ESRI contacted me about this question. After a good talk the conclusion was that it is not wise to build a wrapper around WMS/WFS because of possible changes to the REST interface of ArcGIS Online later. If we want to use ArcGIS Online fully, we just have to use ArcGIS Server. Too bad that we also use OGC-services from external parties. Found no solution for that yet...
----original question---- Our organisation is interested in using ArcGIS Online. We already serve our spatial data using the OGC standards WMS/WFS using Mapserver. Unfortunately, ArcGIS online only works great if you use ArcGIS Server to serve your data. ArcGIS Online only supports the mapping funcionality of WMS, but not the 'GetFeatureInfo' functionality. WFS is not supported by ArcGIS Online at all.
Because migrating all our maps (800+) to ArcGIS Server will be time consuming and expensive I am searching for an alternative.
Do you know of any method to disguise our WMS/WFS services as if they were ArcGIS Server services? I'm thinking about a wrapper of some kind. In theory ArcGIS Online should than be able to use these services as if they were ArcGIS Server services.
Please let me know your thoughts!
