VODataService xs vs 0.1 Version 0.8 An extension to the core resource metadata (VOResource) for describing data collections and services. A logical grouping of data which, in general, is composed of one or more accessible datasets. (A dataset is a collection of digitally-encoded data with a that is normally accessible as a single unit, e.g. a file.) Extent of the content of the resource over space, time, and frequency. the spatial coverage of a resource Note: type not yet defined the temporal coverage of a resource Note: type not yet defined the spectral coverage of a resource Note: type not yet defined the resolution of the resource contents Note: type not yet defined a description about how a data collection may be accessed The physical or digital manifestation of the information supported by a resource. MIME types should be used for network-retrievable, digital data.

This is a base type for defining specific kinds of service descriptions. Specifically, a textual description of the interface. This is typically only used when a structured description is not available or supported for this particular type of interface. a specific description of the context and capabilities of a service. This is a base type for defining specific kinds of service capability descriptions, each with its own special mark-up schema. An identifier for a registered standard. A URL that points to a human-readable document that describes the standard upon which a resource is based. This is different from the Service's ReferenceURL, which should describe the specific implementation of the standard service. A service for accessing astronomical data
