This schema defines common types that can be re-used. XML elements of this type are simple strings, but in cases where their values have been inferred by Openaire inference algorithms, the elements features some attributes describing the inference algorithm. This way it is easy to understand if a value comes from the originally imported data or if it has been added later for enrichment. XML elements of this type are simple booleans, but in cases where their values have been inferred by Openaire inference algorithms, the elements features some attributes describing the inference algorithm. This way it is easy to understand if a value comes from the originally imported data or if it has been added later for enrichment. True if this information has been inferred by the automatic inference algorithms run by OpenAIRE. Which algorithm inferred the current property. Value of trust of this information in the range [0,1]. More the value, more trustworthy is the information. Relationships to other entities. Tells if the related record is about a publication or a dataset. The similarity degree expressed in the range (0,1].
