- Alex made some progress on the demonstrator. Alex will get the
demonstrator nearly done in the next month
- Alternative implementation from Frederik, can share some code with
Alex implementation
- Both implementations will have different backends (Redis, Triple Store)
-
- maxDepth:
- default will be 0
- maxDepth: will be property on the service level
- appendsToEnd: is the collection a stack or a queue
- it is possible to add an element at any place in the list (adding in
the middle)
- item matching: differentiation between data property and functions on them
- roles: makes sense to have, but difficult to set a default
- properties are making up models like set, array etc.
- left over for the next session: Future extensions
- first draft of a text should be available at next plenary

Thank you, Thomas! Adding two more bullet points:
- We figured out that maxDepth is actually relevant to both Service and Collection:
- In a service it describes constraints on the traversal operations
- A default here might be 0 => no server-side traversal
- In a collection it describes constraints on the data structure
- A default value here might be -1 => no limits on recursiveness
- In discussing the ‘role’ mapping there were different opinions about its generality and complexity:
- we may want to leave out the default value
- thus role becomes a simple and general tagging mechanism
- implementation requirements would be similar to index/dateAdded
- things like default values and controlled vocabulary would be left to the client
Next meeting is February 14th. See you there,
Frederik
