Open Knesset committee data currently includes the names of lobbyists (committees_committeemeeting_lobbyists_mentioned) and the lobbyist corporation that employs them (committees_committeemeeting_lobbyist_corporations_mentioned) who are mentioned in committee minutes.
Following an amendment to legislation, lobbyists attending a committee session must now also disclose the name of the person or body that they are representing in the committee session, and this information can now be found in the session minutes, e.g. https://oknesset.org/committee/meeting/13384/

This information should be added to Open Knesset committee data.
