The class/property search[edit]
The class/property search is done by traversing upward the hierarchy, trying to find all entities that branch off to a message. On all branches a penalty is given, and all branches that drops below a certain level is pruned.
As there can be several claims, and there can also be several starting points for the upward travel of the hierarchy. The starting point is given weight according to the rank, so a preferred statement would weight somewhat more heavy than a normal statement. Several preferred statements might add up to make a distant class with a plan the overall winner. Deprecated statements will not be traversed.
It is probably better to make a breath-first search, and prioritize those with highest weight before those with lower weight.
Content determination[edit]
The actual data is coming from statements in ordinary items, that is the statements about the topic described in the Wikipedia articles. Such items have statements, and those use properties (predicates) that themselves have statements pointing to one or more messages.
The possible messages are collected by an upward search in the hierarchy, trying to find all properties that branch off to a message.
At least one message must exist for the statement to be considered for inclusion. Which one to use must be considered during optimization of the content generation.

The generated structure will have pointers to the actual data.
Document structuring[edit]
The actual data is coming from ordinary items, that is those that represents articles in Wikipedia. Such items has an instance of, and that class (resource) has possibly statements pointing to one or more plans.
The possible plans are collected by an upward search in the hierarchy, trying to find all items that branch off to a plan.
At least one of the plans must be a document plan. This will be used to build the first iteration of the document, that is the article, for the items class. If multiple is found a tie-break will be done on the weight for the plans, and the one with highest weight is used.
All other document plans pointed to by the found classes are then stripped for the title and then merged to build an overall plan.
