THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

Background: In early 1.x, we had basic metadata keys that were created somewhat ad hoc. We then added normalized metadata keys based on standards such as Dublin Core, or we at least tried to add namespaces to the metadata keys for specific file formats. To maintain backwards compatibility, we kept the old keys and added new keys. This led to quite a bit of metadata bloat, where we'd have the same information two or three times. In Tika 2.x, we slimmed down the metadata keys and relied only on , say Dublin Core if it existsthe standards-based or name-spaced keys. In the table below, we document the mappings. If you notice any missing, please let us know or update the wiki.
