1How to differentiatie GET queries with different parameters. If we dont have named parameters how best to know what is meant

Alternatives

  1. GET /anchorpoint/dataspace/{dataspace} versus /anchor-point/name/{dataspace}
  2. GET /anchorpoint?dataspace={dataspace} versus /anchor-point?name={dataspace}
  3. GET /dataspace/{dataspace-id}/anchorpoint versus /anchor-point/{name}
  4. GET /dataspace/{dataspace-id}/anchorpoint versus /anchor-point/name/{name}
  5. GET /dataspace/{dataspace-id}/anchorpoint versus /name/{name}/anchor-point

2Advance queries v Simple Queries (gets) for data fragments. Do we want/need differentiatie on UTL?
  1. GET /fragment/query/{xpath}
  2. GET/fragment/{xpath}  
  3. GET /query/{xpath}

Note . The xpath could be a full unambiguous xpath returning one object or it could be partial path using wildcards etc allowing for more advanced queries return 0 or more fragments (developed over many iterations)


3We have no modules sets!model files just arbitrarily group a few modules, is there a need to persist this grouping (We do have the concept of a dataspace as well)

model set

module (reference), given an anchor point 

Fragment persistence

11GET /anchor-point

Get the anchor point of a fragment given a fragments xpath

Fragment persistence

anchor-point
dataspace}/{name}/FileCreate
fragment given an anchor point
a (root) fragment for a given anchor point, the fragment can have children.
13PUT /fragment/{parent-fragment-id}/FileCreate a fragment given an ID relative to the parent
14GET /fragment/{dataspace}/{
