While the Beacon response should be restricted to aggregate data (yes/no, counts, frequencies …), the usage of the protocol could be greatly expanded by providing an access method to data elements matched by a Beacon query.
As part of the mid-term product strategy, the ELIXIR Beacon team is evaluating the use of a “handover” protocol, in which rich data content (e.g. variant data, phenotypic information, low-level sequencing results) can be provided from linked services, initiated through a Beacon query (and possibly additional steps like protocol selection, authentication…). A discussion of the topic can e.g. be found in the Beacon developer area on Github (issue #114).
As of 2018-11-13, the handover concept has become part of the ongoing code development.
