Data and services

[Tony Linde]

Can I suggest some naming rules (bit rich since I'm not an astronomer) to
avoid confusion. 


Everything referred to by a registry entry is a resource, uniquely and
globally identified by a ResourceId.

A service is anything which is invocable, ie is a web service with callable
methods.

A data collection is any set of data which can be queried.

A sky service is a service which provides access to a data collection.

A dataset is any addressable part of a data collection. Access to the
dataset is via the sky service of the data collection.


How does that sound?

Cheers,
Tony.
