create-graph clj/s

(create-graph profile)

(create-graph profile extra-profiles)

Create a graph of Pattern relations from profile and possibly extra-profiles that can then be used in validation. Relations can include those between Patterns and Statement Templates. If extra-profiles is provided, those profiles are traversed in order to add Patterns and Templates that are connected to the nodes of the main Profile's Pattern graph.

get-edges clj/s

(get-edges pgraph)

Return a sequence of edges in the form of maps, with the following keys:

• src: source node ID value
• dest: destination node ID value
• src-primary: true if the source node is a primary pattern, false otherwise
• src-indegree: how many other Patterns reference this node
• src-outdegree: how mahy Patterns or Templates this node references
• dest-type: 'type' property of destination node (Pattern or StatementTemplate)
• dest-property: the regex property of the destination node (sequence, alternates, etc.); nil if the destination is a Template
• type: the regex property of this edge (sequence, alternates, etc.)

get-external-iris clj/s

(get-external-iris profile)

Return the external IRIs from the Patterns of profile.

valid-edge? clj/s multimethod

validate-pattern-edges clj/s

(validate-pattern-edges pgraph)

Given the Pattern graph pgraph, return spec error data if the graph edges are invalid according to the xAPI Profile spec, or nil otherwise.

validate-pattern-tree clj/s

(validate-pattern-tree pgraph)

Given the Pattern graph pgraph, return spec error data if pgraph has non-singleton strongly connected components (indicating that a cycle was detected and pgraph is not a tree), nil otherwise.
