The dev team has tabular dataset support planned for the next major release in July and is interested in hearing about how you'd like Open Data to support this type of dataset.
It would be great if you could please post some comments here about how you'd like to add and work with tabular data -- direct upload of a CSV, referencing a CSV by URL that is already on a web server, sharing directly from Esri Maps for Office, etc.? Which are your most important workflows that you'd like to see supported?
It would be ideal if ArcGIS Open Data were to support any of the data types that are supported by ArcGIS Online.
It would be ideal if ArcGIS Open Data were to support any of the data types that are supported by ArcGIS Online. This includes many non spatial data types. For these types I would suggest that ArcGIS Open Data includes them in search results as per ArcGIS Online. When such formats turn up as search candidates the data footprint/extent should be shown in the map. On clicking the item the User should get the same download option as per ArcGIS Online. It is not usually necessary or possible to visualize these data types geographically but it would be really useful to be able to list, discover and download them.
