– | unordered and ordered collections are represented by two separate class constructs, Bag and List respectively | + | unordered and ordered collections are represented by the same class construct, Aggregation |
+ | item property names are easy to understand (e.g., index, itemContent, nextItem) | – | item property names are cryptic (e.g., proxyFor, proxyIn, next) |
– | order is determined by an item property pointing to the next item, i.e., nextItem | – | order is determined by an item property pointing to the next item, i.e., next |
– | URI for the item is not associated with the collection class (e.g., List, Bag). | + | URI for the item is associated with the collection class (i.e., Aggregation) via of the aggregates property. |
+ | URI for the item is associated with the item class (i.e., Item) via the itemContent property. | + | URI for the item is associated with the item class (i.e., Proxy) via the proxyFor property. |

XXX
QUESTIONS:
- Should Virtual Collection's type be a subclass of co:List instead of a co:List?
- If so, what is the type? Consensus: Subclass of co:List Ontology to be defined by ontology group.
- Is it LD4L specific? Consensus: YES to be defined by ontology group.
- How is LD4L defining new types? Naming convention, namespace, etc.? Final definitions by ontology group.
- For now, use namespace=LD4L in Ruby with link <http://ld4l.org/ontology/... – to be defined by ontology group
- Class name=ld4l:VirtualCollection
- type URI=<http://ld4l.org/ontology/VirtualCollection>
- instance URI=<http://localhost:3000/individual/vc123> –
- what ever I want for now
- suggest use of individual in URI meaning an instance of a class (used by VIVO too)
- id starts with alpha because syntax something:vc123 – cannot have number directly after :
