-
Step 0: Materialize Nextflow and CWL workflows from WorkflowHub. Downloading an RO-Crate using the TRS API of WorkflowHub to materialize workflows.
-
Step 1: Materialize remote repositories that contains the materialized workflows.
-
Step 2: Materialize inputs to launch the workflows. Using a file that contains the ids or data references to the inputs, that we are going to use to instantiate the workflows. For example: (wetlab2variations_execution_cwl.yaml)
-
Step 3: Setup Nextflow and CWL engines.
-
Step 4: Validate workflows and materialize their containers.
-
Step 5: Launch the workflows in an execution environment.
-
Step 5.a: Launch workflows in a FUSE encrypted filesystem.
-
Step 5.b: Launch CWL workflows in an execution environment.
-
Step 5.c: Launch Nextflow workflows in an execution environment.
-
Step 5.d: Generalize the number of workflows which can share the same working directory, so outputs of one can feed inputs of others.
-
-
Step 6: Integrate or delegate the use of Crypt4GH into the process when requested, so outputs are encrypted for the researcher, allowing moving them with no data disclose.
-
Step 6.a: Use Crypt4GH to encrypt the passphrase of FUSE encrypted execution working directories.
-
Step 6.b: Create a micro CWL workflow which uses Crypt4GH to decrypt one or more files (depends on
5.d
). -
Step 6.c: Create a micro CWL workflow which uses Crypt4GH to encrypt one or more files (depends on
5.d
).
-
-
Step 7: Add upload capabilities of results, which generate permanent identifiers.
-
Step 7.a: Upload to cache system.
-
Step 7.b: Upload to WebDAV server.
-
Step 7.c: Upload to FTP server.
-
Step 7.d: Upload to SFTP server.
-
Step 7.e: Upload to Nextcloud and generate share link.
-
Step 7.f: Upload workflow to WorkflowHub.
-
Step 7.g: Upload to Zenodo.
-
Step 7.h: Upload to B2SHARE.
-
Step 7.i: Upload to osf.io .
-
Setp 7.j: Explore datacite doi service.
-
-
Step 8: (partially implemented) Create execution provenance, which includes uploading URLs of results and / or DOIs / URIs.
-
Step 9: Generate RO-Crate from execution provenance and exported results.
-
Step 9.a: Generated RO-Crate should be consumable by WorkflowHub.
-
Step 9.c: Generated RO-Crate should be consumable by WfExS-backend.
-
Step 9.d: Add full circle capabilities. Re-execute workflow with the very same parameters from previously generated RO-Crate.
-
-
Create a JSON Schema formally describing the different configuration files.
-
Supporting
file
protocol and lean and mean paths, so WfExS can be used with local routes and paths. The main drawback is that RO-Crate provenance can suffer in these scenarios, as it is not provided a public URL/URI. -
Support conda-based workflows.
-
Support Snakemake workflows.
-
Support pre and post processing steps through the usage of side workflow executions.
-
Generate an abstract CWL description of a workflow execution. In the case of CWL will be a no-op, in the case of Nextflow it will use execution provenance.
-
Integrate GA4GH API providers which do not support returning an RO-Crate dockstore.org.
