+/**
+ * Contains a core set of basic Tika metadata properties, which all parsers
+ * will attempt to supply (where the file format permits). These are all
+ * defined in terms of other standard namespaces.
+ *
+ * Users of Tika who wish to have consistent metadata across file formats
+ * can make use of these Properties, knowing that where present they will
+ * have consistent semantic meaning between different file formats. (No
+ * matter if one file format calls it Title, another Long-Title and another
+ * Long-Name, if they all mean the same thing as defined by
+ * {@link DublinCore#TITLE} then they will all be present as such)
+ *
+ * For now, most of these properties are composite ones including the
deprecated
+ * non-prefixed String properties from the Metadata class. In Tika 2.0, most
+ * of these will revert back to simple assignments.
