ESRI seems to be moving away from the sample type viewers and towards the arcgis.com based templates.
ESRI might be just trying to reach a wider market (ie non-ArcGIS Server customers) or make Web GIS more GIS professional friendly, however, I wouldn't rule out the profit motivation in charging customers for arcgis.com accounts.
So it would be a complete mirror image of what ArcGIS.com is but all local.
I believe this is coming with the json representation of a webmap.
We recently documented this spec here:
http://resources.arcgis.com/en/help/arcgis-web-map-json/
{ "isReference": true, "opacity": 1, "visibility": true, "url": "http://services.arcgisonline.com/ArcGIS/rest/services/Reference/World_Reference_Overlay/MapServer" }], "title": "World_Terrain_Base" }
I am seeking an easy way to leverage the power of ArcGIS.com's "builder" website, but for our website running on our own server in our intranet. I see ways to achieve the functionality of webmap id with json referencing item id's. However that seems to do the same thing, call ArcGIS.com, right? I guess this is useful to over-ride individual things that were set on ArcGIS.com? Am I missing something? I do not see what the difference between referencing a single webmap id is, and referencing individual item id numbers. It still calls on ArcGIS.com. Thank you again.
