Not online, but you can look for: - Christuslob. Das Stundengebet in der Gemeinschaft (Herder, 1992) ISBN 978-3-451-22517-4 - Antiphonale zum Stundengebet (Herder, 2010) ISBN 978-3-451-20020-5
1. Quite crappy (lack of support for browsing to the future and past; seems to ignore some feasts), but official http://stundenbuch.katholisch.de/ (this is what @joerg suggests above - I hadn't checked before I wrote this)
If music is what you are looking for, it should be noted that Christuslob, suggested by @smvanroode, is originally a pre-Vatican 2 vernacular little office. It has shorter psalter and drastically reduced both Proper of Seasons and Proper of Saints.
