Minecraft wiki entry for Creating_a_resource_pack, associated text: The pack.mcmeta goes in the root folder of your resource pack, not in the assets/minecraft/lang folder. Also note that the above pack.mcmeta is the same file as the pack.mcmeta file that you have created a while ago. As of 1.7-pre, you can choose multiple resource packs at once. If you want to use your new language and resource pack for before 1.7, you need to combine them manually because multiple resource packs could not be selected before the version.
