org.apache.tika.metadata.ReservedNamespaces

public final class ReservedNamespaces
extends Object

Classifies metadata keys by who is allowed to assert them. The Tika-native namespace (tk:) is guarded on the String write route: a key name derived from file content (a blind scrape) that lands in this namespace is a forgery and is refused (thrown) rather than honored, and the public Property factories reject reserved names at construction. This is a file-borne-forgery guard and an internal-bug detector — not a sealed boundary: Metadata.setTrusted(java.lang.String, java.lang.String), Metadata.reconstruct(java.lang.String, java.lang.String, boolean), and Metadata.putAll(org.apache.tika.metadata.Metadata) deliberately write reserved keys for filters, serialization, and pipes user metadata.

Since:

Apache Tika 4.0.0

Method Details

isTikaNative

public static boolean isTikaNative(String name)

Is name in the Tika-native namespace? True for the current tk: prefix and the pre-4.0.0 X-TIKA: prefix — the legacy prefix stays reserved so a crafted file cannot forge it during the 4.x window even though Tika no longer writes it.

Parameters:

name - a metadata key name (may be null)

Returns:

true if the key belongs to the reserved Tika-native namespace
