It was recommended that globally unique values for
identifier
should be specified way back with #69 and the guidance was updated to make this a recommendation (using a URL) with the update to v1.1, but it was not a strict requirement. After several years of this metadata making its way across the internet ecosystem it's now more clear than ever that this needs to transition to a hard requirement. The case for this was already made pretty sufficiently within #69. This issue is meant to lead both to final guidance on that as a hard requirement, but also to more immediately develop a migration pathway to transition current non-global values foridentifier
to proper URLs.One migration option may be to define a convention where a unique ID for each agency is paired with the non-global
identifier
for the dataset and then have that appended to the end of a URL, potentially using a similar approach as W3ID to help maintain persistence.For instance, if GSA has a metadata entry with a non global identifier like
GSA-2016-01-22-01
then that could be represented as a more global URI likedcat-us:federal/gsa/GSA-2016-01-22-01
but ultimately it would appended on to a URL for a final value of something likehttps://id.data.gov/dcat-us/federal/gsa/GSA-2016-01-22-01
. We'd also need to consider URL encoding as part of this transformation since there aren't any restrictions on the current values.The text was updated successfully, but these errors were encountered:
