[H—>O] Beacon Handover for Data Delivery

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.

Possible scenario for a Beacon-initiated "handover" data delivery, involving pre- or post- query authentication steps. Importantly, the identification of matching "rich" data elements (e.g. information about biosamples or individuals) happens internally, and only a data access handle is exposed to the Beacon ecosystem.
