I need to retrieve the metadata information from a feature layer. I have the web services available and I can run queries to retrieve the feature attributes, but I don't know any method to retrieve the metadata. Is there any sample or code snippet that I can use to understand the method?
Arcgis Server directly cannot serve the metadata for your geographic data.
I believe that ESRI's Geoportal can do so: http://www.esri.com/software/arcgis/geoportal
