public class MCREnricher
extends Object

Enriches a given MODS publication by retrieving publication data from external data sources and merging that data into the existing data. There may be different configurations for the enrichment process. Each configuration has a unique ID and determines the selection of data sources to query and the order and priority of merging. MCR.MODS.EnrichmentResolver.DataSources.[ConfigID]=[DataSourceID] [DataSourceID] [DataSourceID]... e.g. MCR.MODS.EnrichmentResolver.DataSources.import=(Scopus PubMed IEEE CrossRef DataCite) OADOI (LOBID GBV SWB) ZDB All data sources that support one of the identifiers present in the publication are queried. Depending on the configuration properties MCR.MODS.EnrichmentResolver.DefaultStopOnFirstResult=true|false and MCR.MODS.EnrichmentResolver.DataSource.[ID].StopOnFirstResult=true|false the data source will stop trying to resolve publication data after the first successful call with a given identifier and skip others, or will try to retrieve data for all given identifiers. Should a data source return new, additional identifiers, other data sources that support these identifiers will be tried again. The enrichment takes place on each publication level, that means also the host (e.g. journal or book the article is published in) and series level is enriched with external data. The order of the data source IDs in configuration determines the order of merging the publication data. If some data sources are grouped using braces, merging is skipped after the first successful data source. For example, when MCR.MODS.EnrichmentResolver.DataSources.sample=A (B C) D all four data sources are queried until all returned data or all identifiers have been tried. Afterwards, the data returned from A is merged into the original data. Next, if B returned data, the data of B is merged and the data of C will be ignored. If B did not return data and C returned data, the data of C is merged. At the end, the data of D is merged. So building groups of data sources with braces can be used to express data source priority.
