There are some capabilities which are strongly recommended for services to support even
though they are optional. Support for $top and $skip is a good example as
supporting these query options helps with performance of a service and are essential. Such
capabilities are assumed to be default capabilities of an OData service even in
the case that a capabilities annotation doesn’t exist. Capabilities annotations are
mainly expected to be used to explicitly specify that a service doesn’t support such
capabilities. Capabilities annotations can as well be used to declaratively
specify the support of such capabilities.

On the other hand, there are some capabilities that a service may choose to support or
not support and in varying degrees. $filter and $orderby are such good examples.
This vocabulary aims to define terms to specify support or no support for such
capabilities.

A service is assumed to support by default the following capabilities even though an
annotation doesn’t exist:
- Countability ($count)
- Client pageability ($top, $skip)
- Expandability ($expand)
- Indexability by key
- Batch support ($batch)
- Navigability of navigation properties

A service is expected to support the following capabilities. If not supported, the
service is expected to call out the restrictions using annotations:
- Filterability ($filter)
- Sortability ($orderby)
- Queryability of top level entity sets
- Query functions

A client cannot assume that a service supports certain capabilities. A client can try, but
it needs to be prepared to handle an error in case the following capabilities are not
supported:
- Insertability
- Updatability
- Deletability
