The SuggestingAdapter is an extension to rdflite that can recommand additional predicates for a given resource, based on usage statistics in the whole dataset. E.g. given a dataset with FOAF data, one can ask a suggestion for a person and get a recommendation for this person to also use foaf:birthday. You can use this adapter in any collaborative editing setting: it leads the community to converge on terminology (everybody will use the same foaf:birthday to define somebody’s birthday).
