+/**
+ * A file attribute view that supports reading or updating the owner of a file.
+ * This file attribute view is intended for file system implementations that
+ * support a file attribute that represents an identity that is the owner of
+ * the file. Often the owner of a file is the identity of the entity that
+ * created the file.
+ *
+ * <p> The {@link #getOwner getOwner} or {@link #setOwner setOwner} methods may
+ * be used to read or update the owner of the file.
+ *
+ * <p> Where dynamic access to file attributes is required, the owner attribute
+ * is identified by the name {@code "owner"}, and the value of the attribute is
+ * a {@link UserPrincipal}. The {@link #readAttributes readAttributes}, {@link
+ * #getAttribute getAttribute} and {@link #setAttribute setAttributes} methods
+ * may be used to read or update the file owner.
+ *
+ * @since 1.7
