Configuring Landmark ID Generation

By default, Landmark IDs are generated automatically for significant content elements. You can control landmark generation at the paragraph style level using the Style Designer.

Generate Landmark ID

This paragraph style option controls whether Landmark IDs are generated for paragraphs using the style. Located in the Options tab of the Style Designer. Available values are:

  • Auto (default) - ePublisher determines automatically which paragraphs receive Landmark IDs based on content significance

  • Enable - Always generate Landmark IDs for paragraphs using this style

  • Disable - Never generate Landmark IDs for paragraphs using this style

Landmark ID Format

This paragraph style option controls the form of the Landmark ID generated for paragraphs using the style, letting you balance URL stability, compactness, and readability. Located in the Options tab of the Style Designer. Available values are:

  • Hashed (16 char) (default) - Uses the deterministic 16-character BLAKE2b hash described above. Produces stable, collision-resistant URLs and preserves the behavior of earlier releases.

  • Hashed (8 char) - Uses a shorter 8-character BLAKE2b hash for more compact URLs, with a higher (but still small) chance of collisions; suited to small and medium projects.

  • Source ID - Uses the paragraph's authored source ID directly as the Landmark ID — the FrameMaker paragraph ID, DITA element ID, or Markdown++ alias — producing readable, content-meaningful URLs. The source IDs must be unique. This lets you choose which important headings expose stable, human-readable Reverb URLs without authoring a TopicAlias marker on every heading.

Note: For Source ID with DITA input, enable the DITA Adapter's Use source IDs for paragraph IDs option so authored source IDs propagate to the generated paragraphs.

Note: Most users do not need to configure these options. The default Auto generation with the Hashed (16 char) format generates stable Landmark IDs for headings, tables, and other significant content elements automatically.
