This probably would be a good place to explain why the top-level schema changed between versions 8.0.0-beta.5 and 8.0.0.
Before the release, we did an intensive review with three aims in mind:
Results:
The review took longer than anticipated and ended up delaying the release of HED-3G to the beginning of August.
The need to be compatible with a future ontology (an BFO-based OBO Foundry ontology, to be specific) triggered a top level reorganization. The main difficulty was that OBO has some requirements about relations, which were not satisfied in 8.0.0-beta. We ended up changing the top-level (
Agent-property
,Data-Property
,Task-property
, andAttribute
) to (Property
, andRelation
).Note: As long as annotators use the recommended short-form, moving terms around doesn't affect the annotation, so this isn't as draconian as it might seem.
There were some problematic individual terms that changed. For example,
Left-side
has becomeLeft-side-of
to make it clearly aRelation
.Another problematic tag was
Visual
which becameVisual-presentation
. In generalSensory
has been separated into subcategoriesSensory-attribute
andSensory-presentation
underSensory-property
. This was probably the change that will affect previously annotated data the most, but it cleaned up a lot of clarity issues.Beta Was this translation helpful? Give feedback.
