In the Virtual Observatory (VO), a registry helps users locate resources, such as data and services, in a distributed environment. A general framework for VO registries is now under development within the International Virtual Observatory Alliance (IVOA) Registry Working Group. We present a prototype of one component of this framework: the publishing registry. The publishing registry allows data providers to expose metadata descriptions of their resources to the VO environment. Searchable registries can harvest the metadata from many publishing registries and make them searchable by users. We have developed a prototype publishing registry that data providers can install at their sites to publish their resources. The descriptions are exposed using the Open Archive Initiative (OAI) Protocol for Metadata Harvesting. Automating the input of metadata into registries is critical when a provider wishes to describe many resources. We illustrate various strategies for such automation, both currently in use and planned for the future. We also describe how future versions of the registry can adapt automatically to evolving metadata schemas for describing resources.
