On the explorer the title appears first, while on the VRE it appears last.
The “Languages” field on the explorer appears as “Language” on the VRE.
The “Size” field on the explorer appears as “Dimensions” on the VRE.
The “Contributors” field on the explorer appears as “edpoprec:contributors” on the VRE.
Sometimes I get the “Search failed: Status code: 500” error message on the VRE for queries that show results on the explorer, and it does not get solved after several tries.
