What is a registry?
A registry functions as a sort of yellow pages, or high-level directory, of astronomical
catalogs, data archives, data-providing organizations, and computational
services . You can search the registry to find data of interest, review the
data source descriptions, and in many cases make direct position-based data
requests.
What is a resource?
A resource is a general
term referring to a VO (Virtual Observatory) element that can be described in terms of who curates or
maintains it and which can be given a name and a unique identifier. Just about
anything can be a resource: it can be an abstract idea, such as sky coverage or
an instrumental setup, or it can be fairly concrete, like an organization or a
data collection. This definition is consistent with its use in the general Web
community as “anything that has an identity” (Berners-Lee 1998, IETF RFC2396).
We expand on this definition by saying that it is also describable.
There are several types of resources published in the VO registries: standard VO data services (SIAP, Cone, SSAP, and
SkyNodes, data collections, organizations, other registries are even considered resources.
