DHP Aggregation - Integration method

The integration method can be applied every time new information, which is not aggregated from the repositories nor computed directly by OpenAIRE, should be added to the results of the graph.

The information integrated so far is:

  1. Article impact measures
    1. Bip!Finder scores
  2. Result Subjects
    1. Integration of Fields od Science and Techonology (FOS) classification in results subjects.

The method always consists in the creation of a new entity in the OpenAIRE format (OAF entity) containing only the id and the element in the OAF model that should be used to map the information we want to integrate.

The id is set by using a particular encoding of the given PID

unresolved:[pid]:[pidtype]

where

  1. unresolved is a constant value
  2. pid is the persistent id value, e.g. 10.5281/zenodo.4707307
  3. pidtype is the persistent id type, e.g. doi

Such entities are matched against those available in the graph using the result.instance.pid values.

This mechanism can be used to integrate enrichments produced as associated by a given PID. If a match will be found with one of the results already in the graph that said result will be enriched with the information present in the new OAF. All the objects for which a match is not found are discarded.
