 \subsection{Previous efforts}
+The provenance concept was early introduced by the IVOA within the scope of the Observation Data Model (ref1 : IVOA note 2005) as a class  describing where the data are coming from. A full observation data model dedicated to the specific spectral data was then designed (Ref2 : spectral data model) as well as a fully generic characterisation data model of the measureemnt axes of the data (ref3: characterisation data model) while the progress on the provenance data model were slowing down.
+IVOA DM WG first gathered various use cases coming from different communities of observational  astronomy (optical,  radio, Xray, interferometry). Common motivations for a provenance tracing of the history included : quality assesment, discovery of dataset progenitors and access to metadata necessary for reprocessing. Provenance datamodel was then designed as the combination of Data processing, Observing Configuration and Observation ambiant conditions datamodel classes. 
+The Processing class was embedding a sequence of processing stages which were hooking specific ad hoc details and links to input and output datasets, as well as processing step description. 
+Despite the attempts of UML description of the model and writing of xml serialization examples the IVOA effort failed to provide a workable solution:  the scope was probably too ambitious and the technical background too instable. A compilation of these early developments can be found on the IVOA site (ref4). From 2013 onwards IVOA concentrated on use cases related to processing description and decided to design the model  by extending the basic W3C provenance basic structure,as described in the current specification. 
 Outside of the astronomical community, the Provenance Challenge series (2006 -- 2010), a community effort to achieve inter-operability between different representations of provenance in scientific workflows, resulted in the Open Provenance Model (\cite{moreau2010}). 
 Later, the W3C Provenance Working Group was founded and released the W3C Provenance Data Model as Recommendation in 2013 (\cite{std:W3CProvDM}).
