I downloaded restricted areas shapefile from here:
It came with a rst.html file, which, on opening, displayed a page exactly the same as the 'Description' tab in ArcCatalog. Enthused, I imported this file into ArcCatalog, hoping it would transfer all the information automatically. Unfortunately, however, it only imported the bounding box coordinates and put the name of the shapefile as the heading.
Anyone know what went wrong?
