Breaking Changes

• SIG agreed unanimously with the Linked Art community to rename E22 Man-Made Object to E22 Human-Made Object, thereby changing the class name in RDF, and thus the Linked Art API, and thus crom. This is an excellent change for the social good.

• SIG approved a subproperty of P2_has_type called P177_assigned_property_type, for use with E13 Attribute Assignment, and referring only to properties. This is a breaking change for the model, as we have previously used the (previously correct) P2_has_type for this. This makes it easier to distinguish between types-as-types, and types-as-properties.

EDIT: last commit renames it to the more intuitive assigned_property from the default. This came from updating documentation and looking at it in context.

• SIG approved the creation of P90a_has_lower_value_limit and P90b_has_upper_value_limit to fill the gap in the hole left by the deprecation of P83_had_at_least_duration and P84_had_at_most_duration in favor of the new P191_had_duration. This is a good change for consistency, and thereby ease of understanding.

PR adds/updates tests, vocab, model, data, utils functions for these changes.

Future Breaking Change Warnings

Members of the SIG present at Paris meeting unanimously agreed that E92 Spacetime Volume SHOULD NOT be a superclass of E4 Period and E18 Physical Thing. SIG process does not allow proposals to be ratified at the same meeting, and thus this will (hopefully) hit after the October SIG in Heraklion. Thus, if you have used P10 instead of P9, this will soon stop working. Probably this will not affect us at all.

The CRMSoc (social) extension will define a Payment class, that will replace linked art's internal payment class. This will be a breaking change at the RDF level (namespace change), but likely not the JSON. Timeframe is unknown but unlikely to be in the next 6 months.

Proposal to create a separate extension for ongoing states, be they social, mental or physical. This would replace linked art's internal Phase class, and likely change names but hopefully little disturbance to the structure. Timeframe is unknown but unlikely to be in the next 12 months.

Rob, Beyond the use of the ManMadeObject, are you aware of these breaking changes being used in the Provenance Index mapping scripts?

thanks

I don't believe that the other changes affect the PIR work at the moment. The P177 one will in the future, but then it will be already changed :)
