Legacy Publisher

PUB · PUBLISHER

inspectLegacyPublisher validates known Publisher Contents signatures and the additional stream set required for Publisher 2002. This is format identification and container inspection, not publication-page support.

What works

The inspector recognizes validated Publisher 97/2000 and 2002 container signatures and returns stream names plus the streams used to validate the result.

• Publisher 2002 requires the Contents, Escher/EscherStm, and Quill/QuillSub/CONTENTS streams.
• The generic metadata API can edit an existing SummaryInformation text property when the replacement fits its allocated space.
• Unknown or incomplete signatures do not produce a successful inspection.

Known limits

The package does not decode publication pages, text frames, images, or layout and does not provide a Publisher document writer.

• Inspection results do not imply page content was parsed.
• Metadata editing is independent of publication content.
• No rendering, page preview, or structural publication edits are available.

Example

import { inspectLegacyPublisher, writeLegacyOfficeMetadata } from '@christophervr/ole2';

const inspection = inspectLegacyPublisher(pubBytes);
if (inspection) {
  console.log(inspection.version, inspection.validatedStreams);
  const updated = writeLegacyOfficeMetadata(pubBytes, 'title', 'New title');
  if (updated === pubBytes) console.log('Metadata was unchanged or unsupported.');
}
