	** The MTConnect Standard has progressed from an XML- and PDF-based normative to a SysML model, and now to an ontology layer on top of the information model. The transition from paper to a model-based approach has yielded significant advantages, but it has not resolved critical concerns regarding validation, trustworthiness, and usability. As the standard has matured, additional challenges have arisen that modeling languages such as SysML cannot address. With the increasing need for cross-domain information sharing and supplier agility, existing standards impede interoperability due to insufficient semantic representation and siloed viewpoints. These issues have become very apparent as we explore certain domains, such as capabilities, that cannot be addressed without an ontological approach.		** The MTConnect Standard has progressed from an XML- and PDF-based normative to a SysML model, and now to an ontology layer on top of the information model.

	== Discussion ==		== Discussion ==
			12:33:55 TS : If inconsistencies are found, how will the (text) standard be modified?

			12:35:44 John Sowa : OWL is a rinky dink disaster/
			* TS : John, yes. OWL is not ideal, but it’s ‘accepted’ and there is a lot of support for it.
			* John Sowa : Full first-order logic is the barest minimum for expressivity of any reasonable system.
			* John Sowa : And FOL has a very clean and simple mapping to and from English or any other natural language..
			* John Sowa : And FOL has an extremely large and powerful supply of powerful tools for EVERYTHING imaginable.
			* John Sowa : Tim Berners Lee in 2000 stated FOL as the barest minimum for representing the Semantic Web.
			* Ram D Sriram : I agree with John on FOL, but Todd's question of what to do with current OWL implementations needs to be addressed.

			12:35:56 Ram D Sriram : A related work from NIST can be found at: https://www.sciencedirect.com/science/article/pii/S001044851200022X

			12:42:33 Ram D Sriram : Another paper of interest is: https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=1458714

			12:48:52 Ram D Sriram : This paper describes how OntoSTEP was used in the FRENCH ANGEL project: Danjou, C., Le Duigou, J., & Eynard, B. (2016). Closed-loop manufacturing, a STEP-NC process for data feedback: A case study. Procedia CIRP, 41, 852–857. https://doi.org/10.1016/j.procir.2015.12.128 Cited by: 7
			* This paper was presented at the 48th CIRP Conference on Manufacturing Systems (Helena et al., 2022). It is a critical reference for the ANGEL project because it demonstrates how the STEP-NC (ISO 14649) standard can be used as a bidirectional data model to bridge the gap between CAM systems and CNC machines (Helena et al., 2022).
			* By utilizing OntoSTEP-NC, the researchers established a "data feedback" loop that allows manufacturing knowledge and real-world machine performance to be sent back to the design and programming stages, enabling more intelligent and automated process planning (Helena et al., 2022; Thomas et al., 2021).
			* Will Sobel : OntoSTEP was a translation from EXPRESS to OWL and didn’t fix any of the issues in the EXPRESS model. They also didn’t adhere to any higher level theory. STEP AP-242 has multiple identity and unity issues. This is why ED 5 had to move to a new UUID scheme when trying to have design to inspection connectivity.

			12:51:48 Jackie Csonka-Peeren : Let us not get caught by our own "ambiguity aversion"
			* TS : Please explain

			12:53:22 Yves KERARON (ISADEUS) : And keep the liberty of interpretation to the receiver.
			* Jim Logan ⎱Ontogenesis⎰ : Some would like to reduce the possible interpretations of representations in a model as things in the world.
			* Jackie Csonka-Peeren : 👍
			* Jackie Csonka-Peeren : yes, this makes sense at the 'local' level. Ambiguity in standards promotes wide adoption, which is considered beneficial

			12:53:48 Yves KERARON (ISADEUS) : in his concrete context FOL is the barest minimum ; what would be the maximum? Or the reasonable ?
			* Yes we will need extensions to FOL logic (Linear logic, …) and not a limited logic as OWL

			13:07:31 Yves KERARON (ISADEUS) : Thank you for the discussion
