Linked Connections

The vocabulary just added the term for an Unscheduled Connection. Useful to indicate a connection was once scheduled but not anymore now, and contrary to a Cancelled Connections should not be taken into account for route planning results semweb.mmlab.be/ns/linkedconne…

TIL 99% of my compatriots live at < 1km from a public transport stop. That's impressive, imo

We are featured with an end-user perceived performance study in the book “situating open data – global trends in local contexts”! @DanLammerhirt @julianr1987 @EvelineVlas Full text: africanminds.co.za/wp-content/upl…

Here's a brand new fast and lightweight streaming Microdata to RDF parser for JavaScript: github.com/rubensworks/mi… It's fully compliant to the latest Microdata to RDF editor's draft: w3c.github.io/microdata-rdf/ #RDF #Microdata #JavaScript \cc @danbri

Insights about how to fragment public transport networks in smaller fragments by @IDLabResearch. The paper won the best student paper award!

Happy I presented our work on efficient live public transit data sharing @ #ICWE2020 next to many great presentations! in short: -server pushing saves client bandwidth use but raises server cost -client side algorithm processing allows faster route updates julianrojas.org/papers/icwe202…

We are making baby steps progress on automated querying of #opentransport data. This example is a federated SPARQL query over @wikidata and @iRail to get all stations with an opening date after 2000 where trains are currently departing. #comunica #datasources=https%3A%2F%2Fgraph.irail.be%2Fsncb%2Fconnections;https%3A%2F%2Fquery.wikidata.org%2Fbigdata%2Fldf&query=SELECT%20%3FofficialOpening%20%3FdepartureStop%20%3Flabel%20%3FwikidataDepartureStop%20WHERE%20%7B%0A%20GRAPH%20%3Fg%20%7B%0A%20%20%20%09%3Fconnection%20%3Chttp%3A%2F%2Fsemweb.mmlab.be%2Fns%2Flinkedconnections%23departureStop%3E%20%3FdepartureStop%20.%0A%20%20%7D%0A%20%20%0A%20%20%3FwikidataDepartureStop%20%3Chttp%3A%2F%2Fwww.wikidata.org%2Fprop%2Fdirect%2FP2888%3E%20%3FdepartureStop%20%3B%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%0A%09%09%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23label%3E%20%3Flabel%3B%0A%20%20%20%20%20%20%20%3Chttp%3A%2F%2Fwww.wikidata.org%2Fprop%2Fdirect%2FP1619%3E%20%3FofficialOpening%20.%0A%20%20FILTER(YEAR(%3FofficialOpening)%20%3E%202000)%0A%7D" target="_blank" rel="nofollow noopener">query.linkeddatafragments.org/#datasources=h…

@dchavesf @oSocode_es @snapEUproject @rml_io Is there a link to a repository already? Would love to follow along!

@linkedcons @oSocode_es @snapEUproject Our application ONETT uses Semantic Web technologies (@rml_io and #yarrrml mappings) to transform from #GTFS to the #Transmodel Ontology. Great GIF by our talented students describing the project!

And that’s not all. Next to the Belgian edition, @dchavesf is also at the Spanish @oSocode_es coaching public transport projects as part of the @snapEUproject

We are at #oSoc19. Our main research team (@julianr1987, Harm Delva and @pietercolpaert) coaches 5 teams on creating individual route planning projects. We’ll tweet about the results next week, in the meantime find out more at summerofcode.be

We release version 1.0.0 of GTFS-RT to Linked Connections. @julianr1987 added support for GTFS-RT2.0 github.com/linkedconnecti…
