The Beacon v2 protocol uses a REST path structure for consistant data access.
The Beacon+ implementation - developed oin the bycon project
implements an expanding set of those Beacon v2 paths for the Progenetix
resource.

This page lists changes for the Beacon+ implementation of the “Beacon” genomics API.
As one of the drivers of the Beacon protocol and to drive the Beacon v2 protocol process we have now started the documentation of Beacon v2 endpoints which are supported in Progenetix as part of the implementations-v2 project:

The bycon environment provides a number of data services which make use of resources in the Progenetix environment. Please refer to their specific documentation.
Note: As of 2021-04-07 there are some changes - typical Beacon endpoints such as biosamples have been moved to the /beacon/__service-name__ path:
services.py and URL MappingThe service URL format progenetix.org/services/__service-name__?parameter=value
is a shorthand for progenetix.org/cgi-bin/bycon/services/__service-name__.py?parameter=value.

The bycon project provides a combination of a Beacon-protocol based API with additional API services, used as backend and middleware for the Progenetix resource.
bycon has been developed to support Beacon protocol development following earlier implementations of Beacon+ (“beaconPlus”) with now deprected Perl libraries. The work tightly integrates with the ELIXIR Beacon project.

Wherever possible, data annotation in Progenetix uses {S}[B] OntologyClass
objects for categorical values, with CURIEs as id values. So far, the
Progenetix databases had used pubmed: for PubMed identifiers and ncit:
for NCI Metathesaurus (Neoplasm) ids.

Loss of heterozygosity (LOH) is a phenomenon frequently observed in cancer genomes where the selective pressure to keep only the susceptible gene product from one allele removes the other healthy allele from the pool; In this context, copy neutral - loss of heterozygosity (CN-LOH) is commonly observed in haematological malignancies (O’keefe et al., 2010 and Mulligan et al., 2007). To Progenetix oncogenomic resource, comprising of nearly 800 cancer types (by NCIt classification) as of 2021, we expanded the new feature of LOH in our data collection, in addition to the total copy number, to open the door for the analysis of frequency and impact of this phenomenon.
Update 2021-01-28:
LOH variants can now be queried through the Search and Beacon+ interfaces, either as specific variants or together with deletions.
Please be aware that in contrast to the “complete for chromosomes 1-22” DUP and DEL calls, LOH is only determined for a subset of samples and therefore will be underreported in the statistics section.

.pgxsegProgenetix uses a variation of a standard tab-separated columnar text file such as produced by array or sequencing CNV software, with an optional metadata header for e.g. plot or grouping instructions.
Wile the first edition only was geared towards sample-linked segment annotations, a variation is now being provided for CNV frequencies.

The standard format for (plot-)images generated on Progenetix is Scalable Vector Graphics (SVG). As the name implies, SVG is scalable, i.e. images can be scaled up without loosing quality or expanding in storage size. However, some of teh generated images use also embedded rastered components which will deteriorate during scaling - this is e.g. the case for array probe plots.
According to Wikipedia
All major modern web browsers—including Mozilla Firefox, Internet Explorer, Google Chrome, Opera, Safari, and Microsoft Edge—have SVG rendering support
On most pages where plots are being displayed there is a download option for the images - (please alert us where those are missing). Browsers also have the option to export SVGs themselves e.g. as PDF.
