iVAULT is the easiest way to add dynamic mapping like ArcGIS online, WMS/WFS and community mapping to your web-map.  iVAULT ArcGIS integrates
seamlessly with these community map services!  These dynamic map services give iVAULT access to attribution and allow iVAULT to link these free map services to other data layers – that your organization may maintain – leaving you with a map that is updated dynamically.

For example, here is the full list of the Esri community maps that can be linked through iVAULT:  http://www.arcgis.com/home/gallery.html
