+As part of the COVID-19 Biohackathon 2020 we formed a working group
+to create a COVID-19 Public Sequence Resource (COVID-19 PubSeq) for
+Corona virus sequences. The general idea is to create a repository
+that has a low barrier to entry for uploading sequence data using best
+practices. I.e., data published with a creative commons 4.0 (CC-4.0)
+license with metadata using state-of-the art standards and, perhaps
+most importantly, providing standardised workflows that get triggered
+on upload, so that results are immediately available in standardised
+data formats.

+This means that when someone uploads a SARS-CoV-2 sequence using one

+this metadata gets transformed into an RDF database which means
+information can easily be fetched related to uploaded sequences.
+We'll show an example below where we query a live database.
+</p>
+
+<p>
+There is more: when a new sequence gets uploaded COVID-19 PubSeq kicks
+in with a number of workflows running in the cloud. These workflows
+generate a fresh variation graph (GFA) containing all sequences, an
+RDF file containing metadata, and an RDF file containing the variation
+graph in triples. Soon we will at multi sequence alignments (MSA) and
+more. Anyone can contribute data, tools and workflows to this
+initiative!

+The latest run of the pipeline can be viewed <a href="https://workbench.lugli.arvadosapi.com/collections/lugli-4zz18-z513nlpqm03hpca">here</a>. Each of these

+</p>
+
+<p>
+If you download the GFA or FASTA sequences you'll find sequences are
+named something like
+<b>keep:e17abc8a0269875ed4cfbff5d9897c6c+123/sequence.fasta</b> which
+refers to an internal Arvados Keep representation of the FASTA
+sequence. Keep is content-addressable which means that the value
+e17abc8a0269875ed4cfbff5d9897c6c uniquely identifies the file by its
+contents. If the contents change, the identifier changes! We use
+these identifiers throughout.
