[TYPO3-workspace] which hook while publishing?

[Ralph Germershausen]

hi team,
i try to figure out which hook i should use to react on publishing.
processDatamap_afterDatabaseOperations is working fine for live and edit
workspace while editing content elements, pages and so on, but it's not
triggered when i publish.
any other then processCmdmap_postProcess as alterntive?
i need to submit changes after publishing to a semantic search indexer.
