Examples of MetaFile

com.hp.hpl.jena.tdb.base.file.MetaFile
Abstraction and many convenience operations on metadata. Metadata is recorded in Java properties style - not RDF - because it's relative to the file or context used. Keys and values are always strings.
org.apache.jackrabbit.vault.vlt.meta.MetaFile
Provides an abstraction for a file of a {@link MetaDirectory}.
org.hive2hive.core.model.MetaFile
Base class for holding meta data for either a large or a small file @author Nico
