beaconHandovers

Set of handovers to be added in one section the response.

Array<object>

A handover is a typed link for attaching actionable links to results, non purely informational, requests. The goal of the handovers is to list the different actions available, e.g.:

  • a link to a request access page * linking to a file for download, e.g. a VCF file Another common scenario is to provide a fast summary response (e.g. BeconCountResponse) and to provide access to different endpoints for the entities matched by the query using temporary access tokens in the handover URLs.

info

Placeholder to allow the Beacon to return any additional information that is necessary or could be of interest in relation to the query or the entry returned. It is recommended to encapsulate additional informations in this attribute instead of directly adding attributes at the same level than the others in order to avoid collision in the names of attributes in future versions of the specification.

referenceName

Reference sequence id for genomic reference sequence in which variant coordinates are given, e.g. “refseq:NC_000009.12” for human chromosome 9 in the GRCh38 assembly. The use of the assembly specific RefSeqId is recommended although alternatively names, synonymous or aliases e.g. “chr9” could be used in conjunction with an Assembly parameter.

start

Precise or fuzzy start coordinate position(s), allele locus (0-based, inclusive). * start only:

  • for single positions, e.g. the start of a specified sequence alteration where the size is given through the specified alternateBases
  • typical use are queries for SNV and small InDels
  • the use of start without an end parameter requires the use of alternateBases
  • start and end:
    • for searching any variant falling fully or partially within the range between start and end (a.k.a. “range query”)
    • additional use of variantType OR alternateBases can limit the scope of the query
    • by convention, partial overlaps of variants with the indicated genomic range are accepted; for specific overlap requirements the 4-parameter “Bracket Queries” should be employed
  • 2 values in both start and end for constructing a “Bracket Query”:
    • can be used to match any contiguous genomic interval, e.g. for querying imprecise positions
    • identifies all structural variants starting between start[0] and start[1], and ending between end[0] <-> end[1]
    • single or double sided precise matches can be achieved by setting start[1]=start[0]+1 and end[1]=end[0]+1
Array<integer>

variantMaxLength
  • Maximum length in bases of a genomic variant. * This is an optional parameter without prescribed use. While a length is commonly available for structural variants such as copy number variations, it is recommended that length based queries should also be supported for variants with indicated referenceBases and alternateBases, to enable length-specific wildcard queries.

variantMinLength
  • Minimum length in bases of a genomic variant * This is an optional parameter without prescribed use. While a length is commonly available for structural variants such as copy number variations, it is recommended that length based queries should also be supported for variants with indicated referenceBases and alternateBases, to enable length-specific wildcard queries.
integer format: int64
variantType

The variantType is used to query variants which are not defined through a sequence of one or more bases using the alternateBases parameter. Examples here are e.g. structural variants: * DUP

  • increased allelic count of material from the genomic region between start and end positions
  • no assumption about the placement of the additional sequences is being made (i.e. no in situ requirement as tandem duplications)
  • DEL: deletion of sequence following start The Beacon model is not prescriptive with regard to the values allowed for variantType with use of extended types (such as from EFO:0030063) being possible. However, a support for the basic CNV types above - where represented in the data - is recommended. Either alternateBases or variantType is required, with the exception of range queries (single start and end parameters).

requestedGranularity
required

Level of detail of the response:

  • boolean: returns true/false’ responses * count: adds the total number of positive results found * aggregated: returns summary, aggregated or distribution like responses * record: returns details for every row. In cases where a Beacon prefers to return records with fewer than allattributes, different strategies have to be considered w/o adding them to the current design, e.g.:
    • keeping non-mandatory attributes empty
    • Beacon to provide a minimal record definition
string
default: boolean
Allowed values: boolean count aggregated record
testMode

Used for indicating that a request or response is done in a test context e.g. for compliance testing i.e. to evaluate the acceptance/understanding of a request and the structure of the returned response by the Beacon instance. A TRUE testMode parameter DOES NOT require that the Beacon instance is a test instance, but that this specific request-response cycle is a testing one. When true the Beacon instance MUST respond the request but it SHOULD use virtual or non-sensitive data. Here, what is being evaluated is the acceptance/understanding of a request and the structure of the returned response by the Beacon instance.
