An example method of loading classes from a content repository includes storing a set of files in a content repository. The set of files includes a representation of a set of classes. The method also includes extracting first metadata that describes the set of classes and storing the first metadata in a content repository. The method further includes receiving a request including second metadata corresponding to one or more classes of the set of classes. The request is from a repository-class loader executable in a node. The method also includes selecting, based on the second metadata, a class of the set of classes. The method further includes sending the selected class to the repository-class loader for loading into the node.
