  title     = {Recording Provenance in Service-Oriented Architectures}, 
  abstract   = {Provenance is the documentation of process for some result. This report addresses provenance recording in Service-Oriented Architectures, specifically for Grids and Web Services. The document begins by motivating the need for provenance recording. It then presents background information for Service-Oriented Architectures, Grids, Web Services and provenance software. Given this background, an architecture and protocol for recording provenance are presented along with an implementation of a provenance service. Finally, a direction for future work is outlined.} ,
