We have moved to a new Doc portal hosted on the same URL. Because of the volume (number of versions, number of pages etc), we could not put in place a redirection from Confluence but all the content is there and can be searched from the home page: https://help.talend.com/
We're fixing some links and redirection at the moment. As soon as it's done, I'll communicate to the Community.
You should be able to find the tXMLMap though: https://help.talend.com/#/reader/wDRBNUuxk629sNcI0dNYaA/yZJFgdpcM_OEmIjL7ZnBng Let me know if you couldn't find it. Or if this isn't what you were looking for.
