "alt", or "seq"
xmp.AddArray(xml,"bag","Iptc4xmpCore:Chilkat",array);

// Save the JPG.
xmp.SaveAppFile("modified.jpg");
