Produce flat version of DUO #14
Comments

It's possible that a JSON Schema from an ontology could be very useful more boradly, considering SchemaBlocks and Search. There's been some previous (but now abandoned) work on owl to JSON Schema, so it's possible. The Human Cell Atlas has already written a JSON Schema extension to support the use of ontologies, but I don't know how this works for them in practice. There are a few possibilities here, and one could be that having onotlogies in JSON Schema files isn't needed, if a formal vocabulary extension is written for JSON Schema, but then you have possible tooling issues. A simple JSON Schema which has an enum of all the terms, while large, may still be quite useful. Annotation fields could be used to include the descriptions and other meta information. Just some thoughts =] |

Hi @Relequestual - thanks for the thoughts! I think the discussion about a JSON schema is broader scope than this ticket, which is really only about producing a table/CSV file for the DUO terms (as per the output of the SPARQL query). But nonetheless a very interesting one, so I'll reply here and we can always move it if/as needed. I'll tag people I know are involved in those and related efforts to be sure we're covering a wide scope and others have a chance to be aware/pitch in. @cmungall was involved on the OWL-JSON front so may be able to comment on this (or a new ticket/email if better suited?) As far as I know the HCA ontology extension works well (pinging @lauraclarke) and is being used in production, and definitively something we may be interested in eg to constrain restrictions to specific subclasses of disease. When I looked into this @simonjupp said
@mbrush also had ideas how those restrictions/patterns could be better formalised in the OWL file and he offered to write proposals/tickets for those. Either way, we should be able if we know the top-level class to fetch all (in)direct subclasses (eg via OLS API) if it was a requirement from a driver project to have a list/enum of all possible values. |

We're producing json for a number of ontologies now. Robot and odk support
it. May be a good idea for duo to include this in its release pipeline

Here’s an example from the HCA of JSON schema for an disease term
https://github.com/HumanCellAtlas/metadata-schema/blob/master/json_schema/module/ontology/disease_ontology.json
We also have a python based validator
https://github.com/HumanCellAtlas/ingest-validator/tree/master/ontologyvalidator
USI have a node.js based validator that is better documented
https://github.com/EMBL-EBI-SUBS/json-schema-validator/blob/master/README.md
@mbrush <https://github.com/mbrush> also had ideas how those
restrictions/patterns could be better formalised in the OWL file and he

Either way, we should be able if we know the top-level class to fetch all

if it was a requirement from a driver project to have a list/enum of all
possible values.

The HCA validator is a different thing from building a JSON schema from an ontology but I'll add the links in here anyway for completeness. This validates terms against the OLS API using custom keyword extensions and the AJV validator. https://github.com/elixir-europe/json-schema-validator |

This has now been done and will propagate to the PURL system, OBOFoundry/purl.obolibrary.org#605 |
Our automated release pipeline could query the EBI RDF platform using the SPARQL query below.
We could then export the result as CSV, HTML or else - tbd with Adrian, Dylan and the group.
