I assumed to find data type URIs for EDTF values to be used when <a> dc:date "2023?"^^edtf:level1 .
<b> dc:date "‘Y-17E7"^^edtf:level2 .Am I missing something? |

It looks like the official datatype definitions are here: http://id.loc.gov/datatypes/EDTFScheme They have three scheme members defined:
No substantial differences between those definitions. Interestingly, they all define their subjects as datatypes, classes, AND individuals. Maybe there's no level3 because it hasn't been formally adopted, see comments like citation-style-language/schema#421 (comment) |

Hello! There is also a 4th datatype defined as the union of the three levels: http://id.loc.gov/datatypes/edtf/EDTF The range of I didn’t bother explicitly putting datatypes on the EDTF literals in the examples because I was primarily interested in OWL inferencing over OWL-Time constructs generated from EDTF strings, and OWL tools basically ignore datatypes. But you are right that it would be more correct to do so, and might make the data easier to work with when using RDF-focused (rather than OWL-focused) tools. I should also add that this repo has no connection to LoC or ISO, no official status whatsoever, just an experiment in modeling and inferencing over EDTF expressions. |
