+Then the final schema in `linkml_activitypub/activitypub.yaml`:
+- Reorder to match ActivityStreams 
+- Ensure correct
+  - inheritance
+  - `multivalued`
+- Prune extra properties and classes to match those in [ActivityStreams2](https://www.w3.org/TR/activitystreams-vocabulary/) normative definition
+  - Then re-add the ones that declare a class in their domain, even if the class doesn't list that property in its definition
+  - Except for those types that seem to be metaclasses:
+    - `attributedTo` (-> `actor`)
+- Added LinkML properties (where needed):
+  - Classes
+    - `disjoint_with`
+    - `see_also` when references given
+  - Properties
+    - `description`
+    - `domain`
+    - `range`
+    - `minumum_value`
+    - `maximum_value`
+- Added missing slots
+  - `closed`
+  - `startIndex`
+- Handle special property cases
+  - `items` is marked as `list_elements_ordered: true` on `OrderedCollection` and false on `Collection`
+- Made types
+  - anyURI as `xsd:anyURI`, did not try and find a validator pattern. The spec alternatingly uses its own anyURI prop and `xsd:anyURI`
+- Made enums
+  - `unitEnum` - for `unit`
+- Copied Notes to class `description` rather than `comments`
+- Added schema prefixes:
+  - `schema`: https://schema.org/ - for specifying IETF BCP 47 language codes

+- `OrderedCollectionPage` is not a subclass of, and doesn't mix in `CollectionPage` since it would then have an ambiguous
+  class definition, since `OrderedCollection` inherits from `Collection` but asserts that the `list_items_ordered` slot is `true`
+  rather than `false`. Instead, the slots from `CollectionPage` are just duplicated.
+  - Accordingly, the domain and range of slots that include `CollectionPage` also include `OrderedCollectionPage
