< < | There were splinter meetings on provenance in Baltimore, Garching and Nara. No trace has been left about this. But it was opportunities to discover requirements from newcomers in the game. The same happened at EURO-VO meetings in the same period. | ||||||||||||||||||||

According to IVOA rules at that time a Data Model had to be exposed with an UML schema. In 2010 it was considered time to try to build one.

* Sao Paulo review (October 2012) | |||||||||||||||||||||

< < | In a dedicated splinter meeting at this interop an attempt was made to relaunch the effort. There was a lot of use cases summarized in the Introduction talk as well as a summary of the previous technological attempts. there were talks by Nikos from Marseille (caclulator), ArnoldRots and KristinRiebe, but unfortunatly they are lost. A the end of the meeting MarkusDemleitner concluded that the approach followed so far was defintly too ambitious and we had to start with revised ambitions and more stable technology. This started at the Heidelberg meeting in May 2013. | ||||||||||||||||||||

* Conclusion | |||||||||||||||||||||

< < | Why was all this so slow and eventually "failed". In FrancoisBonnarel opinion there was a sociological and a technical reason. The sociological one was that the Provenance task was nobody's priority task (including DM "permanents" like Mireille, Anita, Igor or myself) just because there was much more critical businness at the time. Things have changed now. The technical point was that ther was a lot of classes ato develop and many ways to describe the metatada. Probably moving to the W3C core architecture helped to structure the efforts | ||||||||||||||||||||

The sociological one was that the Provenance task was nobody's priority task (including DM "permanents" like Mireille, Anita, Igor or François) just because there was much more critical VO businness for them at the time. Things have changed now. The technical point on the other side was that there was a lot of classes to develop and many ways were possible to describe the metatada. Probably moving to the W3C core architecture helped to structure the efforts around a sound an stable core. | ||||||||||||||||||||
