Finally getting some glimmers of understanding using rdflib. Use of predictate_objects method to get all the objects for a given subject.

recurse.py developed to walk the graph and get all the relevant information required. Integrate that into the acLearningArea.py class in 005-exploring-oz-dev-log

What do I need to do#

  • Simple test - list all content descriptions and some properties

  • Exploration - understand the parent/child structure of all components

    e.g. content descriptions belong to?

Exploration - parent/child structure#

Manual inspection of MAT.rdf#

statementNotation ==root - copyright statement etc (19679b09-cfba-4cd0-a02e-366ace2f3d83)

  • statementNotation "LA" title "Learning Areas" (c357c885-ff1c-465e-a521-81339382c9a5)

    One appears to be holder of learning areas - statementNotation "Learning Area" title "Mathematics" (5261cb07-bce5-435d-a979-b161a432016d)

Automate inspection#

Recursive function to walk through the tree

getRootId(g) - working#

Given a graph get the subjectId for predicate statementNotation and object root. Check that only one should be returned.

recurseOzCurriculum(g, subjectId, depth=0)#

Given the graph and the rootId (known as subjectId within the function as it recurses down), recurse through the tree, keeping track of the depth.

  • Get all the predicates and objects that have subjectId as the subject.
  • Split all the predicates/objects (pos) into either children or information.

  • display information about the node (not the children)

  • only for the predicates: statmentNotation, statementLabel, title

  • loop through all the node children and recurse from there

Revealing#

Some nodes are not included, e.g. - statementLabel = Achievement Standard - Level Descriptions are included as subject dcterms:description for statementLabel Level

root - LA/Learning Areas - MAT/Mathematics - MATMAT/Mathematics - MATMATFY/Foundation Year - MATMATFY_1NUM/Number - AC9MFN01/ - AC9MFN01_E1/ - more elaborations - more content descriptors

Exploration of where Achievement Standards fit#

Related statementLabel predicates

21ec0e04-b342-4210-8dd9-7f98c13bb7d3 is found in

  • predicate hasLevel for statmentLabel Level - same subject as the description i.e. year level

hasLevel (http://purl.org/ASN/schema/core/hasLevel) is defined as "resource description of a level of performance based on RubricCriterion"

  • Content Descriptions and Year Levels have them - need to add them for recursion
