The discussion was a high-level overview of the specification as we near v0.1.0. Daniel Bucher discussed future ZKP and other format support. We encourage all to attend and join DIF and contribute on the GitHub. We intend the specification to be used by a wide number of companies on different tech stacks and we have taken care to support as many use cases as possible.


Kim Duffy raised a point about considering prior art and hesitation around “re-inventing” generic selection language. Daniel responded stating we heavily leverage JSON Path, and JSON Schema, and have looked at a number of open source alternatives, none which quite met the case. Gabe responded that we are open to improvements, suggestions, and change if there are better alternatives.
