Collecting provenance

Provenance metadata is generated by SPADE reporters. An arbitrary number of reporters can be added. The SPADE server integrates the provenance records coming from all of them.

To help a user start sending provenance information to SPADE with minimal effort, we have implemented a DSL reporter. It creates a named pipe in the filesystem, to which a user can send provenance information in a simple language.

It is also possible to report provenance information through a programming interface instead of the DSL reporter.

We provide additional reporters for collecting operating system level or filesystem level provenance on both Mac OS X and Linux.

To learn more about these reporters, see the submenu items on the left.

Note that the Reporter class is loaded by and runs as part of the SPADE server. Hence implementing such a class requires handling the inter-process communication with the source from which the provenance is being collected.
