API Estimates - Server, Client, Ingest

Server

• Object operations
  • (2 md B ) Startup project

  • (1 md B ) newObject(template) => pid Given a template, create a new object, return the PID

  • (0.25 md C ) deleteObject(pid) Given a PID, mark the object as deleted (note: object may only be undeleted by direct access to Fedora) (uncertain how easy it will be to use lower systems for the operation)

  • (0.25 md C ) markPublishedObject(pid) Given a PID, mark the object as published. Will fail if object does not validate. (uncertain how easy it will be to use lower systems for the operation)

  • (0.25 md C ) markInProgressObject(pid) Given a PID, mark the object as in progress. (uncertain how easy it will be to use lower systems for the operation)

  • (0.5 md C ) listDatastreamsObject(pid) => listOfDatastreams Given a PID, list datastream names in object. (uncertain how easy it will be to use lower systems for the operation)

  • (0.5 md B ) get pid of object that is main object for view of given name in which object of given name2 resides.

  • (2 md B ) ?addSubItem(pid, viewName, template) Given an object, a named view, and a template, create a new object for that template, then add relation between old and new object in the view. Will fail if there is no allwed relation in the view between the object and the template.

• Structural operations - For adding new view-external relations

  • (0.5 md B ) ?getAllowedRelations(pid) => listOfNamesAndCMS Given a pid, return possible relations that could be added, and the content models allowed as object for those relations.

  • (0.25 md B ) ?listObjectsWithContentModel(pid) Given a content model pid, list all objects that subscribe to that content model.

• Structural operations - For content model driven behaviour

  • (1 md B ) ?getContentModel(pid) => compoundContentModel (combined for its different content models) for this object

TOTAL PART 2: 26 md

Probably several of the small ones can be done in one go, so development time may become shorter. On the other hand, once we start coding, me may discover that more methods are needed. (Maybe 10 to 40 percent more methods)

TOTAL PART 2 WORST-CASE: 28 - 36 md (including 10 - 40 % extra)

TOTAL (PARTS 1 AND 2) : 38 md (WORST CASE: 40 - 48 md)
