Homogeneous universal metric spaces are constructed in the Jónsson class of metric spaces starting from finite metric spaces over the rationals and then completing the construction over the reals; the main theorem deals with the finite homgeneity property established by Urysohn for his famous universal metric space: we show that this can be extended to totally bounded metric spaces, thereby extending a prior result of Joiner (1971) who already extended this property to Cauchy sequences.Homogene universelle metrische Räume werden in der Jónsson-Klasse von metrischen Räumen konstruiert, ausgehend von endlichen metrischen Räumen über den rationalen Zahlen und dann über den reellen Zahlen vervollständigt.
