Continue collaboration with Linked GTFS #2

Open pietercolpaert opened 2 years ago

pietercolpaert commented 2 years ago

In the past UPM and IDLab collaborated on the creation of Linked GTFS: https://github.com/OpenTransport/linked-gtfs

Does it make sense to link these ontologies together and maybe put the GTFS-RT terms in the namespace of Linked GTFS?

Sure, it may be nice to do. Currently a bit busy with some other additional activities (this work was done in the context of a project under INDRA's supervision), but happy to take on this once that there is a bit more free time to work on it. If you start proposing some changes and make pull requests, we can review them and start the process.

I wonder how to make these initiatives more sustainable beyond academic projects. Do you have any ideas on that? My approach so far has always been to try to get the Linked Data publishing as close as possible to the standardizing committee.

E.g., with DATEX2 this translated to CEN publishing some JSON-LD here: https://datex2.eu/vocab/3/Common/

However, this is also criticized within the RDF community. While it is quite sustainable, it is not a Linked Data-first spec, and therefore harder to apply within the RDF world: it doesn’t follow ontology design pattern we are used to in the RDF world.

That is a first step, sure, and a way to get the community to know the benefits of such an approach, but in the long-term it has also some difficulties in showing the advantages of data integration.

Ideally, sustainability should come from a more continued and dedicated funding for the effort required on these activities.
