How do the current, last and next shortcuts behave?

For the purposes of the API, a season is assumed to begin when results become available for the first race of the season. This transition will be seen if the <season> field in URLs is set to "current".

In a similar way, the changeover point for the "last" and "next" round shortcuts occurs when a new set of race results become available. After the last race of a season the URL:

http://ergast.com/current/next/...

will refer to the first race of the following season.

Is there any restriction on how qualifiers can be combined?

A query can include any combination of the following qualifiers unless otherwise stated:

/circuits/<circuitId>
/constructors/<constructorId>
/drivers/<driverId>
/grid/<position>
/results/<position>
/fastest/<rank>
/status/<statusId>

For example:

/drivers/alonso/constructors/renault/results/1

The order of the qualifiers has no effect except that the last one determines the result type.

Season, Driver, Constructor and Standings queries can include the following qualifiers, subject to certain restrictions:

/constructorStandings/<position>
/driverStandings/<position>

The last qualifier in a query determines the type of data returned.

What happens if a round is not specified?

For Standings queries and queries which include a standings qualifier the round value defaults to the last round of each season (i.e. the final standings). Otherwise a query covers all rounds of a season.

What is the purpose of the attributes in the table elements?

All responses contain a table of some kind. The attributes of the table element define the scope of the table and reproduce the criteria specified in the original query. If a specific attribute is omitted the scope concerns all entities of that type e.g. if there is no driverId attribute the scope of the table is all drivers who match the specified criteria.

How soon after a race will data become available?

Usually in 3 – 6 hrs.
