ESRF Ontology - inclusion of instrument - strategy
To be validated and included in documentation and our future guidelines. @koumouts @denolf
Discussion 2024/04/03 WDB, GKO, RDU :
- PaNET ontology does not include instruments
- ESRF ontology is a branch of PaNET ontology (.owl file)
- ESRF may add new terms not in PaNET ontology. Then propose them to PaNET "consortium"
Very important : "to be triple" validated by Giannis and Wout : ESRF ontology should not include "instruments" :
- An instrument is a set of hardware, detectors etc... and settings
- Instrument may be moved from one Insertion Device (ID) or Bending Magnet (BM) on ESRF ring. We use for example ID22 to describe the instrument. It is a very confusing metonymy used by almost everybody at ESRF.
- we can conclude : Instrument at ESRF don't have names, only insertion devices have.
- Simply adding ID22 (insertion device name) to ontology and link it to techniques is not possible. (if instrument moves, links become not relevant ex: "Andy Fitch instrument doing hrpd" moved from bm16 to id31 (in 2003) to id22 (in 2014 ).
- After discussion adding start date, end date in ontology may seem but is not a good solution as well.
- We think it is simply better to have technique linked to dataset and Insertion Device.
- This way, we will get knowledge of instrument organisation on the ring from the dataset and not from the ontology. A kind of "bottom up" strategy.
- Wout said :"we need single point of truth". Renaud : "when the first dataset comes from an ID with a new technique. we know a major instrument change happened on the ring"
Final thoughts...
- Renaud : for instruments : we only have vague knowledge of set of hardware, detectors that are constantly evolving. There is no culture at ESRF for official "names" or persistent ids for instruments.
"The word Renaissance was used for the first time in the 16th century by Giorgio Vasari, founding father of modern art history, in the famous anthology Lives of the Most Famous Painters, Sculptors and Architects, to refer to the artistic trend which had emerged in Italy two centuries earlier".

This does not stop us to track ESRF instruments history. It is done here : https://confluence.esrf.fr/x/ipUGAw (ESRF ontology is just not the accurate place to do that )
