It's originated in the OASIS Universal Business Language (OASIS-UBL) community where they were experiencing problems with spec compliance, interoperability, and low/slow technology adoption rates. UBL is a set of 90+ schemas defined for the most commonly used business documents used in commerce today. That was interesting. I wonder if this is combinable with my personal favorite, distributed public discovery services: https://www.linkedin.com/posts/andersrundgren_iso20022-messaging-api-activity-6958992983010484224-0sxX Live link: https://test.webpki.org/saturn-payeebank/ This will eventually be converted to CBOR to get away from canonicalization once and for all.

For example, this would be a stepping stone for enabling a layered approach to how verifiable credentials are defined, used, and exchanged - an opportunity to move away from a "one-size fits all" niche VCDM specification to a layered model that addresses the dual needs of: > a) the layering of simple, more generic models through to more complex niche credential specifications, as well as > b) an interoperability model that is simple, secure, efficient, and low-cost. > > Live Presentation: Case study of a semantic library underpinning the 4-corner model for document exchange 2022-11-08 > > https://www.linkedin.com/posts/gkholman_ken-holman-case-study-of-a-semantic-library-activity-7001714323223977985-IKbA > > Case study of a semantic library underpinning the four-corner model for document exchange > https://doi.org/10.1075/da.2022.holman.four-corner-model > Proceedings of Declarative Amsterdam 2022 (7 and 8 November 2022) > Available under the CC BY 4.0 license. > > > > Best regards, > > Michael Herman > > Web 7.0 > >
