A method of and a program for providing coherence between instances of data objects residing on distributed nodes of a non-memory-coupled network. To provide a method of and a program for providing coherence in accordance with the features set forth in the opening part of this specification, which allows coherence between, in principle, any data objects or instances of data objects, in that respect is substantially freely scalable and also does not require a central memory or server for the data objects. In accordance with embodiments of the invention, for each instance of a data object that is processed by a node, platform-independent unique metadata are generated and by means of the metadata and a coherence protocol which operates on that metadata, the metadata and thus the data objects are kept coherent.
