In the context of Europeana, an aggregator is an organisation that gathers material from individual organisations, standardises formats and metadata, channeling them into Europeana according to Europeana guidelines and procedures. Aggregators also support content providers with administration, operations and training. Types of aggregators can be: country aggregators (e.g. the Italian national aggregator Cultura Italia), project aggregator (e.g. Linked Heritage Project Aggregator), independent organisations (with no Ministry or other mandate). Even individuals are invited to collaborate to the project providing historical documentation (e.g. citizens wishing to contribute to Europeana special collections, i.e. World War One Family History). Europeana encourages the contribution of aggregators that fit the needs of different countries, domains and users.
