A trace whose obsels are computed according to a Method, either from a number of source traces (transformed trace), or from external information (automatically collected trace). Although its obsel collection may be stored for performance issues, it can be assumed to be computed dynamically and always up-to-date w.r.t. the sources.
A computed trace is created by a POST query to a Base. It must have the following properties:
- http://liris.cnrs.fr/silex/2009/ktbs#contains linking from the Base
It can optionally have the following properties:
In addition to the query-string parameters accepted by any trace,
computed traces allow for the parameter
to control the computation process.
Recognized values are:
default(which is the default value!)
- will refresh the trace only if needed (i.e. if its method, its parameters or its sources have changed).
nowill prevent any re-computation.
forcewill force the re-computation of the trace, even if nothing has changed.
recursivewill recursively force the re-computation of all the sources of the trace, then of the trace itself.
